Mix Analyzer

A free tool that checks your mix or master and reports loudness (LUFS), true peak, clipping, stereo image problems, dynamics, and tonal balance. Every finding comes with plain-language advice on how to fix it. The analysis runs locally in your browser, and wherever mastering would audibly improve your track you get a free 30-second preview to hear the difference.

Yes, completely free for everyone with no account needed. Since all processing happens locally in your browser, there are no usage limits. If the report finds problems, Bandmixr can master your track or mix your stems to fix them.

The analyzer detects automatically from loudness and peak measurements whether your file is an unmastered mix or a finished master, and judges accordingly. An unmastered mix is checked for healthy headroom and mix problems, since loudness comes later in mastering. A finished master is checked against streaming delivery standards like -14 LUFS loudness targets and the -1 dBTP true peak ceiling.

Yes. A finished master is checked against streaming delivery standards, and if the analyzer finds something a mastering pass can genuinely fix, such as a tonal imbalance or peaks over the ceiling, you hear it in a free 30-second enhanced preview. Already-mastered tracks are never pushed through a second full mastering: the engine runs a gentle polish pass that avoids double limiting. If your master checks out, the report says so, and there is nothing to buy.
