What is the highest quality music format right now? PART 2

CD discs

The audio CD format, or rather the .cda extension, appeared around the same time.

Unlike “wave” files saved on the hard disk, they cannot be edited. Today it can be opened in an audio processing program, reformatted by audio transcoding, and saved anywhere other than on a CD.

After specifying the output format and the device we will play them on, the conversion will begin. For all these tasks, we only need to drag and drop the elements that we are working with in its user interface. For example, if we are playing a file at twice the speed, an easy way to interpolate would be to play one sample out of two.

If you place the object at 50% pitch, you should double the number of samples, and an easy way to do this is to find the average of the two actual samples. Well, this signal needs to be decompressed, and this requires a proportionally higher CPU load that can “saturate”. And a less saturated processor means less risk of “hang.” We will analyze the most popular compression formats that will allow us to compress any file without losing information. What is fast? The most powerful?

MP3 codec
With the advent of the LAME MP3 Encoder codec, the music industry experienced a real shock, because those files “weighed” dozens of times less than the same WAV file. Even a five minute compose at full compression rarely exceeds the size of 5-7MB. Agree, a significant advance, not to mention the fact, allowed not only to adjust the above characteristics, but also some additional parameters in the form of ID3 tags, which contained information, for example, about the artist, album name and tracks. , the release date.

What is file compression? What does squeeze mean?
And the most used? Have you ever come across a file that was too busy and you didn’t know how to make it work less, like mail it to a friend? Compressing the file allows us to reduce the size of the file. It will take up less space on your hard drive and it will be easier to send. Depending on the type of file used and the type of compression, its size will be reduced more or less.

What compression formats are there and which are the most popular?
As we just said, there are several types of compression methods. For example, it is a compression method used to compress video, audio, or image files. The main characteristic of this compression method is that by compressing approximations, the media file is reduced in size. This method looks for repeating patterns in addition to other more advanced methods. This is achieved by reducing the file size without loss of information or quality, although obviously the file size is not reduced. Unlike the previous case, this information is not lost. … When it comes to compression formats and methods, we have a wide range.

This type has become the most popular. Look, almost the entire Internet is full of this universal format. In general, we can say that the MP3 audio format has become a true revolution in sound. It remains one of the most popular and in-demand so far, even though it is being replaced by other types of audio. But more on that later.

Introduction
As always, I’ll start with the senile complaints. Twenty years ago … In fact, twenty years ago there was no particular option. Because there were CDs that were turned into WAV files that took up the space of an average “hard drive”, well, there was quite a bit of space left in the operating system. And on the BBS. And the games. And in the archive of files. And that’s it. Because the average size of a hard drive back then was a whopping 850 megabytes today. Yes, exactly that 850, and exactly one megabyte. The impetus for everything was given by the appearance of the MP3 format in 1997, and it was a very significant year!

What is the highest quality music format right now?

The first audio format in computer games

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.

Advanced Audio Formats Part 2

DTS

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.

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.

Advanced Audio Formats

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.

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.
