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.
