Retrieving entire timeline's sound file spectrum

FMOD Engine

Hi ,

I need to get FFT of a sound file to display a spectrogram for entire sound file timeline.
I was able to get the FFT after calling play on the sound file, however, as far as I understand it just gives me the first window, how do I go about and “move” that sliding on the entire file(without missing windows)? Is there a callback I should hook into where I could call “getParameterData”

Any help will be appreciated!

I think I might need to see how you are using the FFT to understand the question here- is this audio file being played back in real-time? The spectrum data is populated during System::update, so while playing back an audio file the FFT spectrum data will also be filled.
