The following are exectutable programs which are used for signal processing:
is used to provide produce a variety of feature vectors given a waveform.
is used to produce spectrograms from utterances.
performs filtering operations on waveforms.
performs pitch detection on waveforms. While sig2fv can perform pitch detection also, pda offers more control over the operation.
produces a set of pitchmarks, specifying the instant of glottal close from laryngograph waveforms.
The following programs are also useful in signal processing:
performs basic operates on waveforms, such as adding headers, resampling, rescaling, multi to single channel conversion etc.
performs basic operates on coefficient tracks, such as adding headers, resampling, rescaling, multi to single channel conversion etc.
