Here are a couple of test files developed by Robin Miller to aid in the development of ambiophonic processors.

One is a recording of Robin speaking and panned left, right, and center. This is a good test of the processors with and coloration.

The other file is a dirac pulse at 44100 Hz. Play this though your processor and record the output. Robin has agreed to analyze these output files on his system.

The ultimate verification is, of course, the sonic results.

I guess the Dirac test/verify is for the RACE version, and not yours?

Well, it is for virtually anything. Record the impulse response and you have a way of analyzing the processor.

You mean Robin Miller will analyze a Dirac processed by your version of the ambiophonic processor? (it wil have a totally different impulse response than the RACE one)

Edit: if not perhaps you can generate a test file, using your VST, from that Dirac pulse?

There are differences between mine and the RACE processor, of course. He'll look a the response for things that look flakey. It's just a sanity check.

I'll record my VST's response and post it, for reference though.
