[chuck-users] UAna autoCorr, xCorr and ZeroX

[fernando alonso]

Hi users,

I am writting a program to extract audio features but the autoCorr, xCorr
always give me a 0 value. ZeroX always give me 0.5 value.

This is a brief of the source code:

//Definitions for features extraction

adc => FFT fft =^ RMS rms => blackhole;

fft =^ RollOff rolloff => blackhole;

fft =^ Centroid centroid => blackhole;

fft =^ Flux flux => blackhole;

fft =^ ZeroX zerox => blackhole;

adc => AutoCorr autoCorr => blackhole;

fft =^ XCorr  xCorr => blackhole;


    //Feauture extraction

    fft.upchuck() @=> UAnaBlob blobFFT;

    rms.upchuck() @=> UAnaBlob blobRMS;

    (blobRMS.fval(0) * 100000) => volumenInst;

    rolloff.upchuck() @=> UAnaBlob blobRollOff;

    (blobRollOff.fval(0)*srate )/2 => rollOffInst ;

    centroid.upchuck() @=> UAnaBlob blobCentroid;

    (blobCentroid.fval(0)*srate)/2=> centroideInst;

    flux.upchuck() @=> UAnaBlob blobFlux;

    blobFlux.fval(0) => similitudInst;

    zerox.upchuck() @=> UAnaBlob blobZeroX;

    blobZeroX.fval(0) => zeroXInst;    ///<-----------

    xCorr.upchuck() @=> UAnaBlob blobxCorr;

    blobxCorr.fval(0) => correlacionCruzadaInst;  ///<-----------

    autoCorr.upchuck() @=> UAnaBlob blobAutocorrelacion;

    blobAutocorrelacion.fval(0) => autocorrelacionInst; ///<-----------


Kindy Regards.
