How to determine the pitch from GetSpectrumData() to make a polyphonic tuner?
Hi,
I'm currently stucked with no clues on how to get accurate analysis of the getSpectrumData. I'm trying to make a pitch detection or polyphonic tuner for guitars. My existing idea is to pinpoint the exact position of every pitch on the guitar frets through the samples:float［］ data. Does anyone know an effective way to collect those data or any other workaround to make a pitch detector? Thanks in advance.
I've found some resource http://answers.unity3d.com/questions/127562/pitch-in-unity.html http://www.kaappine.fi/tutorials/fundamental-frequencies-and-detecting-notes/ http://answers.unity3d.com/questions/175173/audio-analysis-pass-filter.html http://answers.unity3d.com/questions/720179/getspectrumdata-cant-recognize-correct-note.html
$$anonymous$$ost of it is from Aldonaletto. However, I keep on getting frequencies that are higher than usual. For instance, C3 should be 130.8 or 131, but I got something that is close to C-middle, which is 262, but the result was 266.
I'm running on FFT with 1024 samples, blackmanharris, sample rate 44100 hz. I also tried running with 2048 samples, but it causes lower sensitivity. I also found out that there's not much difference running sample rate of 48000 hz. Can someone please help out here?
I'v been searching and trying for weeks and the results are same as yours not even close, please if u find something can u share it.
