Free AI mixing and mastering — hear the whole thing before you pay
MixTrackLab runs the full mix and master in your browser at no cost. You get the finished result, loudness-matched A/B against your original, and every meter and report. Payment only happens if you decide to export the file.
Desktop recommended · phones work for listening and quick edits, but the full console, meters and fastest renders are on a laptop or computer.

Why the preview is free
The engine runs locally in your browser, so there is no render queue and no server cost per song. That means we can let you mix and master as many versions as you want, at full quality, and charge only for the export. No credits burned on failed attempts, no upload waiting, no watermarked previews.
What you get before paying anything
The complete mix: vocal cleanup (noise, plosives, sibilance, breaths), key-aware pitch correction, per-stem EQ and dynamics, frequency carving, ducking, and bus glue. Then a full master with your chosen signature, measured against a loudness target, with true peak safety and a quality-check pass for harshness and over-compression.
Free vs paid AI mastering services
Most online services let you hear a low-quality or shortened preview, then charge per track or per month before you can hear the real thing. Here the audio you hear is the audio you export — same engine, same settings, full length. Compare the options in our guide to the best AI mixing and mastering services.
