> Most AI mastering tools take one mixed file and apply a one-size-fits-all chain — they can't tell vocals from drums, so they over-compress the vocal trying to control the kick. OneMaster is stem-aware: upload beat and vocal as separate channels, and the AI enhances each independently (de-essing vocals, prepping beats), then sums and runs a 3-pass loudness chain calibrated to Spotify/Apple delivery specs (-9 LUFS, -1 dBTP, 24-bit). 10s delivery, 5 free previews, $15/song.
