How to Master a Song Online

Turn a finished mix into a balanced, release-ready master, then hear the difference before you export.

What Mastering Does

Mastering is the final stage between a finished stereo mix and release. It shapes the overall tonal balance, controls dynamics, manages peaks, and prepares the track to translate across different listening systems. It improves the complete mix; it does not replace detailed work on individual vocal or instrument tracks.

Prepare the Best Source

Export the highest-quality version of your finished mix and leave enough headroom to avoid clipping. MixMasterAI accepts audio uploads up to 200 MB. If the source already contains distortion or heavy limiting, those problems may remain audible after mastering.

Choose the Sound and Destination

The canonical mastering flow offers 8 genre choices, 8 release destinations, and 3 loudness profiles. These controls give the processing chain useful context without forcing you to understand EQ, compression, or limiting.
