Free mix analyzer: Catch mix problems while they are still easy to fix.

This free mix analyzer flags clipping, mono phase problems, low-end issues, DC offset and silence before mastering.

What you get

  • Find problems while the mix is still open. Clipping, phase and low-end issues flagged before you master.
  • See how it holds up in mono. Mono fold-down loss and stereo correlation, including in the low end.
  • Copy the findings. Send them to whoever mixed it, or keep them for the next bounce.
  • Keep unreleased music private. Measured in your browser; your audio is not uploaded or saved.

Your audio and its file name stay in this browser. Bounce Sessions does not upload or save them. Our analytics can count each check with rounded results, such as a loudness band and how many fixes it found. In the UK, the EEA and Switzerland, nothing is sent until you allow analytics. Elsewhere, that is sent without cookies unless you allow them. How we use your data. Copy findings if you want to keep or share them.

What it measures, and what it does not.

Every check is a measurement with a fixed limit, the same for every file. It does not judge tone, balance, arrangement or performance, and it never compares your mix with other songs. A reading is a reason to listen again, not a verdict: a clean, unclipped file matters more than hitting any one headroom figure.

Mastering takes WAV, AIFF, FLAC or MP3 at 44.1 to 96 kHz: Tracks can be up to 12 minutes. Unlimited or a track credit supports up to 30 minutes at 48 kHz or below (15 minutes at 96 kHz). The engine measures your mix again while it masters, and those readings are the ones on the master's page.
