About tkSound

This is a screenshot of the current state of the soundfile examiner I am developing under tk. The idea is to provide a range of tcl/tk extensions that will allow end-users to build a variety of sound viewers (and perhaps eventually editors) according to their own taste.

Currently, these are the components:

tclSound - a new tcl command, 'sound', to instance tcl objects corresponding to sound data (currently AIFF files on disk).
tkSndWvfm - a tk widget to display sound data as a waveform.
tkTimeline - a tk widget to display an automatically-scaled labeled axis.
tkImg - a tk widget that displays a 2D array of bytes (currently read from a disk file) as greyscale image.
tohex - C application to analyze soundfiles with the short time Fourier transform into a data file suitable for tkImg to read.
tsoundg - tcl script that uses the above extensions to allow soundfile examination as in the screenshot above.

This was started as a 'recreational' project for me while I was finishing my Ph.D., so it doesn't get a lot of attention. But I love the way tk/tcl encourages projects to be modularized to promote sharing and user configurability, so I'm keen to let other people have this stuff if it could be useful.

Currently compiles on Solaris (plus SGI and DEC OSF?). Should port to most Unix systems. Pre-release of what I've done so far is available here.
