The first audio format in computer games

Audio Format

The first mention of computer sound came from the creation of primitive games at the time, in which sound was played through the system’s speaker. But no matter how hard the developers of such software (software) have been, the required quality, compatible with tape or reel recordings or recorders, could not be achieved.

High definition digital music has been around for a long time. Why does it seem that it is now catching on? In addition to traction, they can have devices like one, the answer on the market. The author of this disappearance does not have to look very far. Except in special cases, most of the users are more than enough for their smartphone to listen to music. Even players that have settled down, you see, they reduce the ground they hit year after year.

That is why many manufacturers are looking for a solution on how to change the audio format so that the sound is natural. Frankly, this has led to more competition than we have now. This applies not only to the material being played, but also to studio sound, live performances, quality or basic parameter settings in terms of knowledge of physics, acoustics, etc.

We come to the millionth question. This requires a sensitive ear and some education. If you’re a high-profile foodie, you’ll probably know the difference first, but for ordinary mortals who only listen to music with a background meter, it’s probably too hard to pay the difference just to have that kind of quality.

It is not just a music player. Those that combine with this equipment are not cheap. To top it all, there is music that is sold in high definition formats, which is also a bit more expensive. Finally, this is the technical section. There is not even consensus among audio professionals themselves on whether these devices make such an important distinction. At least on paper, it seems that HD music sounds better, but there is a strong marketing component behind it. Are we willing to pay to see the audience as music lovers?

The appearance of the WAV format
It is believed that the first full quality of audio formats was associated with the appearance of the standard and the .wav file extension (this abbreviation was formed from the English word “wave” or wave). Anyway, he became the first-born that could be processed into computer programs on a professional level.

As is usual in most multimedia files with which we work almost daily, we link to video with photos or audio files, depending on the type of use that we are going to make of them, we must use them in a specific format, so It is also important to know the main differences between them.

But this is what we are going to talk about, these are some alternatives that we are going to present to you and that will be very helpful when it comes to testing and converting the different types of audio files that we usually find. If you want to know the main differences between the two, we recommend that you take a look at this post that we offer you.

DTS audio formats

DTS – Digital Theater System, in fact, is Dolby Digital, or rather its competitor. DTS uses a lower compression rate than Dolby, so it actually sounds better, as evidenced by DVDs that have DTS or DD tracks. DTS in home theater systems uses a maximum bit rate of 1536 kbps (full bit rate), this sound is better than Dolby Digital’s AC-3 format. DTS – Uses 6 free audio tracks and supports 7.1 sound distribution system, with this DTS 4.0 bit rate – it will sound as immersive as Dolby 5.1.

AIFF VS FLAC

FLAC

FLAC – (Free Lossless Audio Codec). Unlike lossy codecs (MP3, Ogg, and AAC), it does not remove any information from the audio stream and is designed for listening to music on high-quality Hi-Fi and Hi-End equipment and for archiving a professional audio collection. Currently, the FLAC format is supported by many audio players and music applications. The basic decoder uses ID3v1 and ID3v2 tags to store basic types of metadata, so they can be freely added and edited.

MIDI

MIDI: (Musical Instrument Digital Interface), unlike other formats, MIDI does not store digital sound, but sets of commands: notes played, links to instruments, sound parameters. The convenience of the MIDI format is to use a device that is arranged according to the indicated chords. Midi files are typically several orders of magnitude smaller than digitized audio of the same quality. The MIDI format is versatile and designed so that any sequencer can read and write data without loss. At the same time, MIDI information that is incomprehensible to other software applications does not lead to misunderstandings, but is simply ignored. The mid-year backing track format allows you to save information about the instrument used, the tempo, the size designation, the information about the musical keys, the name of the track and the patterns and their number.

MP3

MP3: (MPEG Layer version 3) At the moment, MP3 is the most popular digital music encoding format. MP3 is a lossy compression format, that is, part of the audio information, according to the psychoacoustic model, the human ear can barely perceive is removed from the original file, irrevocably. The debate on MP3 quality still continues … First, the quality of the resulting MP3 depends not only on the bit rate of the compressed file, but also on the version of the encoding program used: the codec. Many music gourmets prefer to compress music with “maximum quality” – 320 kbps, or switch to other formats, for example FLAC, where the average bit rate is ~ 1000 kbps. At the moment, MP3 is the leader in universal recognition, but at the same time it is not a professional format in terms of technique. Professional musicians and DJs no longer use tracks with a bit rate lower than 320 kbps.

MODIFICATION

MOD is a format designed for the Amiga platform. Each MOD file contains digitized recordings of actual instrument sounds, called samples, somewhat similar to the structure of MIDI. Cj or a composer who writes in the MOD format uses a program called a tracker, in which he specifies what instrument, at what time, what note and octave should sound; This sequence of notes is written in a list; one track and several tracks. sounding in parallel forms a block called a pattern. The pattern collection forms a module: a file in MOD format, with the extension .mod. A track bar corresponds to an actual channel in which cj can play or edit numbered notes. Notes can be assigned various “patterns”, for example: tremolo, glissando, and so on.

OGG

OGG – Vorbis was developed in 2002 by the Xiphophorus team as an alternative to all paid licensed audio formats. Ogg Vorbis is compatible with all popular platforms. The format does not restrict the user to just two channels of audio (left and right), it supports up to 255 separate channels at a sample rate of up to 192 kHz and up to 32 bits, making Vorbis ideal for encoding DVD-Audio of 6 channels. home theater audio.

Various physical methods have been developed to store audio data for these purposes, such as vinyl records, magnetic tape, CD, DAT, MD (minidisc), DVD, or converting music scores to music (MIDI), in the same way.

Audio File Formats

Many different computing methods have emerged. Audio data storage – digital: OGG, Mp3, Flac, Wav formats.
It is impossible to consider and discuss all audio formats, codecs, their advantages and disadvantages, so in our article we will try to talk about the most popular audio file extensions that you may have to work with.
Why can’t we use any universal audio file encoding format?

Because for the implementation of various functions, a different format is required. For example: to play CDs in a CD-ROM drive, to record music or sound effects in video games, to record a movie track or video clip, to play on mobile phones or transfer files over the Internet, in addition, there are a number of of operating systems that are the most used in the world. These include: Amiga, Macintosh, NEXT, and Windows personal computers. Also, the job of a dj, sound engineer, cj, video engineer, or a simple music lover is quite different in nature. This may require that your audio data be saved in your own way. For example, the audio on a CD must be saved using 16 bits and a sampling frequency of 44.1 kHz. However, to download sound over the Internet, it is better to use a different bit depth and sample rate, as each minute of 16-bit, 44-kilohertz audio takes about 10MB. those. an average 5 minute track will be 50 “meters” – this is too much information for the average user. This article presents brief information on the most popular music formats.

AA (audible audiobook file)

AA (Audible Audio Book File) is a proprietary format developed by Audible. It is used to record audiobooks that are sold through the Audible and iTunes services. It is possible to reduce or accelerate the speed of listening to files: digital tone, the ability to leave bookmarks when listening to audiobooks, file protection, when delivering sound recordings over the Internet.

AAC (advanced audio coding)

AAC (Advanced Audio Coding) is an audio file format with less loss of quality when encoding than MP3 in the same sizes. Lossless music encoding of original quality using the ALAC profile. AAC is a family of MPEG4 audio coding algorithms. Unlike the hybrid mp3 filter bank, AAC uses MDST (Modified Cosine Transform) technology, which means that the listener gets better sound quality than MP3 encoding with the same or lower bit rate. Possible AAC file extensions: .m4a. m4b .m4p.

AIFF

AIFF – This is the audio data format for the Apple Macintosh platform. The .aiff format supports 8- and 16-bit mono and stereo. If files in this format contain a Mac-Binary header (text, photos, copyright holder information, a single number, etc.), then the file will have the extension .snd. You can listen to an audio file with the extension .nd using Sound Forge. Forge will, of course, open such a file, but it will recognize it as a Macintosh resource format and it will not affect sound quality.

APE (mono audio)

APE – (Monkey’s Audio), developed by Matthew T. Ashland is a lossless digital audio format. Monkey’s audio codec is released for Microsoft Windows platform only, although there are several unofficial codecs for MacOS, Linux, BeOS Monkey’s audio files use the following extensions: .ape to store audio and .apl to store metadata This format is not free as its license severely restricts the distribution of .ape files.

Surely, many users prefer to use their home computer not only as a workhorse, but also as a multimedia center where they can watch movies or family photos, as well as listen to their favorite music. Although compact digital players or mobile phones are certainly more suitable for listening to musical compositions, but unlike them, a computer can not only play music.

No matter how big the built-in memory of your music player is, it will most likely be difficult to store your entire music library on it. Plus, you can create, edit, organize, and search for music with your PC. Also, don’t forget that there are around three dozen common digital audio formats today, and most players are far from omnivorous and can only play a few of them.

So why do you need to create so many music formats to store one type of content? The fact is that, in the vast majority of cases, the sound is stored in “compressed” form, since one minute of uncompressed composition occupies about 10 MB on the hard disk. On the one hand, this seems not to be much, but on the other, if you are a music lover and your collection consists of several hundred or even thousands of songs, then it is clear that the sound must be compressed to reduce the space it occupies in electronic media.

Various special algorithms are used to compress music files, which subsequently determine the structure and presentation of the audio data, or so-called digital audio file formats. All audio formats can be divided into three groups: uncompressed audio formats, lossless compression, and lossy compression.

No compression
One of the most widespread formats related to this type is the well-known WAV. The sound of files with this extension is stored without compression or changes. It is true that much more space is required to store uncompressed files and therefore WAV is more widely used only in professional audio and video applications, where the sound should not have a loss of quality before processing. Keeping ordinary musical compositions in this form is unwarranted waste.

To play WAV files, you do not need any special software, as all media players understand this format, including the standard Windows Media audio player built into the Windows system.

Another format used to store uncompressed audio that is worth mentioning is Apple’s development called AIFF (Audio Interchange File Format). As you may have guessed, it is most commonly used on Macintosh computers running Mac OS X.

Lossless compression (lossless)
Lossless compression algorithms for audio files work on the principle of conventional file cabinets. They do not provide the highest level of compression (40 to 60%), while they have virtually no effect on sound quality. It is also worth noting that in this case, the encrypted data can be fully restored to its original form. Therefore, the use of lossless compression is most often used in cases where it is important to preserve the identity of the compressed data with respect to the original.

The most popular audio formats in this group are FLAC (Free Lossless Audio Codec), APE (Monkey’s Audio), WMA (Windows Media Lossless), and ALAC (Apple Lossless Audio Codec). Each has its own pros and cons. For example, the APE codec offers slightly better compression gains, while FLAC is more common. In general, all true music lovers store their music collections in lossless formats, since they do not remove any data from the audio stream and files created with these codecs can be listened to even on high-quality stereos.

Frequently asked questions about audio formats

Frequently asked questions about audio formats

The rapid development of computer technology and the Internet has led to the need to create digital formats that could be stored and reproduced on computers without the use of any physical medium. As a result, various types of digital audio formats have been developed.

Types of digital audio formats
All digital audio formats can be divided into 3 groups according to the principle (codec) used to compress audio data, namely:

Lossy formats
These are audio formats that use a lossy compression method for audio data. That is, when encoding a digital audio recording with any of the lossy codecs, certain changes are made to the audio data. This can significantly reduce the size of the resulting file, but at the same time leads to a deterioration in sound quality. The most popular lossy formats include MP3, WMA, Ogg Vorbis, AAC, and others.

Advantages and disadvantages of lossy audio formats
The main advantage of lossy formats is the small file size, while maintaining acceptable quality for listening. Furthermore, these audio formats are compatible with the vast majority of electronic devices and music players, including home audio systems, radio recorders, and MP3 players.

The main drawback is the loss of sound quality compared to the original. If you convert an audio recording from an original licensed audio CD to a lossy format, when you play the resulting file, the sound will be worse than that of the source.

Lossy formats sound bad?
No way. First, when lossy encoding, there is a choice of compression ratio and sound quality. For example, if we are talking about the MP3 format, then to record a voice (audiobooks, audio tracks for a textbook in a foreign language), the CBR 128 kbps quality will be enough, but for music, the ideal option is CBR 320 kbps. It is worth noting that CBR is short for ConstantBit Rate, which stands for Constant Bitrate.

Second, the compression process uses the principle of removing from the recording those frequencies and sounds that a person cannot hear by nature. There is an opinion, confirmed by many experiments, that music compositions in high quality MP3 format (CBR 320 kbps) cannot be distinguished by ear from the original recording or from a licensed audio CD purchased from a store.

Lossless audio format
This is a type of digital audio format in which the audio data is encoded without loss of quality. The sound will not differ from the source in any way, be it a licensed music CD (CDA format) or a digitized vinyl head, saved in uncompressed WAV format (for Windows) or its analog AIFF (for iOS). The most popular lossless formats are FLAC, Monkey’s Audio, ALAC, WavPack, MWA Lossless.

This makes lossless audio formats ideal for listening to music on good audio equipment. For example, in high-end home speakers or Hi-Fi systems and high-end headphones.

Advantages and disadvantages of lossless formats
The main advantage of lossless audio formats is that during encoding and decoding, the program does not remove any data from the audio stream. Because of this, when playing such files, the listener receives the original sound without disturbance.
But lossless audio formats also have a major drawback. The fact is that many devices for playing sound files do not yet support these formats. You can solve the problem by purchasing the right type of equipment, for example a portable Hi-Fi player or a media player, as well as a home audio system that supports lossless audio formats.

Main digital audio formats

Main digital audio formats

–MP3: was created by Moving Pictures Experts Group (MPEG), which created and continues to create standards for storing and transmitting audio and video in digital format. In its entirety, the format is called: MPEG-1 / MPEG-2 Layer 3 (MP3). It is the most popular music storage format in the world today.

MP3 simultaneously compresses data and processes audio to obtain the smallest possible file size. The bit rate can vary from 8 Kb / s to 320 Kb / s, the sampling rate from 16 kHz to 48 kHz. The goal of processing the original recording with the MP3 compression algorithm is to compress the information as little as possible. So if in its original form a song occupies around 70 MB of memory, then in MP3 format with acceptable quality it will only take around 7-8 MB, as you can see, the gain is significant, although it is achieved by degrading the sound quality .

–AAC: The format has become popular because Apple has adopted it as a standard for storing, selling and distributing music in its ecosystem and iTunes. AAC is very similar to MP3 in terms of audio processing during encoding, although it gives a slightly better result.
Furthermore, AAC not only compresses the data, but also performs sound processing, removing a certain type of data, thus achieving significant savings in memory for storing music. The bit rate can range from 8 kbps to 320 kbps, the sample rate ranges from 8 kHz to 96 kHz. With more sophisticated and sophisticated encoding and compression algorithms, AAC music can sound better than MP3 and take up less memory. Another advantage of the AAC format is that it supports up to 48 channels, while MP3 only supports 2.

–WMA: format developed by Microsoft to compete with MP3. During encoding, data is compressed, music is processed, and parts of it are removed, saving memory. However, there is a variation of the format called WMA Lossless that preserves the quality of the original sound. The vast majority of modern phones, players and computers support this format and there should be no problems with its playback. However, some computers may have a hard time playing them, so if you want maximum compatibility, MP3 may be worth choosing.

–FLAC: Developed by the Xiph.Org organization, this format is free for any type of use, so it is quite widespread these days.
FLAC uses data compression, however it preserves the original sound quality of the recording. music is not processed. The recording quality can be 32-bit / 96 kHz (this is significantly higher than the recording quality of CDs, which is 16-bit / 44.1 kHz). The data compression algorithm can save up to 30% memory compared to the original recording, while maintaining perfect sound quality. It is for this reason that the FLAC format has become very common.

–ALAC: this format is analogous to FLAC, but made by Apple, whose full name is Apple Lossless Audio Codec. Its properties are the same as those of FLAC, but its advantage was that all Apple devices could work with it without the need to install third-party applications. Since iOS 11, the FLAC format has also become fully compatible with Apple devices, so the urgent need for ALAC has decreased significantly for the sake of freedom and the greater compatibility with other devices that FLAC offers.

–WAV: A format developed by Microsoft, this format stores the sound in its original form, so the files take up a lot of memory, although they preserve the perfect quality of the music.
WAV does not compress or process sound, we can say that it is an ideal format for storing master copies and for subsequent sound processing. Although there are certain encoding settings that allow you to compress data, they are generally not used. WAV files are similar in storage method to PCM and AIFF formats.

–AIFF: a format also developed by Apple, the full name is Audio Interchange File Format. The main goal is to store music on Apple computers in its original form.
AIFF doesn’t compress data or perform any sound processing, so like WAV it takes up a lot of memory. The best sound storage format if you want to keep processing it in an editor or convert it to other formats on Mac computers.

–PCM: This format is used for digital recording of analog signals, which is sound. It is a standard for recording audio to CDs, but can also be used to store music digitally in computer memory. PCM does not compress audio, ideal for storing master copies of music or for professional audio work.

Installations
Installation first. There is no perfect format. Different types of audio require different approaches.

Audio Formats

Second installation. It is impossible to do something good with poor quality.

Third installation. There are three approaches to comparing quality: the discriminating edge (heavyweights), the comforting edge (consumer audio), and the intelligibility edge.

Fourth installation. Disputes in a weight category are useless and are called “holivars”. The arguments in different weight classes are meaningless: “heavy is heavier than light” and “light is lighter than heavy.” Disputes (especially between heavyweights) can only take place with the support of the “blind method”.

A brief introduction
Bit rate is one of the most important metrics for measuring digital audio recordings. It is measured in kilobits per second (for short: kbps, just kilobits, kbps, kbps, kbps, etc.).

On the fingers: answer the question “how much memory occupies a second of audio”.

All kinds of transformations are already underway: there are eight bits in a byte, 1024 bits in a kilobit, 60 seconds in a minute, 60 minutes in an hour, and we arrive at the following empirical data:

bit rate 1400 = 1 hour takes 615 megabytes on disk
320 bitrate = 1 hour takes 141 megabytes on disk
bit rate 192 = 1 hour takes 84 megabytes on disk
bit rate 24 = 1 hour takes 11 megabytes on disk
Naturally, we all want to use disk space sparingly. This is where the format war begins. 11 MB is sixty times cheaper than 615 MB. Megabytes is the cost of storing audio recordings.

The price of storage can also be expressed in bills, dividing the cost of the disk by its capacity. For an archive of audio recordings, the storage price is far from being as critical as for an archive of video recordings.

Furthermore, the storage price can be conditionally expressed in man-hours, if the playback device has a much smaller capacity than your general archive of audio recordings. It takes time to regularly download new tracks to the device.

The storage price can also be expressed in square meters of work area. 500 audio CDs will take up a lot of space and require furniture solutions, but a small external hard drive fits in your pocket.

If there is a different price, then the question of quality arises: then we assume that the lowest bitrate has the lowest quality. So we come to the main question: where is the limit of reason, where is the ideal “price / quality” ratio.

The most approximate division of audio formats in descending order of average bitrate:

uncompressed audio
lossless compression
lossy compression

Uncompressed audio is the pure signal without conversion, “as is”, the equivalent of WAV or audio CD. Classic parameters: 1411 kbps, 44100 kHz sample rate, 16-bit audio.

Codec is an abbreviation of the words (KO der and DEC oder). An encoder is a program that packages a pure audio signal in the desired special format. A decoder is a program that converts a special format into a pure audio signal. In modern English, the two terms were transformed a bit: below code and below code, which corresponds to the direct Russian counterparts for coding and racing coding. And do not confuse encryption and encryption: these are two very different processes, although externally there is a lot of similarity.

For an ordinary person, only a player that can work with this format is required (that is, it has a decoder). The “encoder” itself is only required to “create” such files.

Lossless compression – Typically used for collectible audio material. It is generally believed that this format can be converted exactly to Audio CD.

Better is this compression:

Save disk space by about half
The file format assumes the storage of additional information (artist, album, track number, track name, etc.)
The compression formats themselves differ:

format openness and compression algorithms
player support
overhead encoding, decoding costs
compression ratio
The overhead costs are negligible for the average person and the compression ratio of the codecs differs slightly. Main actors: FLAC, APE, WAVPACK, ALAC.

Lossy Compression – Provides a much higher compression ratio by discarding unimportant audio details. The smaller the size of the file we are trying to compress, the more details we will need to discard. In addition to the disappearing details, technical artifacts also appear.

Audio formats

Audio formats

The audio format is a type of computer file that contains music. There are lossless uncompressed, lossless compressed and lossy music audio formats.

Bit rates
Bit rate is a unit of measurement for data that indicates the number of bits transmitted in a given time. When it comes to music formats, the bit rate is expressed in kilobits per second (kbps) transmitted. If you compare the same song encoded at different bit rates, the file with the highest bit rate will be of higher quality. For example, a 320 kbps (CBR) MP3 file transmits 320 kilobits for every second of the audio stream.

Audio formats containing uncompressed lossless data (Uncompressed Lossless)
Lossless uncompressed data formats retain all original recorded information. Since silence is encoded at the same number of bits per second as sound, files containing uncompressed lossless data are often large. Formats containing lossless and uncompressed data are encoded using pulse code modulation (PCM). Examples:

WAV (PCM) (used in Windows)
AIFF (PCM) (used in Mac OS).
Audio formats containing lossless compressed data (Compressed Lossless)
Lossless compressed formats store all original recorded information in a smaller volume than uncompressed lossless data when compressing data. Silence is encoded at the lowest bit rate and audio is compressed, so files that contain lossless compressed data are usually half the size (file size) of the same song in a format that contains non-data. uncompressed loss.

Since formats that contain compressed data without loss of quality and formats that contain uncompressed data without loss of quality both retain all the information from the original recording, they can be transcoded to each other without loss of quality. Examples:

Free Lossless Audio Codec (FLAC)
Apple Lossless Audio Codec (ALAC)
Mono Audio (APE).
Lossy audio formats
Lossy formats always compress data. Lossy audio formats are smaller than those that contain lossless compressed data and formats that contain uncompressed lossless data by removing some of the original information. These are usually high frequencies that most people cannot hear, however in some cases the difference in lossy and lossless audio formats can be very large.

Since lossy formats lose data during compression (and therefore sound quality), they CANNOT be transcoded to lossless or other lossy audio formats without further loss of sound quality. Examples:

MPEG Layer 3 Audio (MP3)
Advanced Audio Coding (AAC)
Windows Media Audio (WMA)
Dolby Digital 3 (AC3) audio codec
DTS Coherent Acoustics Codec (DTS).
File sizes
Here we can see how the file size of the same song depends on the format in which it is presented: uncompressed data without loss of quality, compressed data without loss of quality or loss of quality. Take Avril Lavigne’s classic pop song Sk8er Boi for example. The song is 3 minutes and 24 seconds long.

Lossless uncompressed format – WAV (PCM): 34.3 MB
Lossless compressed format – FLAC: 25.75 MB (25% compression)
Lossy format – MP3 320 (CBR): 7.78 MB (78% compression)
Sound transparency
Sound transparency is a term used to describe the sound characteristic of a lossy file. The sound of a lossy file is considered transparent if the average person cannot hear the difference between it and a lossless file with the same song, having listened to both files and not knowing in what sequence they were heard. For most people, MP3 192kbps (CBR) is considered transparent.

Allowed audio formats
While there are many types of lossy and lossless audio formats, only a few are allowed on RED.

Since some lossless audio formats can be transcoded to other lossless audio formats without loss of audio quality, the only lossless audio format allowed on RED is FLAC. You can always download FLAC and transcode it to ALAC (for iTunes) or any other lossless or lossy audio format you want.

Allowed lossy audio formats:

MP3 (the minimum bit rate for MP3 is 192 kbps (CBR))
AAC (can be replaced by any MP3 torrent except downloads purchased from the iTunes store and containing exclusive tracks from iTunes)
AC3 (usually found on DVD)
DTS (usually found on DVD)
MP3 is the most popular audio format on RED. We allow you to upload albums to AAC purchased from iTunes because they often contain bonus tracks from iTunes, and since AAC is a lossy format, it cannot be transcoded to other audio formats without losing sound quality. Also, AC3 and DTS are often found on DVD and are lossy audio formats, so they cannot be transcoded to other audio formats without losing sound quality.

What audio formats are there and how are they different?

What audio formats are there and how are they different?

Audio formats

When recording sound, the question arises which audio format to choose for disk storage. Almost all of today’s recording programs offer a multitude of options here, from highly compressed MP3 to uncompressed WAV files.

However, it’s easy to lose track in the jungle of different formats. We clarify what audio formats are available and what are the differences between the formats. FROM MP3 TO WAV, EVERYTHING YOU NEED TO KNOW ABOUT AUDIO FORMATS When you save your audio recordings digitally, they are in a specific format.

Audio Formats

Describes the structure of the file and contains all the audio signals. A distinction is generally made between two variants: uncompressed audio formats, which contain all the data, and compressed. With these, certain information is cut from the file. Compressed music formats can also be divided into lossless and lossy.

Uncompressed formats include the following: PCM (Raw Data) AIFF (Audio Interchange File Format) WAV CDDA (Compact Disc Digital Audio) The main compressed formats are: MP3 WMA (Windows Media Audio) / Lossless WMA AAC (Advanced Audio Coding) FLAC (Free Lossless Audio Codec)

This is what defines lossless formats. Uncompressed audio formats store all data in an audio file, including what the human ear cannot or can barely hear. This takes up a lot of storage space on the data carrier, but the sound quality is excellent. Lossless files are compressed to a certain extent to reduce file size.

However, this is done in such a way that no noticeable loss of quality can be detected. All original data is preserved, only the layout of the data is changed. These are lossy formats. One of the most popular lossy formats is the MP3 music format. Parts of the original file are removed to reduce storage space. Ideally, only information from the file that is not perceptible to humans is removed.

The higher the compression level, the smaller the file, but the quality also suffers with each further reduction. PROCESS YOUR AUDIO FILES EVEN MORE – SAVE STORAGE SPACE AND COMPRESS The most common uncompressed music formats are WAV and AIFF. If you record audio files on a digital audio workstation, you typically export them in one of these two formats and then process them.

If you want to save the data without any loss, but the original data must be preserved, first compress the files with an appropriate audio program in a lossless format, for example as a FLAC file. This takes up less space on the data carrier, so you can save a lot on external media and transmit the data.

Since all the information is still contained in the file and is simply unzipped when you open it, you can process these music files optimally: cutting, adding additional effects or soundtracks, or splitting the file, and all without the quality of the sound is affected. If you want to share your music and audio files, upload them to the network, send them by e-mail or if you want to save many files on a data medium, compression is essential.

You can also do this by using a corresponding audio program, some of which you can download for free from the Internet. Compression reduces the file size to a greater or lesser extent depending on the degree. At the same time, the audio file information that cannot be restored is lost. Be careful when compressing. Bit rates – this is what determines the quality of an audio file

Bit rate describes the amount of data that is processed in the music file per second. The higher the value, the higher the quality of the file. Uncompressed files typically have a bit rate of 1411 kilobytes. For example, if you convert a WAV file to MP3 format, you can set the bit rate, for example, to 192 or 320 Kb per second. THE DIFFERENT AUDIO FORMATS AT A GLANCE

What music format is suitable for what purpose and what are the sound differences?

Here you can find out when you should ideally use which format. Uncompressed formats: PCM, WAV PCM describes the raw data of an audio file. The format allows very high bit rates and therefore very high quality. The data is in the original and the sound corresponds to that of an audio CD. However, the PCM format consumes a lot of memory and cannot be played with all common audio programs that are designed for the MP3 format, for example. Therefore, you need a special program to process the flat file.

MP3? No thanks! Everything you need to know about audio files

WAV Format

In order to get your music with recordJet to all major stores, your audio files must meet some general requirements to be accepted by stores. Here we explain everything about MP3 and other file formats, as well as the requirements that stores have on audio files.

You have probably already noticed that you cannot load tracks as MP3 files into recordJet, but only in a certain WAV format. What seems annoying to some at first, however, has two important reasons: the sound quality and the avoidance of problems.

Audio Formats

WAV is actually just a container format in which audio data can be stored. The most popular are uncompressed WAV (E) files, which contain so-called PCM raw data and were created with a 16-bit sample size and a 44.1 kHz sample rate. When talking about WAV files (as is also here in this article), we usually mean exactly this variant, the so-called CD quality.

Uncompressed music files have the advantage that all the information in digital files is still available. This means that the music will sound almost as good when played back as the original recording. But at least as good as on a CD.

With a codec like FLAC (Free Lossless Audio Codec), audio files can be losslessly compressed and reduced to about half their original file size without loss of quality. This works in a similar way to packing files in zip format, only the process is specially designed for music.

MP3 (actually MPEG-1 Audio Layer III), on the other hand, is a method for lossy compression of music files. You don’t need to be a professional to hear the quality differences between WAV and highly compressed MP3 without problems. In the case of lossy compression, the file information that is as “insignificant” as possible is removed, so the file size is naturally reduced as well. For example, an audio file can be reduced from 35-60 MB to 3-8 MB by such compression.

Unfortunately, the more a sound file is compressed, the worse the sound quality, as more information is removed from the file. The amount of information from the original file that is still available can normally be read at the so-called bit rate: a song with 320 kbit / s (= kilobits per second) is less compressed and has better sound quality than a song with 192 kbit / s. With MP3 with 320 kbit / s bit rate, even a professional can hardly hear any difference in CD quality.

So why doesn’t recordJet accept MP3 files at high bit rate?
It’s simple: all stores want to receive music in a different file format. The most widespread are the WAV or FLAC formats. But MP3 at various levels of compression are also required. One of the reasons for our decision to trust WAV is that we always want to offer the highest quality possible. If we were to convert your MP3s again, more information from the file would be lost. Even if you hardly hear a difference in quality in the original MP3 compared to the uncompressed version, this may become audible after a new conversion. Also, there is not just one MP3 codec with one parameter. Different codecs produce different results. Therefore, the sound quality may vary despite the same bit rate.

And why then exactly PCM with a bit rate of 1411 kbit / s, a sample size of 16 bits and a sample rate of 44100 Hz?
As already mentioned, this specification is the standard for CD quality. No store has yet demanded higher quality levels, which are entirely possible. In addition, everyone who participates in music production knows this format. For these reasons, and to avoid misunderstandings and problems, we have defined this format as our standard. Also, due to good internet connections, files of this size are rarely a problem for uploading these days. This can certainly take a bit longer, but it should still be within an acceptable range.

Why is it not necessary, or worse yet, to add metadata or tags to the uploaded files?
Unfortunately, the metadata and tags are not 100% clearly defined in WAV files or are used differently by different audio programs. We always provide stores with high quality metadata and possibly tag the audio files, according to their standards.
