Free mastering
Free song mastering you can actually judge before paying
Free mastering usually means a 30-second snippet, a watermark, or a lower bitrate. Here the free master is the real one: full length, full quality, with the same engine and the same settings you would export.
Desktop recommended · phones work for listening and quick edits, but the full console, meters and fastest renders are on a laptop or computer.

Why it can be free
The mastering chain runs in your browser using your own CPU, so there is no render queue and no per-song server cost on our side. That means unlimited free attempts at full quality — no credits burned on versions you end up rejecting.
What you hear before paying
The complete master: corrective EQ, multiband dynamics, tonal shaping, stereo imaging, and a true-peak limiter, measured against the loudness target you choose. You also get the full report — integrated LUFS, short-term loudness, loudness range, true peak, crest factor — plus the quality-check pass for harshness and over-compression.
Free mastering vs paid services
Paid services typically charge per track or per month before you can hear the full result, and many still hand back a single fixed curve. Compare the trade-offs in our guide to AI mixing and mastering services, then decide with your ears rather than a preview clip.
