  • Normalize audio data
  • Apply Fade In/Out effects

  • Split files
  • Reduce pauses
  • Edit or create tags for audio files (Batch tag editor)
  • Create file names using tag information (MP3 and others) or sequential numbers
  • Change playback speed
  • Perform additional processing supported by add-ons
