I would have posted a direct link to it, if I had found it before. Searching for "13db miracle" on the web already results in a couple of hits, including a PDF of an AES 2006 presentation from Marina Bosi. The audio files are not included, though. I would think a similar experiment could be repeated without much effort. Regards, Max James Johnston wrote: > Karlheinz has the 13dB miracle still.
