I thought people might be interested in some results I'm putting together of tests for MPEG audio decoder accuracy.

These are the same tests I wrote about some time ago, but now I have results for a much wider range of decoders, and across all three layers. MAD is still showing well, and is in fact the only decoder I am aware that will produce 24-bit output.

The results are interesting:

Worth noting is that MAD is the only decoder in the class of integer decoders that can produce fully compliant output.

Does anyone have any suggestions for decoders to test that are not listed?

I would like to test the ARM decoder somehow, but I don't know if I can get access to it.
