Beats Per Minute detection and FFT

[Eric_Lin]

Hi,
Recently,I’ve been trying to implement some applications about audio. What I want to do is to read the stream buffer(the audio maybe comes from website or phone’s SD card), and give it to FFT to analysis its frequency maybe show the correspond frequency on the screen. Is there any one might know where I can start? Sorry for my bad English btw. Thanks in advance.

there are 1-2 bpm assets on the asset store, it would save you a while coding. the FFT function is integrated in Unity, check the references and forums. BPM involves counting peaks and finding what times they happen at, it’s general programming research, i.e. google all the info you can. I think that you can read the buffer from OnAudioFilterRead into another array and work on it from there. or directly on the sound files.
