A recording made underneath a very busy highway overpass.

Moving low frequencies sound fx.

This sound was the result of a scary accident. I was looking at the view in the webcam of an open doorway leading into a dark hallway in my house, when suddenly this haunting feedback faded in and looped repeatedly, until i pulled the volume down. It was unexpected, and quite unnerving. I had to laugh about it once i realized what had happened. But that first moment had me expecting some ghostly apparition to come in from the darkness. Anyhow, it's just an accidental feedback loop. I've had it in my archives for about 20 years now. I thought it might be useful to someone else. Enjoy!.

Ringmodulated inversion of my speech from the file https://freesound. Org/people/kb7clx/sounds/648443/ invertedspeechcq. Wav. I took the raw recording and used goldwave's mechanize effect to translate my voice to a center frequency of 14khz. I then demodulated it first at 10. 6 and then 10. 2khz meaning that what comes out is essentially the opposite sideband, offset by 3. 4 and 3. 8khz respectively. 3khz just didn't sound as good. The first i filtered with a low pass of 2. 9khz, the second was filtered to below 3. 4khz to emulate a communications receiver passband. I am speaking upside down as described in this video.

Being blind i can't see their diagram, but i've got my own by ear intuitive method, keeping in mind that oo and ee are farthest from each other, all other vowells get closer the closer they are to the middle of the human voice frequency range. I say: huhlay sue quee, sue quee, sue quee do ux. Cahlloong sue quee sue quee sue quee do ux. The ay in huhllay is like when a spanish speaker says béisbol (baseball). The a in cahlloong is like the a in cat if you're opening wide for the doctor. The oo is like the oo in book. Listen to the other file and you'll hear: hello cq cq cq dx. Calling cq cq cq dx.
