Playing around with the excellent tuner at http://websdr. Ewi. Utwente. Nl:8901/. The website even has a recording button! this version is the same as "shortwave-sweep-and-beeps. Wav" except here i have limited it with a threshold of 10db, which decreases dynamic range but also makes it louder overall.

I recorded this today (1/12/23) from atlanta, where we had a bunch of heavy rain and tornado warnings this afternoon. The radio station i recorded this from is am 750. The first part of the recording isn't very interesting, but the part where she started talking about how you can't see any tornados coming was really interesting to me. I think this would make for some really good ambience in like an environmental horror track. I decided to include the whole recording anyways in case anyone wanted it. Here's the backstory to this thingey if anyone really wants it:we were on tornado watch as i was speeding trying to get home from work, when the sirens started to go off. I had to pull into a disheveled looking parking garage, as that was the closest place i could get to. The garage only had one level, so i had no way of getting to lower ground. I sat there in my car, terrified that i might be stuck there, in a shitty parking deck, in the middle of a giant ass storm, with very little cell signal, for hours on end. I decided to turn on my radio and record it from my phone. Fortunately, i was only in there for 30 minutes, and i managed to get home after the rain cleared up a bit.

Although the project inspire (nasa) seems to have died, there are still sources of sound sources of vlf noise in the net. In http://abelian. Org/vlf can be found several available streams from multiple receivers located around the globe. In this package, i simply offer a few records scattered in time from this site. The stereo samples correspond to a experimental stream that combines two sources balanced on each channel: cumiana vlf receiver (italy) + sheffield vlf receiver (uk). The mono tracks correspond to other indeterminate receivers.

Was up late last night and needed to make a foley for a radio tuning for a movie project thats coming up. So i thought i try and make my own. I just took my alarm clock radio and played with the am tuner and got some pleasing results. In the beginning it tunes in into various stations while coming towards the end its very errie with static and a wobbly tone. Feel free to use this for your own project. Use any part of this recording that pleases you and have fun! and feel free to share what you made with it!.

Recording of an empty radio frequency.

Created this sample using only audacity. I started off by generating a square wave chirp between 10000 and 20000 hz on a mono track, copied this created a stereo track and messed around with timestretching and low pass filtering until i got the desired sound.
