Why would xine reproduce telephone conversations?

If you run xine on a very low bandwidth modem stream, the sound will be slightly distorted in a way cable modem streams are not, and the background distortion sounds like telephone conversations, even with a cable modem transmitting at low bandwidth.

One theory: Xine developers use dirty virtual memory, which works fine at buffering high-speed audio. I mean, Xine and mplayer are that close from being nearly perfect.

I'm not completely sure I understand what you're asking.
Fundamentally, low-bandwidth streams will not sound as good as high-
bandwidth streams, otherwise nobody would ever use high-bandwidth
streams. Different encoding schemes have different issues, but
generally the sounds get a 'muted' or muffled effect and high-
frequency components are lost.

It's not any defect or quirk in xine. It's the nature of low-bandwidth
audio encoding -- some of the information in the original stream is
lost because there is not sufficient bandwidth to encode it all.
