I have read that "Debauchies Wavelet is simply a short FIR" so i am searching for a single FIR that i can make into a filterbank, a precise "bandpass filter" that detects narrow frequencies, i.e. 1Hz resolution and very narrow.
Having an FIR filter function allows for multithreading which is not easy with a transformation matrix, and arbitrary analysis windows.
In Reaktor DSP suite i simply used a bandpass to make an amazing filterbank program. I tried the same with a cookbook FIR filter and it was totally erratic and garbled as a filterbank analysis filter, even though it sounds good.
What FIR or wavelet can i use for a filterbank where:
T=time, F=freq; for loop T++; // (1 second 0-44100 samples) for loop F++; // (512 bands 0-512 kHz frequencies) graph2D[T,F] = FIRfilter(T , F );
