268 Royalty-Free Audio Tracks for "Frequency Stretch"

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!.

This sound was created as follows:. -zynaddsubfx free (and insanely amazing) software synthesizer generated simple g tone using a sine-wave adsynth engine- creative sbs 250 speakers played it back distorting the sound naturally and adding some interesting stereo phasing effects (is that caused by analog signal cable being longer for one speaker?)- i was manually changing the volume using the speaker's potentiometer (whitch is dirty and added some interesting noises on the right speaker, and also at peak loudness during the 54th second the right speaker is quiet)- the output was captured by zoom h2's rear mics- and recorded via usb into audacity free audio editing program- i exported the recording as 16-bit flac.

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.
