A stride log2n FFT_FORWARD vDSP_fft_zrip setupReal A stride log2n FFT_INVERSE FFT on n real floats and then reverse to get back to where we started. ip stands for in place which means A gets overwritten.. and we have set it up so that some callback gets triggered every time the microphone gets in 1024 floats. Supposing the microphone sampling rate was 44.1kHz so that's ~44 frames sec. So our time window is.. window is whatever the time duration of 1024 samples is ie 1 44 s. So we would pack A with 1024 floats from the mic set log2n 10 2^10 1024 precalculate some bobbins setupReal and vDSP_fft_zrip setupReal..

easier. Basically at the heart of it is vDSP_fft_zrip setupReal A stride log2n FFT_FORWARD vDSP_fft_zrip setupReal A stride log2n FFT_INVERSE FFT on n real floats and then reverse to get back to where we started. ip stands for in place which means A gets overwritten That's the reason for all this special packing malarkey.. say we want to perform pitch detection on microphone input and we have set it up so that some callback gets triggered every time the microphone gets in 1024 floats. Supposing the microphone sampling rate was 44.1kHz so that's ~44 frames sec. So our time window is whatever the time duration of 1024 samples is ie 1 44 s. So.. rate was 44.1kHz so that's ~44 frames sec. So our time window is whatever the time duration of 1024 samples is ie 1 44 s.
