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
