Version 3.0 — Bigger, Louder, Smarter
We rebuilt the entire mastering engine. Your podcasts now hit real broadcast-loudness targets, sound cleaner, and have AI noise reduction one click away.
- Spotify-spec loudness (-14 LUFS targeting, not just reference matching)
- AI noise reduction toggle — cleans hum, room tone, hiss
- All-new polish chain: de-esser, presence lift, leveling compressor
- True-peak limiting at -1 dBTP (no more clipped uploads)
- Iterative loudness convergence (hits target within 0.3 dB)
- Fixed the inverted loudness modes — "Loud" is now actually loud
