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.
AC3 is a sound file format. Its name is the abbreviation for Audio Codec 3. The format was developed by Dolby Laboratories, Inc as a modern and efficient sound compression technology. AC3 files feature Dolby Digital multi-channel surround sound. In this regard, they are widely distributed as a format for DVDs, movie theaters and game consoles. However, you can evaluate all the advantages of such files only if you have the appropriate acoustics for surround sound. An audio file of the specified format can include up to six sound channels, which creates a presence effect for the listener.
