Most AI mastering tools are a black box: you get a louder file back and no idea what changed. LuvLang runs a disclosed 24-stage chain (console emulation, linear-phase EQ, multiband compression, M/S processing, ML stem separation) and shows the real BS.1770-4 LUFS, true-peak, and dynamic range numbers on every master, not a vague loudness slider. Full A/B preview against your original mix before you pay anything. Single tracks start at $14.99, no subscription, no royalties.
