Audio resolution is the ability to retain as much of the original performance as possible with current equipment. - Teresa 17:08:27 06/20/06 (46)

Based on your definition, your anwers are so wrong that I am stunned! - Richard BassNut Greene 09:55:34 06/22/06 (8)

Perhaps not, but one instance of Redbook CD playback that sounds good - Al Sekela 10:41:42 06/21/06 (2)

So any PCM at 24 Bit 48kHz or lower including CD is more to susceptible RF noise than higher resolution PCM? - Teresa 11:03:30 06/21/06 (1)
