I'm not yet well educated on the DSP subject, but I've initiated a project where I will do some audio filtering. My intuition tells me that there is a link between the coefficients of a FIR filter and the response of the audio indicated by values of a fourier transform.
My question; is there a way to go from FFT data to FIR coefficients? What about the other way around?
I apologize that I probably do not use the correct terms. Thank you for any response :)
EDIT: I got a request to make this clearer, so here is some pseudo code of what I want to do given a stream of audio data:
fftdata = fft(stream) soSomethingTo(fftdata) //for instance increase bass response FIRcoef = translate(fftdata) stream = fir(stream, FIRcoef)
So, this would analyze the stream and create a FIR that slightly modifies the fft response.
