APE is a sound file format. In this format, data encoding is performed using Monkey's Audio Lossless. The developer is Matthew T. Ashland of Monkey's Audio. Compression of audio data in this format occurs without loss of quality. The sound quality of APE files is much higher (corresponds to high-end WAV and WAVE formats) than the more common and popular MP3 files, but they take up more space. The software package Adobe Audition allows you to edit the soundtracks of APE files. The format supports the ability to correct write errors.
FLAC is a free cross-platform audio codec format created in 2001 by Josh Colson and Xiph.Org. The name of the format is an abbreviation of the English phrase Free Lossless Audio Codec. When compressing a file into the FLAC format, it is 50-60% of the original file without loss of sound quality (especially when working with voice recordings). When unpacking such a file, absolute originality is respected. Since the format is free and open, it is supported by almost any software, it is perfect for archiving files and for regular listening to digital recordings.
