Audio classification based on polynomial interpolation

الملخص EN

A new algorithm to classify gender based on autocorrelation is used, firstly the signal is interpolated (resample signal) to fill-in the gaps between the signal, and the signal is convolved to be Cross-Correlated (long signal for a shorter), so the gender is classified depending on pitch Cross-Correlation.

Finally, the gender is classified to be male if the pitch value range between 85 Hz and 155 Hz, and the gender is female if the pitch value range between 165 Hz and 255 Hz.

Key words: - digital audio, Pitch, Autocorrelation, Cross- Correlation and polynomial interpolation.
