Analog Tape Restoration

Upload audio digitized from a degraded analog master (soundtrack cue, film master, etc.) and restore it: de-click, de-hum, de-hiss, EQ rebuild, and gentle dynamics restoration.

Tip: for the biggest quality gain, mark a 1–2 second region of pure tape hiss / room tone (no music) below — usually found at the very head or tail of the reel — so de-hiss learns this tape's actual noise floor instead of guessing.

Long files run slowly on free CPU hardware; this demo caps input at 20 minutes. For longer reels, run tape_restore.py locally.
