Therefore, the highest frequency which can be accurately reproduced from a 44.1 kHz digital recording is 22.05 kHz, which is within the range of hearing of several folks posting here. I suspect my audible range reaches up there, too, since I can hear department store burglar alarms and CRT flyback transformers. -- Bill Eason (803) 791-6348 ...bill.eason@ncrcae.Columbia.NCR.COM NCR Corporation E&M Columbia 3325 Platt Springs Road West Columbia, SC 29169
