What is the correspondence between a float (number between 0 and 1) and a frequency ?
For example for a high pass filter :
- cut at 150 Hz = float(x.xx)
- and vice versa float(0.35) = x Hz ?

Not sure I think it's dial² interpolated over 20Hz to 20kHz, it might even be dial³

There's no fixed rule here, so depends a bit on what you're making which part of the frequency range is more important to you.
For the default filter the range is indeed cubed, but for the echo it's linear for the high pass and squared for the low pass.

how about the native separate filters, [something I thought about be never checked]

Also cubed, but over the range of the entire knob instead of only half.

I'm using a cubic mapping as well.

mmmmhhh .. I don't really know how to use or enter equalizer frequencies in an effect ..
But in the program itself I have set it that way.
There it is entered in Hz

@djdutschi, entirely different thing.

That may be true. But there are also a couple of effects that access the equalizer frequencies ;-)
That's why I wrote this.

I realized that my question is silly because I was taking the problem backwards.
Just determine a frequency in hertz (example 500 Hz) and use it as it is in a formula like w = 2 * PI * 500 / SampleRate
