You may have thought that I have posted some random clips of audio on this site in the past. That is a fair statement, but tonight I have converted seventeen recordings I have made with my Sony Ericsson K800i mobile phone to .wav format. They are more nostalgic than useful so I won’t be posting all of them, but they do have a certain charm in an ultra lofi way.
The phone records sound at 16 bit. The sampling rate, on the other hand, is only 8 kHz – nowhere near the fidelity of standard audio CDs (44.1 kHz). So here is something on a pretty high magnitude of randomness: a drum jam I recorded at a little open air club in Playa del Carmen, Mexico back in March, 2007. The music was good. The tequila was better. The recording is awful. If you brave this one out, then you know what an 8 kHz phone recording sounds like.
Phone Recording of Drum Jam in Mexico
This sound was captured accidentally in my living room as I fiddled about getting ready to record my piano. The hardwood floors created some serious low frequencies up the mic stand as I was moving around. 
For some reason, the AM (amplitude modulated) radio static that I recorded recently is much noisier than the FM (frequency modulated) static. The noise is also at a lower frequency than the FM noise which makes sense since the FM band is at a higher frequency than the AM band. The AM band is in the kilohertz range (535 to 1705kHz) while the FM band is in the megahertz range (87.5 to 108 MHz). In any case, I think you will find this recording familiar. 
As I have mentioned in previous articles, I love knobs. This includes the tuning knob on AM/FM radios. For today’s sound I decided to record my old Panasonic tuner. I took a mono direct signal into my M-Audio Firewire 410 and started tuning. What I was after is that static sound between stations, and the tiny chunks of speech and music that pop through as one spins the dial. I started with FM, switched to AM, and then back to FM recording close to ten minutes worth of audio. This particular tuner wasn’t much good for producing the gliding theremin like tones you sometimes hear, but I got some good static and random micro-clips of music and speech. Here’s a snapshot of one of the sections I’m satisfied with.
