New pitch extractor based on Harmonic Product Spectrum algorithm. From a frame spectrum, estimates pitch by downsampling the spectrum
numHarmonicstimes. By multiplying the compressed spectrums, the fundamental frequency peak is enhanced and can be detected as the frequency with the highest peak on the resulting harmonic product spectrum. It filters in frequency depending on the parametersminFrequencyandmaxFrequency.Results of the tests
