Karlheinz has the 13dB miracle still. I lost it a long time ago, and got it back from him recently (rather annoying to be the one who made it and then not have it due to companies falling apart...) I don't read the fhg web site for rather a number of reasons, so Max, is it upon that site? jj __________________________ James D.

As a student I personally found the presentation of the "13db miracle" the most impressive and straightforward demonstration of psychoacoustics in audio coding. Of course that would require your students to have an understanding of the principle of SNR.
