I have used VB FFT deconvolution code from S W Smith's marvellous "Digital Signal Processing" book to process 1024 sample chunks of geophysical data and would like to transfer this function to the Teensy 3.1. Each sample chunk is obtained at intervals of between 0.25 and 5 seconds. The processing extracts timed events, such as acoustic echoes, that are saved for further analysis. I would be grateful to hear if anyone has modified the audio FFT example provided with Teensyduino by changing the windowed operation for a discrete one. I imagine it would be straightforward but am not sure at what coding level I should modify the program, whether in the analyse_fft1024.cpp file, or elsewhere.
