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).
