- anfractuosity 9y agoHeh, yeah it's a bit excessive. I took the audio recordings first, then processed the .wav files later via FFT. That's a good point though, but having the raw audio does let me play around with different techniques at a later date. I will have to look into a sliding window, if that's what you mean though, because at the moment I'm simply looking at each chunk of N seconds of audio. When I've tweaked the approach it would definitely be better to switch to the type of system you mention.
