What is the highest quality music format right now?

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.

MAIN AUDIO FORMATS

Even the audio formats differ in their versatility and level of compression, and even if they are not as numerous as the video formats, it is better to look at the properties to get satisfactory results according to the requirements of our work.

Microsoft Wave [Extension: WAV] It is Microsoft’s proprietary format and is certainly the most widely used. This diffusion depends on commercial aspects and the fact that it is the most supported among the competitors. It has various compressions and is a versatile and highly editable format. For this reason, it is suitable for general digital audio, both for multimedia publications (although there are certainly better formats) and for desktop video (real standard). An excellent program for processing wave files (but also other formats) is CoolEdit.

MPEG Audio (extension: MPG / MP3) MP3 stands for MPEG1 Layer3. The MPEG algorithm, the basis of MP3, emerged from the need to develop a world standard for the representation of moving images and audio. This standard was developed in 1988 for the treatment of audio and video signals and has the special feature of compressing files and reducing them by 12 times compared to their natural size.

This high-compression format is based in particular on theories of psychoacoustics: each individual has a hearing that is sensitive to frequencies from 20 Hz to 20 kHz, and in particular the man perceives sounds between 2 and 4 kHz better. In addition, some sounds mask nearby frequencies so that you cannot hear all of the sounds.

These considerations have led to the development of an algorithm that eliminates all “redundant” noise for the human ear and achieves a high level of file compression and sound quality that is comparable to the digital and can be downloaded directly to your PC.

MP3 enables good results, making small and high quality playback compatible. An established audio standard is the MPEG Layer3 version, which produces very small files of excellent quality, an excellent compromise when duplicating and creating audio files on CD. The XingMPEG encoder is an excellent software for creating MP3s.

Given the prevalence and importance of the topic on a legal level, let’s find out what it is and what benefits we can achieve by using this MPEG format.

An audio CD generally contains 60 to 78 minutes and is characterized by a quantization level of 16 bits and a sampling rate of 44.1 kHz, ie 44,100 samples per second. The quantization level describes the maximum number of intensity levels that a single sample can hold: for example 8 bits = 256 levels (28), 16 bits = 65,356 levels (216). The higher the number of levels that the signal can assume, the more precise the signal reproduction.

There is approximately 650 MB of data on a normal audio CD.

Conventionally, to reduce the size, we can work in two ways: 1) Reduce the quantization: that is, convert the samples from 16 bits to 8 bits, but lose the dynamics, quality and get a lot of noise; 2) Reduce the sampling frequency. As a result, the frequency range would decrease in the event of a loss of resolution.

The MPEG format, on the other hand, reduces the amount of information stored and therefore significantly reduces the size of the files by filtering out unimportant audio information according to the models developed on this basis. From research on the perception of the human ear, you decide which information is important and which is not . These studies have enabled us to know how our brain analyzes sounds, except irrelevant ones that are imperceptible (e.g. ultrasound).

The MPEG audio format also performs this process of removing intelligent weak signals. So if there is a strong signal, the weakest signal is not perceived.

When using a high compression rate, the MPEG encoder eliminates parts of audible information that are still of minor importance. With a slight compression rate, the difference to the uncompressed original is minimal.

Layers I, II, III can be viewed as the layers through which the MPEG format has evolved. All layers are based on the same perceptual coding scheme, the complexity of which increases for each of them. Layer II has superior quality at lower bit rates than Layer I; However, the most complex coding system currently available is Layer III,

MP4 (Extension: MP4) is an audio compression technology recently launched by Global Music Outlet (GMO) under license from AT&T Labs (January 99). As you understand, it is a further development of the MP3 format and seems to offer the ability to offer it a higher compression factor, which should even reach a factor of 16. Although the name is very similar, conceptually it has nothing to do with layer 3 and is actually in direct competition with it. Compressed MP4 files are presented as executable Win9x or WinNT files and offer the relatively encapsulated player.

Audio exchange (extension: AIF / AIFF) Format created to standardize the various audio standards between PC and Machintosh.

Microsoft NetShow (Extension: ASF) Audio extension of the format for streaming audio / video on the web.

Yamaha SoundVQ [Extension: VQF] Audio format released by Yamaha in direct competition with MP3.

Everything you need to know about audio files … compressed and uncompressed

Regardless of whether you’re listening to MP3 files or high-definition audio, it’s time to find out exactly which file format is best for your needs.

As you organize your digital music collection, you may be impressed by the number of different audio file formats you have collected over the years. For this reason (and since a good review doesn’t hurt anyone) we’d like to deepen the discussion of the most common audio file formats, explain the differences and explain why you should be interested in learning more about them. Whether you’re listening to low quality MP3 files, slightly better AAC tracks, or high definition audio in FLAC or WAV, it’s time to find out exactly what you’re dealing with and which file format best suits your needs.

File formats and codecs

Below is a list of all common audio file formats and the differences between them.

-AAC (no high resolution): Apple’s alternative to MP3. It’s a compressed audio format, but it sounds better than MP3 and is used to download music from iTunes and stream via Apple Music.

-AIFF (high resolution): Apple’s alternative to WAV, but with better metadata support. It’s an uncompressed and lossless format, but it’s not very popular.

-DSD (High Resolution) – The uncompressed single bit format for super audio CDs. It is available in the 2.8 MHz, 5.6 MHz and 11.2 MHz variants, but due to its high-quality codec it is (currently) not suitable for streaming.

-FLAC (High Resolution) – This lossless compression format supports high-resolution sampling rates, takes up about half the WAV space, and stores metadata. It is license-free and is the preferred format for downloading and storing albums in high resolution or CD quality. The disadvantage is that it is not compatible with Apple (therefore it is not compatible with iTunes).

-MP3 (not high definition): Lossy, compressed format that guarantees small file sizes, but is far from the best possible audio quality. However, it is still very convenient for storing music on smartphones and other mobile devices and is widely used.

-MQA (High Resolution) – A lossless compression format with high resolution files for more efficient transmission. It is used for high-resolution streaming from Tidal Masters and other similar services.

-OGG (not high resolution): Sometimes you can find him by his full name, Ogg Vorbis. An open source and compressed alternative to MP3 and AAC that is not limited by patents. This format is used (at 320 kbit / s) to stream Spotify.

-WAV (High Resolution) – The standard format in which all audio CDs are encoded. Excellent sound quality and no compression, which means large files (especially for high-resolution files). However, metadata (album art, artist information, and song title) are hardly supported.

-WMA Lossless – An uncompressed embodiment of Windows Media Audio, but is no longer supported by smartphones or tablets.

The 10 most common audio formats: which one to use?

Audio files are available in all types and sizes. And although we are all familiar with MP3, what do you think of AAC, FLAC, OGG or WMA? Why are there so many audio standards? Which are important and which to ignore?

It’s actually quite easy to find that all audio formats fall into three main categories. Once you know what the categories mean, you can simply choose a format within the category that best suits your needs.

Uncompressed audio formats

Uncompressed audio consists of actual sound waves that have been captured without further processing and converted into a digital format. As a result, uncompressed audio files are usually the most accurate, but take up a lot of space, about 34MB per minute for 96-bit and 96-bit stereo.

Audio file format: PCM

PCM stands for Pulse Code Modulation, a digital representation of analog audio signals. Analog tones exist as waveforms, and in order to convert a waveform into digital bits, the tone must be sampled and recorded at certain intervals (or pulses).

This digital audio format has a “sample rate” (how often a sample is taken) and a “bit depth” (how many bits are used to represent each sample). No compression is required. The digital recording is an almost exact representation of the analog sound.

PCM is the most common audio format used on CD and DVD. There is a PCM subtype called Linear Pulse Code Modulation, in which samples are taken at linear intervals. LPCM is the most common form of PCM, so the two terms are almost interchangeable at this point.

Audio file format: WAV

WAV stands for Waveform Audio File Format (at some point also called Audio for Windows, but no longer). It is a standard developed by Microsoft and IBM in 1991.

Many people believe that all WAV files are uncompressed audio files, but that’s not exactly true. WAV is actually a Windows container for various audio formats. This means that a WAV file may contain compressed audio, but this is rarely used.

Most WAV files contain uncompressed audio in PCM format. The WAV file is just a container for PCM encoding, so it is more suitable for use on Windows systems. However, Mac systems can generally open WAV files with ease.

Audio file format: AIFF

AIFF stands for Audio Interchange File Format. Similar to how Microsoft and IBM developed WAV for Windows, AIFF is a format developed by Apple for Mac systems in 1988.

Similar to WAV files, AIFF files can contain several types of audio formats. For example, there is a compressed version called AIFF-C and another version called Apple Loops that is used by GarageBand and Logic Audio. Both use the same AIFF extension.

Most AIFF files contain uncompressed audio in PCM format. The AIFF file is just a container for PCM encoding, making it more suitable for use on Mac systems. However, Windows systems can generally open AIFF files with ease.

Lossy compression audio formats.

Lossy compression occurs when some data is lost during the compression process. Compression is important because uncompressed audio takes up a lot of space.

In other words, lossy compression means that the sound quality and fidelity for smaller files are affected. If you are hurt, you will hear artifacts and other oddities in the audio. But if done correctly, you won’t feel the difference.

Audio file format: MP3

MP3 stands for MPEG-1 Audio Layer 3. It was released in 1993 and is becoming increasingly popular. It is the world’s most popular audio format for music files. There is a reason why we had “MP3 players” but no “OGG players”!

The main purpose of MP3 is in three ways: 1) removing all audio that is out of the normal human hearing range, and 2) reducing the quality of inaudible sounds, then 3) compressing all the other audio as efficiently as possible.

Almost every digital device in the world with audio playback can read and play MP3 files, be it PC, Mac, Android, iPhone, Smart TV or anything else. If you need a universal device, MP3 will never disappoint you.

Note: MP3 is not the same as MP4!

Audio file format: AAC

AAC stands for Advanced Audio Coding. It was developed in 1997 as the successor to MP3 and although it has become popular as a format to be used, it has never surpassed MP3 as the most popular.

The compression algorithm used by AAC is much more advanced and technical than MP3. So if you compare the same recording in MP3 and AAC format with the same bit rates, the AAC generally has better audio quality.

Although MP3 is a more popular format, AAC is still widely used today. In fact, this is the standard audio compression method used by YouTube, Android, iOS, iTunes, later Nintendo laptops, and later PlayStation.

Audio file format: OGG (Vorbis)

OGG represents nothing. In fact, it’s not even a compression format. OGG is a multimedia container that can contain all types of compression formats. However, Vorbis files are most commonly used. Therefore, these audio files are called Ogg Vorbis files.

Vorbis was first released in 2000 and is growing in popularity for two reasons: 1) it conforms to the principles of open source software and 2) it works significantly better than most other lossy compression formats (ie) this results in a smaller file size for an equivalent sound quality.

MP3 and AAC are so strong that OGG struggles to get into the spotlight – not many devices support them natively, but they do improve over time. It is currently used primarily by supporters of hardcore open source software.

Audio file format: WMA (lossy)

WMA stands for Windows Media Audio. It was first published in 1999 and has gone through several developments since then, always keeping the same name and WMA extension. It is a proprietary format created by Microsoft.

Similar to AAC and OGG, WMA should fix some of the errors in the MP3 compression method, and it turns out that WMA’s approach to compression is very similar to that of AAC and OGG. Yes, in terms of the quality of objective compression, WMA is really better than MP3.

However, since WMA is proprietary, it is not supported by many devices and platforms. In addition, it offers no real advantage over AAC or OGG. If MP3 is not good enough, it is only more practical to use one instead of WMA.

Audio formats with lossless compression.

The opposite lossy compression is lossless compression, in which the size of an audio file is reduced without loss of data between the source audio file and the compressed audio file.

The disadvantage is that lossless compressed audio files are larger than lossy compressed audio files, up to 2 times 5 times larger for the same source file.

Audio file format: FLAC

FLAC is an abbreviation for Free Lossless Audio Codec. Maybe a bit on the nose, but it has quickly become one of the most popular lossless formats since its launch in 2001.

The good news is that FLAC can compress an original source file by up to 60 percent without losing a single bit of data. What’s even better is that FLAC is a free, open source audio file format, so there are no intellectual property restrictions.

FLAC is compatible with most major programs and devices and is the primary alternative to MP3 for music. You basically get the full quality of uncompressed audio with half the file size. That is why many see FLAC as the best audio format.

Audio file format: ALAC

ALAC stands for Apple Lossless Audio Codec. It was developed and published as a proprietary format in 2004, but became open source and copyright-free in 2011. ALAC is sometimes referred to as Apple Lossless.

While ALAC is good, it is somewhat less efficient than FLAC in terms of compression. However, Apple users cannot choose between the two, as iTunes and iOS offer native support for ALAC and no support for FLAC.

Audio file format: WMA (lossless)

WMA stands for Windows Media Audio. We already discussed this in the lossy compression section, but we explained this here because there is a lossless alternative called WMA Lossless that uses the same extension. Confused, I know.

Compared to FLAC and ALAC, WMA Lossless is the worst compression efficiency, but not much. Since it is a proprietary format, it is not suitable for open source software enthusiasts, but is natively supported on Windows and Mac systems.

The most used audio formats

As you can imagine, when we talk about digital formats in the field of sound, the range is wide. When choosing the one that best suits our needs, we need to think about several questions. To do this, the first thing to do is to know the most used audio formats.

We start by clarifying the concepts of bit depth and sample rate, which are essential for understanding how audio formats work. These are two measurements that indicate the quality of a digital audio file.

When we read the specifications for audio formats and find, for example, 32 bit / 192 kHz and 24 bit / 96 kHz, these figures refer to “bit depth” and “sampling frequency”, respectively. They tell us the amount of information transmitted by the different formats and the quality of the sound. The more times a device reads samples, the higher the quality.

Audio formats

-MP3: These files weigh very little for any device to read. The downside is that the quality of compression is sacrificed.

-WAV (Waveform Audio File Format): These are higher resolution files than MP3, an audio track which is coded with what is called Pulse Code Modulation (PCM). Analog audio tracks are encoded and converted to digital so that they can have sample rates and bit depth.

-AIFF (Audio Interchange File Format): it is very similar to WAV and also uses PCM to encode analog audio tracks and present them in digital format. Indeed, AIFF and WAV files are more or less interchangeable.
In short, when we talk about a file in WAV or AIFF audio format, we are talking about a good quality piece of sound.

What audio formats are there? All you need to know

FLAC, WAV, AIFF, DSD … these are just some of the initials that you can find when you are looking for a digital format. They are also accompanied by technical data such as sample rates and bit depth. So many terms can leave you more misplaced than a chicken at a dance. And it is that unless you are an expert in digital sound, the process to choose the audio format that best suits your needs can be a mess. But if they explain it to you, the topic is relatively simple. That is why at Culturasonora we have prepared a complete guide for you on the different audio formats most used. This will prevent any acronym from taking you on the dark side.

What are Bit Depth and Sample Rate?

These two concepts are basic. To understand how audio formats work you need to know what Bit Depth and Sample Rate are. These are two measures that indicate the quality of a digital audio file. We are going to try to summarize it so that you keep the general idea

samplerate

When you read the specifications of the audio formats you come across a couple of figures. For example: 32-bit / 192kHz or 24-bit / 96kHz. These numbers indicate the bit depth and the sample rate. These references tell us how much information the different formats transmit and the quality of the sound. For example, the audio we hear on a regular CD, or on a Spotify stream, is 16bit / 44.1kHz. Samples are always measured in Hertz (or hertz) and bit depth in Bits.

Softwares or hardwares usually do not work with a continuous flow of information, but usually use pieces, samples or samples to effectively manage the data that is transmitted. The sample rate is the number of samples per second that are obtained from a recording. The higher the number of times a device plays samples, the higher the sound quality. Each of these extracts or samples has a certain amount of information, which is the bit depth, or bit depth.

So that you understand it better we are going to make a somewhat beastly analogy, which is not entirely true, but that will help you get the sense of all this. Which is what interests us. If you control a bit of photography and image you will get it right away: the sample rate would be something similar to the frames or frames per second of a video, and the bit rate would be similar to the pixels of a photograph. The higher the bit depth number, the more information each sample will have. The more pixels an image has, the higher resolution each frame of a video will have. The more frames per second a movie has, the better definition. In short: the higher the number of the Bit Depth and the Sample Rate, the higher the quality of the audio file. Heard cooking?

Audio formats: MP3 vs WAV vs AIFF

What is the MP3 format?

If you’re interested in getting some audio fidelity and decent sound from your files, you’ll want to avoid this format. Why? Because basically an MP3 is a file that sacrifices audio quality to minimize size. They weigh very little for any device to read. The negative? Compressing these files provides poor, almost lifeless sound. Today, hardly anyone uses this format seriously. Even its creators recently ended the license by declaring it dead. But surely from time to time you come across a zombie file with this format.

What is WAV format?

WAVs (Waveform Audio File Format) are just as common but better for anyone who wants a decent audio format. They are higher resolution files than MP3s. A WAV is an audio piece that is encoded with something known as Pulse Code Modulation (PCM), a medium that encodes analog audio pieces and converts them to digital so they can have the Sample rate and Bit Depth of the that we have already talked about previously.

What is the AIFF format?

The AIFF (Audio Interchange File Format) audio format is very similar to WAV in that it also uses PCM to encode analog audio pieces and present them in digital format. This format was born as a response from Apple to Microsoft’s WAV, and at the beginning it could only work on MAC computers. Currently AIFF and WAV are more or less interchangeable.
In summary…
To close this topic, we will tell you that if you have a file in WAV or AIFF audio formats, you will hear a piece of sound of good quality. Normally these formats are used in files that we reproduce through our services, such as the iTunes music library. We will not see them in online streaming services, which tend to use special types of files.

Audio Formats: Know all that exist

There are several kinds or types of audio formats, you probably know the most common ones such as mp3, mp4, wav, etc. In this article you will know which are the most important apart from those mentioned above and how they differ from each other.

What is an audio format?

An audio format is a multimedia container where data is stored in an audio file. Each of these has its own characteristics and capabilities in terms of reproduction, they also have a sample rate (bit rate) and a specific bit depth (bit depth) that are closely related to the quality of each format.

Let’s talk about the sample rate and the bit depth
These two terms refer to the way it is stored and how an audio file is played. For this, what is sought is to digitally re-interpret the analog signal of a recording. As they have a type of continuous analog wave signal and instead the digital language used by computers is given by shorter and more concrete actions (1 and 0) executed at high speed, that continuous analog wave must be described in more values Small and concrete.

To achieve this conversion, small fragments of a specific size of the analog signal are taken, each sample (sample) contains the necessary information so that by putting all the “pieces” together and reproducing them in the same order and at the same speed in which they were captured, as a result a reliable digital interpretation of analog recording.

The frequency at which each of these samples is reproduced is what is called “sampling rate” or “sample rate” and the digital data in bits contained in each sample is called “bit depth” or “bit depth ”.

How is an audio format different from a codec?
The difference between these two is that while a codec as its name says is responsible for encoding and decoding all the information in an audio file, the format gives us the idea of how this audio information is stored, what is its bit depth, its sample rate, etc.

Types of audio formats

Among the types of audio formats there is a large amount and we will separate them into 4 groups or families to understand a little better the characteristics and potential they have:

1.Compressed audio format

The uncompressed formats allow several sample rate combinations in a flexible way and seek to preserve all the details of the analog recording even the details inaudible to our ears.

The main ones are:

WAV

Owned by IBM and Microsoft, the Wave Audio File Format was developed by these two previous ones to store sounds on the PC or computer. It is relatively similar to the Mac AIFF and a variant of the RIFF or Resource Interchange File Format which is a file format for the exchange of resources.

AIFF

The Audio Interchange File Format was co-developed by Apple Inc. to store sound data on personal computers. The AIFF is used professionally for audio applications along with SDII and WAV because it is a compression-free format and fast signal processing

This format was formerly common on internet pages. At first it was encoded in 8-bit data with a sample rate of 8000 Hz, uploading in the newer files to a 32-bit encoding.

2. Compressed audio format without loss or lossless
Because the uncompressed formats encode both the sound of a recording and the silences, a few seconds of sound from an audio file will weigh the same as the same seconds of silence. The type of lossless format compresses the file so that silence does not take up almost anything in size.

Between them we have:

Shorten

The SHN format is used for lossless compression of CD quality audio files, it is similar to formats such as RAR or ZIP with the difference that it is optimized for compression of audio data.

WMA Lossless

The WMA or Windows Media Audio format is a compressed audio format which has 4 codecs of which the WMA Lossless codec allows the compression of an audio file without loss of definition.

Within the codecs for this type of audio we have:
TTA

The True Audio Codec Compresses audio in 8, 16, or 24 lossless bits that are stored in WAV format files, which is done while maintaining good operating speed.

ATRAC

Although the first version of the ATRAC codec (Adaptive Transform Acoustic Coding) was developed as a lost audio encoder, currently the most recent version of this codec (ATRAC3) in addition to doubling the compression capacity of the first version is capable of encoding the An audio file with very few losses.
