MediaMonkey 3.x supports AAC playback if Quicktime is installed, though AAC encoding must be 

purchased as a separate option. It will play and tag all AAC audio files, and convert and analyze 

all AAC tracks that don't have DRM (i.e. .m4p files cannot be converted or analyzed). AAC 

playback in MediaMonkey 3 can fail if you've performed an upgrade from MediaMonkey 2.x to 

MediaMonkey 3.x, and the AAC plugins installed for MediaMonkey 2.x have not been removed

--these may interfere with the native AAC plugins included with MediaMonkey 3.x.



MediaMonkey 2.5 does not include AAC support at all, though playback support can be added 

through the use of third-party plug-ins. This support is available using the following plug-ins:

 1. MP4 input plugin. This supports unprotected .m4a and .mp4 files and can be downloaded from:

 2. Winamp MP3/MP4 input plug-ins. The MP4 plugin supports unprotected .m4a and .mp4 files

     and is included with Winamp 5 and can be copied to the MediaMonkey plug-ins directory

     (both libmp4v2.dll and in_mp4.dll must be copied). The MP3 plug-in supports AAC files.
