VOC19

NAME

voc19 - JSRU style 19-channel vocoder

SYNOPSIS

voc19 (-i item) (-f) file

DESCRIPTION

voc19 is a straightforward implementation of a 19-channel filterbank analyser using two second-order section Butterworth bandpass filters spaced as in Holmes paper published in IEE proceedings. Energy smoothing done at 50Hz to give default 100Hz framerate.

There is no limit to the length of the input signal.

Options and their meanings are:

-I Identify program and version number.

-i item Select input item.

-f Faster frame rate. Sample output at 200 frames/sec, filtering remains at 50Hz to avoid pitch pulses.

INPUT ITEMS

SP Any speech signal sampled at greater than 8kHz.

OUTPUT ITEMS

CO Vocoder energies.
