lossless music

Lossless music is a kind of music file playback format, which is divided into two types: lossy compression and lossless compression.

However, due to data loss in the audio digitizing process, it is actually impossible to achieve true lossless.

type of sound
Commonly seen MP3, WMA, and OGG are called lossy compression. As the name implies, lossy compression reduces the audio sample rate and bitrate, and the output audio file will be smaller than the original file. . Another audio compression is called lossless compression, which can compress the volume of the audio file to a smaller size on the premise of saving 100% of all the data in the original file. Same size, same bitrate. Lossless compression formats include APE, FLAC, WavPack, LPAC, WMALossless, AppleLossless, TTA, Tak, TAC, La, OptimFROG, Shorten, and common and conventional lossless compression formats include APE, FLAC, TTA, TAK.
General WAV CD can capture this music format. However, due to the high volume and uncompressed original audio, it can usually be compressed and converted to FLAC or APE at a lower volume. Note: wav is still a lossless format, and the last two are lossless compression formats

BOW
APE is one of the popular digital music file formats. APE is a lossless audio compression technology, that is, after compressing the audio data file read from the audio CD in APE format, you can restore the file in APE format, and the restored audio file is the same as the original. compressed audio file. Exactly the same as before, nothing to lose. [one]
FLAC
FLAC is short for Free Lossless Audio Codec [2] , which can be interpreted as Chinese lossless audio compression coding. FLAC is a well-known free audio compression codec, which is characterized by lossless compression. Unlike other lossy compression codes such as MP3 and AAC, it does not destroy any original audio information, so it can restore the sound quality of music discs. It has been supported by many software and hardware audio products since 2012.
FLAC is similar to MP3, but it has lossless compression, which means that the audio is compressed in FLAC without losing any information. This compression is similar to Zip, but FLAC will give you a higher compression ratio, because FLAC is a compression method specially designed for the characteristics of audio, and you can use the player to play FLAC compressed files like you normally play MP3 files (many Car players and home audio devices already support FLAC, and you can find links to the manufacturers of these devices on the FLAC website).
FLAC is free and is supported by most operating systems, including Windows, “unix” (Linux, BSD, Solaris, OSX, IRIX), BeOS, OS/2, and Amiga. And FLAC provides a build system in autotools, MSVC, Watcom C and ProjectBuilder development tools.
WAV

The WAV format is a sound file format developed by Microsoft, also known as a wave sound file. It is the first digital audio format and is widely supported by the Windows platform and its applications. The WAV format supports many compression algorithms, supports a variety of audio bits, sample rates, and channels. It adopts a sampling frequency of 44.1 kHz and a quantization number of 16 bits. Therefore, the sound quality of WAV is almost the same as that of CD, but WAV format requires too much storage space, it is very inconvenient to communicate and broadcast.
WAV’s full name is Wave Audio Files, and WAV is derived from sampling analog waveforms of sound. Sampling the analog waveform of sound with different sampling rates can obtain a series of discrete sample points, convert the values of these sample points into binary numbers with different quantization bits (8 bits or 16 bits), and then store them in the disc, this produces a WAV file of the sound, a wave file . Microsoft Sound System Sound Finder software can convert AIF , SND and VOD files to WAV format.
This format records the waveform of the sound, so as long as the sample rate sample rate

Digital Music: A Quick Guide to Having the Best Lossless Files

Digital Music

Surely changing our music from one side to the other, from an analog format to a digital one or even music already stored in digital format on a compact disc towards one for use on mobile devices, would result in a loss of sound quality that would exceed convenience and comfort.

This has been the main vision of people who care about sound quality, since the concept of digital music files was born. A reference generated by the common use of highly compressed lossy formats such as MP3.

wHowever, it is an opinion that simply “cannot take any more water.” Yes, popular formats like MP3 and AAC sacrifice some quality to keep file sizes small, but the emergence of lossless digital audio formats that are capable of preserving every piece of information from a CD recording means that a ripped file It may sound indistinguishable from the original.

You may still be wondering why you should spend precious time ripping up your CD collection. It’s all about convenience: a lossless digital music collection saves shelf space, is easy to move and to back up; for larger collections, it also makes locating individual songs and albums much easier and faster. You can also access a digital music library from multiple sources simultaneously, for example, from multiple network music players located in different rooms in your home.

Additionally, thanks to higher quality file acquisitions with popular streaming and download sites like B&W Society of Sound, higher quality music files can now be accessed as part of a subscription-based model without taking up space valuable on shelves – or even the attic – with physical means.

On the hardware side, storage devices like NAS and external hard drives offer huge amounts of space at ever lower prices. And with increasingly better and less expensive, widely available high-quality DACs, computers now offer excellent reproduction and can be easily connected to your existing hi-fi system, either wired or wireless.

When streaming or ripping discs, the file format option may seem complicated by too many options. This is what we think of the main formats that can be the salvation of true audio enthusiasts:

FLAC

Free Lossless Audio Codec is a popular choice for many audiophiles. Like MP3 and AAC, FLAC is compressed to keep file sizes relatively small, but unlike those formats, it is lossless and therefore – in theory – indistinguishable from the quality of a CD. In theory. Audio from CD converted to FLAC will typically shrink about 50 percent from its original size; a typical three-minute song on a CD will take up 30-40MB of space, while a ripped FLAC version of that song results in 15-20MB.

FLAC supports metadata (artist and song information can be embedded in the file and artwork can be referenced by the file) and will be played on a wide variety of software and hardware. Crucially for many, it is currently not compatible with Apple products like iTunes or the iPhone.

However, there are downsides to FLAC from an audiophile perspective and a lot of that comes during encoding and decompressing the file for playback. Because FLAC is unzipped on the fly, the sound quality is highly dependent on the software you are using to do that. Therefore, although it is theoretically lossless, there are still barriers to overcome when listening to the music contained in FLAC.

Apple Lossless

As you might guess from the name, Apple Lossless Audio Codec (or ALAC) was developed by Apple and works with company products like iTunes, iPod and iPhone (as well as supported by a number of other computers and players on software); If you are an avid user of the Apple team, it will be very attractive to you. However, like FLAC, this format is compressed, and files ripped from a CD are typically around 40-60 percent of their original size. Furthermore, ALAC suffers from the same decoding problems as FLAC.

AIFF

AIFF is a lossless format, but also without compression. While this means that it takes up as much space as the source file when ripping from a CD, it also avoids any compression issues, making it the ideal file for people who are concerned about sound quality.
