Re: Listening Tests

The goal in audio watermarking is that the listener should not distinguish
any difference between the original audio from the watermarked one. Now to
test this, I mean, should a same-different test do? Are there other tests
more suitable and generously documented and has its free gui implementation?
I don't have ITU access. Thanks.
