wave_viewer

Wave Viewer is a Matlab-based analysis tool for speech waveforms.

viewer_end_state = wave_viewer(y, [options])

Wave Viewer takes a signal y and the following optional arguments:

  • fs sampling rate (default: 11025)
  • ms_framespec_gram (default: broadband)
  • ms_framespec_form (default: narrowband)
  • nfft number of FFT points/bins (default: 4096)
  • nlpc number of LPC coefficients (default: 15)
  • nformants number of formants to track (default: 3)
  • preemph pre-emphasis factor (default: 0.95)
  • pitchlimits low and high frequency cutoffs for pitch tracking (default: [50 300])
  • ampl_thresh4voicing voicing threshold (default: 0 (don't apply a voicing threshold))

or a single argument sigproc_params, a parameter struct from the viewer_end_state returned by the function.

Wave Viewer requires a few functions from Matlab's Signal Processing Toolbox (zp2ss and abcdchk).
