I recorded mostly nothing, then normalized it, so it was mostly loud static. I used audacity's noise remover to make the sound and it's wahwah effect to make it move across stereo space. Very interesting, good for static and alien voices.
In honor of my new guru pramahansa yogananda, i searched for a swan sample. Then i added: time stretch, high pass sweep, flange, rotator pann, delay @ 124 bpm,. Thank you guru, namaste.
This is audio i recorded of my husband using his ten year old decrepit constant positive air pressure sleeping machine. I was trying to convince him that he needed a new one. The variety of sounds he and it managed to make is extraordinary. The intermittent beeping is the machine's warning sound. When i played it for him he cried laughing. I hope you find it useful for something. You'll be please to know his new machine is whisper quiet.
I auto tuned a sound i previously recorded on my crappy phone. The original sound was created on fl studio. I used the autotune app called voloco on my phone and autotuned it.
For the sound i would like to create like an "extraterrestrial signal", i took a "sifflet" and i play with it, add opening and closing effect, reverse the sens and finish the set with a battery sound to put a bit of "suspens". . .
