MediaMonkey (no connection with Monkey's Audio, the lossless audio codec), made by Ventis Media Inc, is an audio player that also functions as a media library. It maintains its library in a database that is compatible with Microsoft's Access database format, and as such, the database entries can be changed by using Access or other compatible programs.

MediaMonkey is extensible using script-based code, giving users access to new functionality and creating the possibility of extending the program themselves. Using this interface one could access almost any aspect of MediaMonkey's organizational capabilities via an external application - or script - that can be fully integrated with MediaMonkey.

Music formats that MediaMonkey supports are OGG, MP3, WMA, WAV, APE, FLAC and MPC. Music can be ripped from Audio CDs and converted between most of these formats. MediaMonkey includes a multi-format tag editor that can save to a variety of tag formats for the files it supports, including: ID3v1 and v2, Ogg comments, WMA, APE2, and WAV tags. It also handles automatic and "intelligent" tagging of files based on filenames through use of the Auto-Tagger.

Support for portable audio devices allows one button synchronisation to synchronise tracks and playlists with a broad range of portable devices including the iPod, iriver H300 series, Sony Ericsson W800i and PlaysForSure devices.
