No, thats not the case. If you bring up the bit rate to minimum 160kb and
have a good encoder (some cut off at 20khz) and have a good decoder, then it
is hard to notice the difference.
However, if you rate at 120kb/s compression and processing becomes invasive,
causing dropouts and breathing.
There are a few encoders which sound good, but after having a few 'social
enhancements' the quality deteriorates (perceived sound I mean). Typically
the MusicMatch real-time encoder is a 20khz cutoff job. Yea, I know, we cant
hear higher than about 15khz, but it is the transient information which is
valuable, and that is in the 15khz and above areas.
Re decoders if you are using Winamp then you are using a really bad decoder.
Our new freeware player uses the Xing decoder which is pretty clean. I am
not saying its the best, but certainly a big improvement on Winamp.
There is a great future for these forms of audio compression. Using 160kb/s
MP3 is getting pruddy dammed close. But the new formats of VQF and MP4 and
even MS (WMS) are capable of audiophile response given a good
encoder/decoder combination.
