A high-frequency electronic discord tone (sweeping around high frequencies) suitable for ringtones and annoying dogs. Also suitable as a sound effect for 'sweeping the dial' on shortwave radio.
This is a sound made in audacity with a high frequency square wave slowed down. I have a question about this effect that sounds like a robot saying ''uaiuai'' ¿which is the name of this effect?if someone knows the name, please comment.
Heavy impact effect with resonating mid and high frequencies. This sample employs the full range of frequencies and uses multi-band stereo imaging effects.
Free! really high annoying white noise. Use it for tv and/or high disturbed signal or whatever. Ripped, recorded, worked and mixed with audacity. (mp3 - 11:39 mins).
Dl0ksc in cw qso of mar 10th, 2012, at 11. 50 utc on 10116 khz. Stable high frequency but multiple tone - spectrum. Audio frequency changes are due to my tuning of trx to hear multiple tone.
Radio frequency interference at the 1200 khz mark of the a. M. Band, caused by varying proximity to a laptop computer. Very active and obnoxious high-pitched static and squeals.
