Hi Tejas,
You might try modifying os.triangleN(N,freq) to add a duty factor, where N
is the order of the aliasing suppression.
It's based on the paper "Alias-Suppressed Oscillators based on
Differentiated Polynomial Waveforms" by Valimaki et al.
My guess:
triangleND(N,freq,duty) = squareND(N,freq,duty) : fi.pole(p) : *(gain) with
{
gain = 4.0*freq/ma.SR; // for aproximate unit peak amplitude
p = 0.999;
};
squareND(N,freq,duty) = pulsetrainN(N,freq,duty);
Then your 25% case would be os.triangleND(N,freq,0.25);
Cheers,
- Julius

AI has taken my job, but only I know what it is.
