My first assignment as a research assistant for Professor Douglas Jones
is to develop the Time-Frequency Representation Software package. It is
an ongoing effort. You can find about relevant information here.

Sometimes it is not enough to look at signals only from the temporal
domain or frequency domain, especially for non-stationary signals such
as the human speech. Thus, it is best to do a time-frequency analysis
and look at the signal at a time-frequency grid. This software package
calculates various TF representations of a given signal.

This software package is written in C++ and fully extendable. It includes
common TFRs such as STFT, WVD, Wavelets and various Kernels (Corn,
RGK, etc). It accepts ASCII or binary data file and Matlab MAT file as
input, and outputs ASCII or binary data file and MAT files. It is
written for functionality and thus NOT optimized in terms of
speed. It is a command line program with an optional Tcl/TK user
interface. It supports all platforms where an ANSI C++ compiler is
available (tested on Windows, Solaris and Linux).

This software package is not fully finished but near completion. Once
it is ready to be released, an alpha test version will be posted in
this website. It will be released in both source code and binary
executable format with full documentation. It will be released under
GPL 2.0 as OpenSource free software.
