Every feature is built around two principles: protect the mix first, push loudness second.
Separate Vocals, Drums, Bass and Other server-side, then EQ and balance each stem before the master chain. Fair-use 120 min/month.
Right-click adds a band, drag to tune. Live spectrum analyzer. What you hear in the browser is what the server renders.
Two-pass loudnorm + dedicated true-peak limiter with 4× oversampling. Ceiling enforced per mode (−1 dBTP streaming, −2 dBTP loud modes) — no inter-sample clipping on streaming re-encodes.
Balanced Streaming, Dynamic, Commercial, Voice, Apple Streaming, TikTok/Reels, Club/DJ, and Vinyl — each with mastering-safe clamps on compressor, limiter and saturation.
Post-render analysis flags over-compressed sources, aggressive references, limiter pumping and low-quality stems — with plain-language fixes.
Auto-detect target genre, pick a preset, or upload your own reference track. Genre-mismatch detection prevents bad matches.
Detects AI artifacts (frequency ceiling, crushed dynamics, hot peaks), never boosts the empty band above the ceiling and guarantees streaming-safe true peaks. What mastering can't fix is reported honestly.
−14 LUFS streaming · −16 LUFS dynamic · −10 LUFS commercial — true peak −1 dBTP (streaming) / −2 dBTP (loud modes).
