| # 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. |
