Trying to duplicate what you suggested using Tukey and Kaiser, this seems to work but probably there are more precise ways to do this?...
Started experimenting with SciPy. Goal is to create linear phase brick wall Chord type filter. This seems to work but creates messy stuff on...
SciPy looks good, how do I get the FIR coefficients out of it? Can I avoid Octave and do everything in SciPy? I like either the min phase short...
I have the following code working: fs=705600 % Sample Rate (Hz) fc=21000 % Corner freq. (Hz) tbw=80 % Transition band width (Hz) attn=300 %...
Thanks for the info, I am starting down the rabbit hole with Octave. Trying to create an apodizing linear phase filter upsamping 16x Found some...
I tried your coefficients with sox for 44.1 to 176 - very impressive! I need to upsample to 705/768 at 32 bits from each of 44.1, 48, 96, 176,...
