This morning at approximately 7:14 am roofers started removing four layers of asphalt tiles, along with the original cedar shakes, from the roof of my 102 year old house. Not being one to squander such opportunities, I recorded some of their hammering from inside the house. There’s some really nice wooden resonance to it. I hope you like it as much as I still am enjoying it. The photo is a detail from some of the debris that is collecting around the perimeter of my house. At this stage it was about 18″ deep.
Roof Racket
I can’t seem to get enough robot action these days. Robots have lots of personality. Much more than politicians who convene in St. Paul. I used a similar technique to get this sound as I did for 
I produced this sound by playing one note in a virtual instrument called “Harmonic Dreamz” which is part of 
I looped this section of radio static where I was quickly swapping between two channels of music with the analogue dial. Although cacophonous, it has a strangely attractive rhythmic and musical quality to it. So, of course that led me to experiment with some processing. I did not want to manipulate it too much so I could illustrate the drunken quality to the passage as it repeats, but I added a short, modulated, stereo delay to create some imaging on the mono recording. After that I decided to map a couple of controllers to the left and right feedback of the delay, allowing me to over saturate the output dynamically over the recording’s one minute and six seconds duration. 
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.
