Subtle noise made by a bose wireless speaker while on stand-by: static noise accompanied by repetitive blows and low electronic beeps. X/y stereo (zoom h5).
I've scanned the radio frequencies with an old radio and recorded with my tascam dr-05 via the headphone jack. You can hear some weird looping patterns and sound fragments from random radio stations.
Recording of the static noise of my babyphone. Recorded with zoom h1. Free to use, no credit needed. You can't let me know in the comments for what you have used it.
