LPC - a NeXT adaptation, with graphic user interface, of
Paul Lansky's software for linear predictive analysis and
pitch tracking

LPC (from shell or NeXT Workspace)

LPC performs linear predictive and pitch tracking analyses
respectively on a monaural shortsam or float soundfile. The
soundfile analyzed must have a valid NeXT soundfile header.
NeXT-CSound uses a modified IRCAM-type header whose first
element is a NeXT header. The two resulting data files may
then be merged in a manner suitable for use in a CSound
instrument via the lpread and lpreson units. The analysis
data may be displayed in a scrolling text window.
