1. The most common high-definition music formats are APE, WAV, FLAC, etc. These are all lossless compression formats, and APE is becoming more and more popular at present.

2. The differences between APE, WAV and FLAC:

1. Different developers:

ape: APE is suppressed by the software Monkey's audio, and the developer is Matthew T. Ashland, open source, famous for its "monkey" logo on the interface.

FLAC: The FLAC project was started in 2000 by Josh Coalson. After entering the beta phase and releasing the reference implementation of version 0.5 on January 15, 2001, the FLAC bitstream format was frozen.

WAV: WAV is a sound file format developed by Microsoft. It conforms to the RIFF (Resource Interchange File Format) file specification

2. Different compression rates:

ape: APE has a better compression rate

FLAC: FLAC’s compression rate is slightly inferior

WAV: mono amplitude data is n*1 matrix points , the stereo is n*2 matrix points, and the sampling frequencies are generally 11025Hz (11kHz), 22050Hz (22kHz) and 44100Hz (44kHz).

3. Different support platforms:

ape: APE format, currently only officially supports Windows.

FLAC: FLAC is currently the only lossless compression encoding that is widely supported by hardware. In the consumer field, many mobile multimedia players, cars, and home audio equipment already support the FLAC format.

WAV: Widely supported by Windows platforms and their applications, this format also supports multiple compression algorithms such as MSADPCM, CCITT A LAW, etc., and supports a variety of audio numbers, sampling frequencies and channels

4. Different open source properties:

ape: APE is a personal work, and copyright issues may arise in the future; its technical level and support are inferior to FLAC, an internationally accepted standard format.

FLAC: FLAC is an open source and completely free lossless audio coding and compression format. It is an international standard. Compressing with FLAC will not lose any information of PCM audio.

WAV: It is a proprietary format of Microsoft Corporation and is mainly used for Microsoft systems.

5. Different fault tolerance rates:

ape: APE files have poor fault tolerance. As long as there is a slight error during the transmission process, the entire APE music will be invalid.

FLAC: FLAC file because there is no correlation between each frame of data. Therefore, when the FLAC file is damaged during the transmission process, resulting in the loss of data in a certain frame, only the audio information of that frame will be lost, and the data before and after will not be affected.

WAV: Capacity occupied by WAV format files (B) = (sampling frequency It is 10MB, and its size does not change with changes in volume and clarity.

WAV is the closest to lossless music format, so the file size is relatively large.
