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.
MP3 is the most common music (sound) file format. This format was developed by Fraunhofer IIS and Thomson. This format for storing and transmitting music (sound) files in digital form uses signal compression technology. That is why, unlike the previously widespread WAV format, MP3 files (full name - MPEG Audio Layer-3) are much smaller in size, and their sound quality is much higher. The MP3 format was one of the first and most successful sound compression methods. One of the important characteristics of this process is the degree of compression, that is, how much data is transferred per unit of time. Standard MP3 encoding is from 64 to 320 kb / s.
