MP3 has a certain amount in common with noise reduction algorithms, although what is is trying to reduce is weak sounds so close to the signal that they won't be heard. With very good noise reduction it may completely blank noise that was only reduced by the noise reduction. Whether it is valid to test noise reduction with a human ear, after the signal has been MP3 coded, depends on whether or not you believe that MP3 only removes what cannot be heard, anyway. One should never use MP3 on signals that are going to be processed by something other than a human ear, and I'd personally be wary of using for any comparison of audio quality. By WAV I'm assuming you actually mean 16 bit linear audio, as WAV is a wrapper format that can wrap MP3. Unfortunately, in the same way that JPEG seems to be used for all images on the web, MP3 tends to be used for all sounds. Both make assumptions about the nature of the signal and human perception. (PNG is often the best format for screen shots, for example.) -- David Woolley "we do not overly restrict the subject matter on the list, and we encourage postings on a wide range of amateur radio related topics" List Guidelines <http://www.elecraft.com/elecraft_list_guidelines.htm> ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
