mel frequency cepstral coefficients labview

Bridle and Brown used a set of 19 weighted spectrum-shape coefficients given by the cosine transform of the outputs of a set of nonuniformly spaced bandpass filters. An MFCC can be approximately inverted to audio in four steps: a1 inverse DCT to obtain a mel log-power [dB] spectrogram, a2 mapping to power to obtain a mel power spectrogram, b1 rescaling to obtain short-time Fourier transform magnitudes, and finally b2 phase reconstruction and audio synthesis using Griffin-Lim.
