Subject: [Nature Recordists] 16 KHz noise?
I've got a number of recent recordings with a significant signal at
16KHz (or 15,792 Hz perhaps)?
Is there some well known source for noise of this frequency? Or
electrical effect (power transmission lines interacting with MD
recorders?) known to cause it?
The noise appears in MD recordings from 2 different recorders, with 2
different microphones, with both soundcard digitization of analog
playback from the MDs and with digital transfer of PCM data. And I see
it in spectrograms computed with several different programs.
Any hints would be appreciated!
