FMTRACK

NAME

fmtrack - track formant peaks and generate synthesizer control data

SYNOPSIS

fmtrack (-i item) (-v) file

DESCRIPTION

fmtrack converts a set of spectral peaks to synthesizer control data in which the frequency, amplitude and bandwidth of the first four formants are specified every 10ms. Formant tracking proceeds in three passes: Pass 1 does primary reassignment of peaks, Pass 2 picks up basic tracks, Pass 3 "creeps" along existing tracks adding to ends. If a Fx contour is available in the file, it is used to create the Fx parameter in the SY item, otherwise a monotone of 100Hz is inserted.

Options and their meanings are:

-I Identify program and exit.

-i item Select input item.

-v Take voicing decision from FX data. Default: use "flag" value in FM data.

INPUT ITEMS

12.xx Any raw formant estimates item.

4.xx Any Fundamental frequency contour.

OUTPUT ITEMS

7 Formant tracked synthesizer control data.
