Implementations of a few features for analyzing sound data.
For sound analysis I impolemented a few common sound features in MATLAB: Center frequency (centerFreq.m), Crest Factor (crestFactor.m), Formants (formants.m), Harmonics (harmonics.m), Peak frequency (peak.m), Ratio between two frequency bands (powerratio.m).
