MasterMe will listen like an engineer, then explain — in plain English — exactly what it hears and what to do about it, and why.
MasterMe runs entirely in your browser — your audio is never uploaded. Real DSP via the Web Audio API · loudness measured to ITU-R BS.1770.
Neural stem separation (HTDemucs) is the cloud-GPU phase of the roadmap; this build teaches with real-time band analysis.
