How do I choose crossover frequencies for multiband processing?

Pick your source type and the number of bands you want. The tool suggests conservative crossover points based on standard frequency region boundaries for that material.

What is a good crossover point between low and mid bands?

It depends on the source. For a full mix the tool typically suggests splitting around 120 to 250 Hz. For something like a kick drum it separates sub weight from the beater click higher up, around 120 to 400 Hz.

Why are the crossover values called starting points?

Because the right split depends on your arrangement and source material. The tool gives you defensible boundaries based on common practice. You still need to listen and adjust for your specific track.

How the math works

There is no universal split that works for every source, so the tool sticks to standard frequency-region boundaries and only suggests source-specific values when a starting point is reasonably established.

When you would use it

Split a full mix into low, mid, and presence zones before multiband compression.
Separate kick drum weight from beater click for parallel processing.
Set a bass multiband split that isolates low-mid congestion from string definition.

FAQ

Why are these only starting points?

Because source material and arrangement change where the useful boundary should be.

Why not invent values for every possible combination?

Because made-up precision is worse than an honest starting range.

Should I still use a spectrum analyzer?

Yes. Ears first, analyzer second, presets last.
