Hi list,
does anyone know how to implement IEC 1260 compliant 3rd octave band
pass filters in pd, notably at mid frequencies below 250Hz (assuming a
sampling frequency of 44100Hz)?
I understand that the standard way of doing this is to downsample the
signal and to use filters with a corresponding higher mid frequency,
for which one can find biquad realizations.
Any ideas?
