  • Transcoding in Subsonic is a way to re-encode music on the fly to a format your listening device supports. A common use is transcoding FLAC, WMA, and Vorbis audio to MP3 for devices supporting only that codec.
  • Configuring transcoding uses up to three commands one would use on a normal command line pipe but with a whitelist of executables installed or linked into /var/subsonic/transcode. The transcoding configuration page takes transcoding rules in the form of:

    • [rule name] [convert from] [convert to] [command 1] [command 2] [command 3]
      

  • The most compatible single audio transcoding command is with FFmpeg, transcoding any input to MP3, mapping all streams to output, and limiting metadata to the more-compatible ID3v2.3:

    • [All to MP3] [ogg flac wma aiff m4a] [mp3] ...
      [ffmpeg -i %s -ab %bk -id3v2_version 3 -map_metadata 0 -map 0:0 -ar 44100 -ac 2 -v 0 -f mp3 -]
      

  • You can also transcode with multiple single-codec commands to avoid the heavy [[FFmpeg]] dependency:

    • [FLAC to MP3] [flac] [mp3] ...
      [flac --silent --decode --stdout %s] [lame --silent -h -b %b -]
      

      [AAC to MP3] [m4a] [mp3] ...
      [faad -s -o - %s] [lame --silent -h -b %b -]
      

    • [Vorbis to MP3] [ogg] [mp3] ...
      [oggdec -Q -o /dev/stdout %s] [lame --silent -h -b %b -]
      

    • [MPC to MP3] [mpc] [mp3] ...
      [mpcdec %s -] [lame --silent -h -b %b -]
      

      [APE to MP3] [ape] [mp3] ...
      [mac %s - -d] [lame --silent -h -b %b -]
      

    • [Trackers to MP3] [mod s3m xm it] [mp3] ...
