I’m trying to build an Eurorack phaser effect module, using DaisySP’s Phaser. The problem I’m facing is that at low LFO speed or if I slowly modulate the phaser frequency using a knob, I hear audible steps in the modulation of the phaser frequency. I thought I could get away by changing the Phaser to use doubles instead of floats in the frequency modulation part, but without success. Any tips?
I would be happy to look at this closer with you!
How low of an LFO speed would you need? I just tried
in the phaser example (DaisyExamples → seed → DSP → phaser) and didn’t hear steps. I also tried 0.5 as well (though I don’t hear steps necessarily, this low of a frequency just leads to a detuned effect and not really phaser-like). I hope this is the LFO frequency you were talking about.
This forum allows you to share audio files, so feel free to post a clip of what you are hearing.
As for the knob, could you share the modification that you made to the code? Thanks!
