  • csvc - changing the speed for video file or for cuts in video file during reencoding. A demonstration of the work of this script can be found in the playlist, except for the first video from the playlist.

Audio streams in video files
  • fdrc - "force dynamic range compression" makes the sound of video files in the format *.mkv or *.mp4 louder, but not an equivalent to sources, so it suitable for movies and cartoons, but not for concerts and music. This is best used for stereo channels or downmix to stereo. Video demonstration

  • fdrch or fdrch+ - "Force Dynamic Range Compression to center cHannel" makes the sound of video files in the format *.mkv louder. This is best used for multichannel audio streams with a center channel (FC) Demonstration

Audio
  • nit - "normalize it" - bash script that normalize the volume of audio files

  • cuesplit - Splitting one audio into separate flac files corresponding to the CUE

  • tempo - shell script that allow to "overclock" or "underclock" speed of audio files

msslib - all previous scripts in single file (+ new function - 'lca' - add a local cover art to mp3, flac or mka)

More simpler scripts:

  • normnconv - normalize audio/music during convert it to *.ogg

  • f2fn (fvn) - normalize and recompress flac to flac, equivalent but louder if possible.
