[CLAM] ASSERTION FAILED ERROR

[RAVI GUPTA]

Hi,

I had written a code for computing the MFCCs from an audio file. Currently in the code below I am using the default configuration of every processing element so I am not configuring them.

#include <CLAM/MonoAudioFileReader.hxx>
#include <CLAM/SpectralAnalysis.hxx>
#include <CLAM/MelFilterBank.hxx>
#include <CLAM/CepstralTransform.hxx>
#include <CLAM/Audio.hxx>

#include<CLAM/XMLStorage.hxx>

int main(int argc, char ** argv)
{
    if (argc!=2) return error ("needs a filename.");

    CLAM::MonoAudioFileReaderConfig mReaderCfg;
    mReaderCfg.SetSourceFile(argv[1]);

    CLAM::MonoAudioFileReader mReader (mReaderCfg);
    
    CLAM::SpectralAnalysis spectralAnalysis;
    //specAnalysis.start();
    CLAM::MelFilterBank melFilterBank;

    CLAM::CepstralTransform cepstralTransform;

    CLAM::Audio audio;
    //mReader.start();
    mReader.Do(audio);
    //mReader.stop();
    CLAM::XMLStorage::Dump(audio,"Audio","audio.xml");

    CLAM::Spectrum spectrum;
    //spectralAnalysis.start();
    spectralAnalysis.Do(audio, spectrum);
    //spectralAnalysis.stop();
    CLAM::XMLStorage::Dump(spectrum, "Spectrum","spectrum.xml");

    /*CLAM::MelSpectrum melSpectrum;
    //melFilterBank.start();
    melFilterBank.Do(spectrum, melSpectrum);
    //melFilterBank.stop();
    CLAM::XMLStorage::Dump(melSpectrum, "MelSpectrum","melSpectrum.xml");

    CLAM::MelCepstrum melCepstrum;
    //cepstralTransform.start();
    cepstralTransform.Do(melSpectrum, melCepstrum);
    //cepstralTransform.stop();
    CLAM::XMLStorage::Dump(melCepstrum,"MFCC","MFCC.xml");*/
}

When I run this program I got errors:

Can anybody tell me what is the problem? I think the problem is in MonoAudioFileReader
but I don't know how to sovle it.

Thanks in advanced.
