Create

Create brings up a new panel that is used to create the LPC and pitch analysis data files.  An unlimited amout of these panels can be created by choosing Create from the menu.

The panel is divided into three sections.

LPC

This top section contains the settings for the creation of a LPC data file.  The Frames and Poles are given the default values as specified in the Preferences panel.  The word all in the Duration field specifies that the entire field is to be processed.  A sound file must be selected first, either by typing in the name or selecting it from the open panel brought up by pressing the Soundfile button.  If no LPC filename is specified, the resultant LPC file has the same base name as the sound file, with a .lpc extension.  

PTRACK

The Framesize, High and Low cps fields are initially determined by the settings in the Preferences file.  The Interframe Offset is given by the number of frames specified in the LPC section. The Inskip and Duration fields have the same meaning as in the LPC section.  In order to better determine the correct values for the cps fields, you can type a tone value in the HZ (hertz) field and by pressing the HZ button, you will hear a single tone at that frequency.  The program that is called when the HZ button is pressed is determined in the Preferences panel.

GO!

Here is were everthing happens.  The Play Soundfile button lets you check your input file sound.  The Watch button opens up scroll view that allows you to see the error messages and output from the programs being called.  It is not fully supported and poorly implemented.  The View buttons open up the newly created lpc and pch files in their own new windows.  

The Go button runs all four programs needed to create finished lpc and pch files.  The LPC button only runs the lpc program and the stablilize program.  The Ptrack button only runs ptrack, and the Merge button merges the lpc and pch files.
