# Programs

The following are exectutable programs which are used for signal processing:

## sig2fv

is used to provide produce a variety of feature vectors given a waveform.

## spectgen

is used to produce spectrograms from utterances.

## sigfilter

performs filtering operations on waveforms.

## pda

performs pitch detection on waveforms. While sig2fv can perform pitch detection also, pda offers more control over the operation.

## pitchmark

produces a set of pitchmarks, specifying the instant of glottal close from laryngograph waveforms.

The following programs are also useful in signal processing:

## ch_wave

performs basic operates on waveforms, such as adding headers, resampling, rescaling, multi to single channel conversion etc.

## ch_track

performs basic operates on coefficient tracks, such as adding headers, resampling, rescaling, multi to single channel conversion etc.
