Adaptive Optimal-Kernel (AOK) TFR
Description
C language source code implementation of the algorithm derived in
- D. L. Jones and R. G. Baraniuk, An Adaptive Optimal-Kernel Time-Frequency Representation, IEEE Transactions on Signal Processing, vol. 43, no. 11, pp. 2361-2371, October 1995. Abstract.
Program outputs Matlab-compatible ASCII data file for ease of display. A C-Mex version for Matlab is planned for the year 2040.
Examples
- AOK TFR of a train of bottlenose dolphin clicks.
- Postscript plots comparing the AOK with traditional TFRs on a test signal (200k), bird call (60k), and speech signal + references (640k).
Installation
Download the most recent source code (Version 4.0, February 1996) of aok4.c or view the documentation and installation information. (The tar file archive contains both latter files.)
