C++ (Cpp) absoluteThreshold Examples

Example #1

File: YIN.cpp Project: DannyvanSwieten/APAudioFramework

float YIN::analyze(float *input)
{
    squaredDifference(input);
    normalizedDifference();
    int tau = absoluteThreshold();
    if(tau != -1)
        return 44100.0 / tau;
    else
        return tau;
}

Example #2

File: Yin.cpp Project: itsmyth/Yin_test

float Yin::getPitch(float* buffer){
int tauEstimate = -1;
float pitchInHertz = -1;

//step 2
difference(buffer);

// step 3
cumulativeMeanNormalizedDifference();

//step 4
tauEstimate = absoluteThreshold();

//step 5
if(tauEstimate != -1){

pitchInHertz = sampleRate / parabolicInterpolation(tauEstimate);
}

return pitchInHertz;
}
