What is the right way to feed chunks of my recorded swept sine and get back 512 frequency points which take into account all the data I passed in?
Why did you pick 2^16 anyway?
Quote from: saratoga on 17 April, 2011, 01:50:27 PMWhy did you pick 2^16 anyway?because the length (in samples) of the audio signal is somewhere between 2^15 and 2^16 so when I pad it with zeroes to the nearest 2^n number, I get 2^16. It was the first idea that came to my mind because then I could feed all at once and grab the response with all the data in one chunk Yes, you definitely are right - the best way would be to create FFT of more appropriate size. The problem is that I have no idea how would I combine the response if I split audio in chunks with 1024 size - what do I do with the results?
