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
