AAC listening test - Encai Liu - Jan 21 3:26:00 2002



Hi, All

I am working on advance audio coding project.
I was asked to implement the decoder using a Fixed-point DSP.
My question is how I test my Fixed-point AAC decoder and is 
there any standard for testing it.

thanks for your help

regards

encai

Hi,

there are performance bitstreams and a tool that checks if the
decoder output is valid.
Links to some reference bitstreams can be found (for
example(?)) here:

Of course not "performance" but "conformance testing"
bitstreams :)
