Hi
I am creating a GUI for a DSP filter effect (non PD) and I want to have logarithmic representation of frequency. Right now the scale is liniar - so half of the fader ranges from 10kHz to 20kHz. The total range of the fader is 20 to 20kHz.
Does anybody have a magic formula on how to make the fader act more "musically" (ie. the octaves have the same amount of space on the fader?
TIA
