The dynamic range is so compressed that when viewing the raw samples, most of the track is saturated at almost 100% amplitude level. Blige's "Sweet Thing" is a typical pop mix which has undergone a lot of postprocessing in the studio. The track contains a very large dynamic range, which helps to test for DNR compression by the MP3 process. I chose this track because it is an excellent DDD recording of virtuoso piano playing with an orchestra. Evgeney Kissin's rendition of Rachmaninov's Concerto #3.As a baseline, I chose 192Kbps as the lowest MP3 bitrate, since this seems to be a commonly agreed upon threshold for "near CD quality," and most of the MP3's I've listened to encoded below 192Kbps have sounded too degraded for my tastes. ![]() Not being able to find much in the way of critical test results, I set out to perform some tests of my own. There has been much debate on the sound quality of MP3's vs the 16-bit linear PCM used in producing audio CD's.
