What difference does that make? The upper limit of a person's hearing has nothing to do with whether the high frequency signal is associated with a lower frequency one. If anything, it'd be harder to detect the presence or absence of a very high frequency component along with a lower frequency fundamental because the latter would be much stronger. > ...However, musical instruments do not > produce pure sine wave tones, but rather complex waveforms with high amounts > of harmonics. Since the third harmonic of a 14 kHz cymbal or bell note is > 42 kHz, 22 kHz is nowhere near adequate for proper reproduction. Prove to me that you can HEAR 42 KHz and I'll believe you. Phil
