In Reply to: Ultrasonic Nonsense, speakers, etc. What do you guys think? posted by g_greenamyer@yahoo.com on March 11, 2012 at 20:48:58:
There are recordings that have musical energy well above 30 kHz. I have a few dozen such digital downloads, mostly 192/24, such as the Acousence recordings that can be downloaded from Linn Records. Even older analog sourced recordings (at 192/24 or 96/24) have high frequencies up to about 30 kHz, as limited mostly by tape. Many of these can be downloaded from HDtracks. The spectrum plot feature in iZotope RX makes this obvious. There are commercial microphones being used to record classical music that advertise response to 100 kHz.
There are speakers that go up to 40 kHz. (I have such a pair.)
Whether response from 20 to 40 kHz affects sound quality is a separate issue. It's certainly inaudible on sine waves. (Fifty years ago I could hear 21 kHz, but now it's only 14 kHz at moderately loud volume levels.)
