Just a minor nit-pick: AM radio can be stereo. However its use is almost nonexistent.

Telephone lines (POTS) have a frequency range of 300-3400Hz. That means 7kHz mono should be enough, although 8kHz is generous towards the transition bandwidth/roll-off. - Andrew _______________________________________________ Flac mailing list [email protected] http://lists.xiph.org/mailman/listinfo/flac
