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.
