• Takes PCM Wave input and outputs MFCCs as comma separated floating point values, each line representing a frame.
• Supports batch extraction through list input and output.
• Command line control for window length, frame shift, sampling rate, number of cepstra and filterbank cutoff frequencies.
• Computes MFCCs through pre-emphasis, Hamming window, FFT, power spectrum, equal height log-Mel filterbank followed by discrete cosine transform.
