I'm surveying for feasibility techniques for a potential future project that's rather out of my past areas of expertise, and I have a fairly basic question. Of course if it looks feasible I will have to learn a whole lot more on the topic.
What is the equation to compute the number of FFTs/IFFTs per sample required, given the number of samples in the FFT n, the number of samples in the FIR m, and the number of samples of audio data this is applied to at a time x?
