Scripts

This section explains which volunteers contribute their free time to maintaining and updating the following scripts and a brief description of these scripts.

/!\ These scripts are available from a linux shell.

Linux usage scripts

Script

use

Maintainer

vnccheck

will provide the details of only a specific user's vnc sessions on a single machine

DanielWakeman

vncserver.glx

will select the best machine on the cluster for a graphics card tied vnc session and start that session (accepts all variables)

DanielWakeman

vncserver.rh4

will select the best rh4 machine on the cluster for a basic vnc session and start that session (accepts all variables)

DanielWakeman

vncviewer

application for vnc viewing

DanielWakeman

Audio scripts

Script

use

Maintainer

amplitude

Shell script that reports RMS amplitude and max-min intensity for .wav sound files.

DanielWakeman

amplitude.praat

Praat script used by "amplitude"

DanielWakeman

catwav

Concatenates .wav sound files

DanielWakeman

cuewav

Reports and/or manipulates cues in .wav sound files

DanielWakeman

duration

Reports duration of .wav sound files (using infowav)

DanielWakeman

extract_all_cues

Extracts marked sections of .wav files (I think... written by Dennis Norris, commented by Matt Davis)

DanielWakeman

infowav

Reports information on .wav files (Duration, Cues, etc)

DanielWakeman

praat

Software for "doing Phonetics by Computer" (http://www.praat.org/]). Used by amplitude and other useful scripts.

DanielWakeman

schroeder

Converts a sound file into white noise with the same amplitude envelope based on the method described by Schroeder (1968, JASA). NB: This is not the same as a one-band vocoder (which uses a smoothed amplitude envelope), or SCN (which maintains the spectral profile of speech). For more information ask Dennis Norris or Matt Davis.

DanielWakeman

showallvncs_really_really

will show the process information for all vnc sessions running on each machine of the cluster

DanielWakeman

showallvncs_really_really_cnt

will show the # of vnc sessions running on each machine of the cluster

DanielWakeman

splice

Combine or extract sections from .wav sound files.

DanielWakeman

xsplice
