Want to archive a CD collection at full quality while saving disk space? The free Monkey’s Audio compresses digital music into APE files while preserving the audio data, so the files can be decompressed back to their original form.
APE compression and restoration
The central workflow is to compress digital music into Monkey’s Audio files, then decompress those files when the original audio is needed. The compression is lossless: it does not discard audio data to reduce file size. This makes the format suitable for archiving music while retaining the ability to recreate the source files.
Monkey’s Audio can also recreate the original music CD files from its compressed copies. That gives collectors a way to store compressed versions and restore the source audio without recopying the CD.
How does Monkey’s Audio protect compressed files?
The program uses redundant CRCs, a form of error checking, to verify that data decompresses properly. Errors do not go unnoticed, which is important when keeping compressed music as an archive.
APE Tags provide fields for managing and cataloging a Monkey’s Audio collection. They let users keep identifying information with the files as the library grows.
Playback and encoding connections
Monkey’s Audio files are supported by several popular music players and ripping programs, including Foobar, Windows Media Player, and Winamp. It can also act as a front end for external encoders.
