Dear List members, I have been looking for literature on state-of-the-art digital compressors for audio signals--something along the lines of Jon Dattorro's excellent "DSP Music Toolbox" papers in Journal of the AES 45(9&10). All I have been able to dig up was a crude description of the simplest possible compressor, where the signal is scaled by a low pass filtered version of the absolute value of the signal. Not very informative--that would be anybody's first guess..... However, I suspect that the best digital compressors of today employ much more clever processing. Does anybody know of written reports on this? Perhaps this is asking for well protected industry secrets, but I'll have a go anyway. Thank you in advance, Soeren. ================================================== Soeren Laugesen, Research Engineer, Ph.D Oticon Research Centre, Eriksholm Kongevejen 243 DK-3070 Snekkersten Denmark Phone: +45 49 22 00 01 tone 13 Fax: +45 49 22 36 29 email: slu(at) ================================================== Email to AUDITORY should now be sent to AUDITORY(at) LISTSERV commands should be sent to listserv(at) Information is available on the WEB at
