This is from WinRar help:

Archiving options/Use multimedia compression

   Enables a special multimedia compression algorithm. This is intended to be used primarily when compressing raw digital audio data such as WAV's up to four 8-bit or two 16-bit channels, but also shows good results with true color (24-bit) bitmaps. An improvement in the compression ratio, of up to 30%, may be expected over normal compression. Multimedia compression can be used only with RAR archives.
   During archiving of a file, in multimedia mode, RAR performs intelligent data analysis and may use the general or multimedia compression algorithm for different parts of the file depending upon which algorithm is the more suitable. Such analysis allows optimum performance when different data types exist in the same file (This is typical for STM and MOD files).

   If this option is used with data which are not multimedia, the compression ratio, generally, will not be changed but, due to the multimedia analysis overhead, speed is always decreased. So it is not recommended to use -mm with data other than multimedia data. Multimedia compression is designed only for a certain file types. E.g. it works well with WAV, STM, MOD and true color bitmaps, but will gain nothing for MID, GIF, JPG or 8-bit bitmaps.
