Shift SRT or WebVTT captions to a likely speech onset or by a manual offset.
audio-caption-timing-shifterMedia
Compare SRT or WebVTT cue timing with likely speech activity and flag timing drift.

Validate concatenated audio files for errors and inconsistencies
audio-concat-validatorMedia
Compare two audio files and show their differences
audio-diffMedia
Remove clicks and pops from audio files caused by vinyl records, digital errors, or other impulsive noise sources
audio-declickMedia
Repair clipped audio by reconstructing peaks that exceeded the maximum amplitude. Restore distorted audio from overdriven recordings or excessive gain
audio-declipMedia
Remove crackles and subtle impulsive noise from audio files. Ideal for restoring old recordings, cassette tapes, and digitized vinyl with surface noise
audio-decrackleMedia
Compute dynamic range via crest factor (peak minus RMS)
