The Adaptive Optimal Kernel(AOK)
for Desktop Computers
Last Updated September 22, 2006

Based on the work of Douglas L. Jones and Richard G. Baraniuk
For more information, please visit their site.

Platforms Supported:

Macintosh, Power Macintosh and Pentium based PCs.


Primary Uses:

Analysis of time-varying acoustic signals in high noise environments. Can be used to analyze large data sets(70000+ data points) using common Desktop Personal Computers. Results are easily imported into MATLABTM or similar analysis program.


Software Available:

The Macintosh PPC or Pentium versions are highly recommended due to the computational requirements
of the AOK TFR. Macintosh 68K versions are for those without a PowerMac and lots of time.



Source Code:


Typical Performance:

For a 64x64 calculation of "papertest.sig" included with the above software.

For The Experimentalist:

I tried to make an "All-In-One" TFR calculator based on the above code. If you're a programmer and want to see how the Wigner and Choi-Williams TFRs compare to the Adaptive TFR, please click here. The zip archive includes source code, a Mac version and a PC version. Follow the instructions provided with the AOK code above. More generic source code for other Windows compilers can be downloaded here.
