    I've installed teensy on arduino ide this year, but i don't know why the audio library was old (2018), so I didn't know waveform_bandlimit_xxx :D Thanks

    it needs to be optimized but this is much better (synt_waveform.cpp) case WAVEFORM_TEST: magnitude15 = signed_saturate_rshift(magnitude, 16, 1); for (i=0; i < AUDIO_BLOCK_SAMPLES; i++) { index = ph >>...

    Hello. I tried to reset the filter with a new setting of the lower stage of the biquad (0) but the upper stage (1) remains set. So in the following code the final noise is different from the initial noise (at 400Hz)...

    Thank you Mark. So if i do biquad.setBandpass(0,1000,1); biquad.setBandpass(1,2000,1); biquad.setBandpass(1,3000,1); it's equivalent to : biquad.setBandpass(0,1000,1); biquad.setBandpass(1,3000,1);
