CB Radio - SquareCB Radio is a small collection of static produced by different channels on a 40-channel CB Transducer. Included in the collection are button sounds and antenna extension and contraction sounds. I found a pair of “Realistic TRC-222 40-channel Citizens Band Transceivers” at a second hand store, but only one works! Such is life. So here are the sounds the surviving “walkie-talkie” produces.

Recording Technique: This collection was a simple one. I used a Sony PCM-D50 in ORTF setup, recording at 96k/24bit. I just held the device up to the recorder and hit record, flipped through various channels. Super simple. I found that the static sound was very “static”… Duh, you might say. But when I touched the antenna it would attenuate the sound a bit. So most channels were recorded for ~30 seconds as is, and then again varying touching the antenna to give it a “breaking up” cadence. Those tracks are labeled “warble”.

For the button clicks and knob turns I took the batteries out of the CB transducer so that I could get them clean without any static. This includes a “channel button,” which shows you which channel you’re on; the talk button, like all walkie-talkies; the channel selector dial, which … selects the channel, and produces a clicking sound; and the volume dial, which also acts as an on/off switch. The “Battery Test” button sounded just like the channel button, so I didn’t bother. The antenna sounds were the biggest challenge as the antenna extends out 3 or 4 feet, so I tried to give enough variation in speed and force to meet all antenna needs. It was actually quite an awkward antenna. You couldn’t just pull it all the way out in one quick motion. I don’t think anyone could look cool and suave pulling this antenna all the way out. Not even Kurt Russell… And he’s a badass.

This collection provides some new and interesting sounds, as well as a ton of variations so your soundtrack never gets old! All Soundopolis tracks include metadata tags so they are easy to find using any search engine. All tracks were recorded, edited, mastered, and packaged as 96k/24bit wave files. This collection comes in one easily downloadable zip file.
