Bobcat Jackhammer Attachment

Wednesday, April 22, 2009 was a beautifully sunny day in Minneapolis. This quarter my schedule includes a three hour break, which I usually use for catching up on curriculum, ACB entries or meeting with students, but this time I let Spring fever take hold and got on my bike a rode around one of my favorite city lakes. There’s a nice spot on the lake where I sometimes read or take an afternoon nap. Unfortunately just across the lake from my spot was a work crew using a jackhammer to break up a cement driveway. If you can’t beat ‘um, join ‘um right? Having my PCM-D50 along, I finally gave up on the idea of a few Zs and rode over to the action to make a recording. It took a minute to get the levels right, but I think they were going to be at it all day, so there was plenty of time for a good long recording. Here’s a few passes of the jackhammer engaged and splitting concrete.

Freesound.org Loop

One thing I often do when illustrating to my students the breadth of sounds available on Freesound.org is to start looping multiple sounds simultaneously to instantly create a new sound piece. I never really bother capturing these, but recently I routed the output to Pro Tools as the loops were going in Freesound and got this result. The sounds used can be found here.

Earlier Freesound.org Loop

Here’s an earlier example of a loop from Freesound.org that I produced for my class in the same fashion as the example that I described in Freesound.org Loop. I’d love to hear other examples of these, so if you have them, please post them in a comment.

The Janitors Sink

Until now the sounds presented on ACB have included just about everything except the janitor’s sink. So here it is, recorded in the Grandpa-George building, just outside their studio space. This is the sound created by the plumbing resonating as the hot water runs through the pipes. Apparently the sound doesn’t happen with cold water, and it takes a minute for it to happen with the hot water turned on. For some reason the pipes don’t resonate unless they have hot water running through them. Derrin played the sink while I recorded the results on the Sony PCM-D50.
