Mix Readiness Checker
Know before you payfor a master.
Upload your mix, analyse it for free, and read the full readiness report — score, warnings and recommended preset. No card required.
What gets checked
Six of the things that trip up masters.
Every readiness check runs on the automated mastering flow. You’ll see the full list of warnings before you pay — not after.
Integrated LUFS
How loud your mix is overall. Too loud suggests heavy limiting already on the mixbus.
True peak
Inter-sample peaks. Anything above 0 dBTP means clipping that mastering can’t recover.
Loudness range
How dynamic your mix is. Too narrow and the record will feel flat on streaming.
Phase correlation
How mono-compatible your stereo field is. Negative correlation warns of cancellation.
Stereo width
Low-end too wide triggers mono-folding warnings. We’ll handle it either way.
Brightness & harshness
Spectral balance. Too bright or too dark gets called out, with a recommended preset.
What a good score looks like
- Integrated LUFS between -16 and -10
- True peak below -1.0 dBTP
- Loudness range above 6 LU
- Phase correlation above 0.5
What warnings to watch
- True peaks at or above 0 dBTP = clipping in the source
- Integrated LUFS above -9 = heavy limiting already applied
- Phase correlation below 0.2 = stereo cancellation
- Stereo width above 0.9 = low-end too wide
