This was made using a modular synth patch. It sounds like the interface of a retro spaceship from a science fiction film. Some noise is intentionally introduced.
Digital radio tuned to a cell station, cw modulation. Makes a spacey sound, good for ambient spaceship fx. Recorded with sdr# software and rtl dvb dongle tuner.
Brown noise generated in goldwave, then i applied the flanger effect to this sound about three times (or maybe two, i don't remember. ) it is useful for machines or whatever you like. Loopable.
This is a sound effect i created using bfxr. You don't need to credit me. You can download this file as needed and use it for anything. You can support me by donating to my ko-fi page here: https://ko-fi. Com/staycalm182.
