STFT configuration
Hi,
I'm using CLAM to develop an automated music transcription system for my MSc project. I'm using the SpectralAnalysis and the SpectralPeakDetection classes to produce an array of frequency peaks and their relative strengths. At the moment the output of my system looks something like this for a 3000 sample chunk of piano at C5 (44100Hz Sample rate):
Number of peaks = 56
1. Mag = 1 Freq = 527.066 Note = C5
2. Mag = 0.433355 Freq = 1106.62 Note = C#6
3. Mag = 0.234237 Freq = 2495.64 Note = D#7
4. Mag = 0.0988229 Freq = 2956.98 Note = F#7
5. Mag = 0.127852 Freq = 3501.44 Note = A6
6. Mag = 0.121919 Freq = 3885.22 Note = B7
7. Mag = 0.149638 Freq = 4367.42 Note = C#8
8. Mag = 0.157781 Freq = 5109.65 Note = D#8
9. Mag = 0.0964647 Freq = 5422.36 Note = E8
This is almost correct, having checked it against spectra produced by various audio applications but I have only managed to acheive this after spending ages configuring the window size manually:
//STFT method, performs the STFT on a
//chunk of Audio and puts the data into a
//CLAM::Spectrum object
void AMTPeakDetect::STFT()
{
SpectralAnalysisConfig config;
cout << "Enter Size:";
int size;
cin >> size;
audioData.SetSize(size);
int windowSize = 679;
int spectrumSize = 513;
config.SetSamplingRate(audioData.GetSampleRate());
config.SetWindowSize(windowSize);
spectrum.SetSize(spectrumSize);
spectrum.SetScale(EScale::eLog);
SpectralAnalysis(sa);
sa.Configure(config);
sa.Start();
sa.Do(audioData, spectrum);
sa.Stop();
}
Is there a way of setting the window size automatically to a value which produces a correct result? If not how would one calculate the optimum window size to choose. I've also tried using various different window types. Any help on this matter will be greatly appreciated.
Thanks

Just check the contents of /usr/local/Trolltech/Qt-4.4.0/lib so that it
contains the requested library QtCore.
The error suggest me that the Qt binaries you are using might need compilation
as 'frameworks' not as libs which was something we supported by the qt4.py
tool but we might have removed support as we moved to qt4 macports or
something similar. I dont really remember as i told you I am not the mac guy
here. Pau or any other mac user over there should tell you. The wiki for me
is not clear but i don't fully understand the terms in there.
