Analog Tape Restoration
Upload audio digitized from a degraded analog master (soundtrack cue, film master, etc.) and restore it toward studio quality:
- De-click / de-pop — removes splice pops, dirt, dropouts
- De-hum — removes 50/60 Hz mains hum and harmonics
- De-hiss — spectral-gating broadband noise reduction, ideally profiled from an actual noise-only region of the tape
- Wow/flutter smoothing — mild envelope-based warble reduction (not a substitute for dedicated pitch-correction tools on severe cases)
- EQ restoration — rebuilds lost highs/lows from tape rolloff
- Dynamics restoration — gentle expansion + limiting to restore punch
For the best noise reduction, mark 1–2 seconds of pure hiss/room tone (no music) from the head or tail of the reel using the noise-sample controls.
Long files are slow on free CPU hardware; this Space caps input at 20
minutes. For longer masters, run tape_restore.py locally — see the
docstring at the top of that file for CLI usage.
