Find kick and bass frequency conflicts

The low-end lab compares two stems locally and reveals spectral overlap, simultaneous low-frequency activity and the strongest shared energy range.

Diagnostic starting point, not automatic EQ

PRACTICAL EXAMPLE · ILLUSTRATIVE, NOT A TEST RESULT

Try this: Export both stems from the same start point. Listen to the highlighted region in the full mix and try shorter bass notes or sidechain in your DAW.
How to interpret it: A high overlap score is a reason to listen, not an automatic EQ instruction. Intentional shared energy can stay.

Is all overlap bad?

No. Shared energy can be musically intentional. The index only identifies areas worth checking.

Should I cut the highlighted frequency?

Check arrangement, envelopes and sidechain first. A static EQ cut is only one possible solution.

Are stems uploaded?

No. Decoding and FFT analysis happen entirely in your browser.
