Hi Thor, > Unfortunately, early CD's sounded harsh (poor converters and > brickwall filters) As well as poor playback equipment. Until the introduction of oversampling filters on CD players, they used third order filters, which have aliasing issues. With an oversampling filter, a first order filter can be used, which removes the aliasing issue. > ...and later ones largely fell prey to > hypercompression. Huh? CDs are not compressed.
