Abstract
When testing low bit-rate, i.e. audio systems comprising perceptual coding, one has to use test stimulus similar to real-world signals; on the other hand, it is necessary to use some kind of estimation of the temporal behaviour of human hearing process. This article shows the results we have obtained using our own developed test stimulus called CATS (composed audio test signal), and further analysis that gives transparency reduction as a measure of quality.
