Frequency Modulated Drone Generator


I’m currently working on a sound design project for a client who is looking for a way to generate specific sorts of sounds using easy to understand controls. I started by creating a frequency modulated drone generator. The tool has a mixer with six preset pitches plus noise. I also included amplitude modulation, with sliders to control the amount, LFO, and a frequency multiplier to allow for FM synthesis effects. Here’s an audio example that illustrates the range of sounds possible with this set of fairly simple and intuitive controls.

Book Ideas for a Sound Design Class?

I am excited to have the opportunity to teach an upper level sound design class to digital film students this Fall. I have several books in my collection that relate to sound design that cover very specific topics, but what I’ll need for the class is a book that covers a broad spectrum of concepts within the field. The course competencies include multi-tracking, mixing, sampling techniques, signal processing, equalization, editing, synchronization of audio and video, Foley, and ADR. Does anyone have any suggestions for a book focused on sound design, but general enough to cover all of these topics?

To give you an idea of what I’m looking for, I currently use Real World Digital Audio by Peter Kirn for an entry level audio production class that is a prerequisite for the sound design class. Peter’s book works really well because it’s current and covers exactly what I wanted for the audio production class in an illustrated, thorough, yet clear and concise way.

Four Oscillator Drone Produced with the WSG


What good is a Weird Sound Generator if you’re not using it to make weird sounds? Sometimes it is nice to just hold it on your lap and stroke it gently. That aside, it’s quiet useful once you plug it in and start twiddling the knobs. Here’s a piece I created by tuning the each of the four oscillators on the WSG and then fiddled with the filters. At the same time I made some adjustments to a phaser that I was running it through in Ableton Live and topped it off with ping pong delay.

Weird Sound Generator

This weekend I completed building a Weird Sound Generator, or WSG, component kit from Music From Outer Space. The kit comes with a printed circuit board and all the electronics, including resistors, capacitors, diodes, ICs, potentiometers, switches, and wires. The rest, like the housing, faceplate, and soldering is up to the builder.

I built a box similar to the recommended specifications and cut the faceplate out of an old computer case. The wood I used was scraps that I held onto and recycled. In fact, I managed built the entire instrument without buying anything beyond the kit itself. Even the stain, nails, glue, screws, and backing board were materials that I had hoarded from previous projects over the years.

It took me about thirteen hours to complete. But, it was a fun thirteen hours of playing with my soldering iron and power tools while following instructions, or coming up with a way to cut through metal, or mount a nine volt battery inside an already cramped case. And, although the case isn’t perfectly square, and the leads are more than a bit tangled, I’m pleased with the little noise maker that I now have at my disposal. In the next entry I’ll illustrate the sequence of events that took place in building this device. Oh yeah… and sounds.

Experimental Music Mondays Call for Entries

I am curating a series of Experimental Music events hosted by the Kitty Cat Klub in Minneapolis, Minnesota. The first installment is Monday, March 1st, 2010. Subsequent installments are scheduled for the last Monday of every month. For the first show we have three performances.

Ostraka (myself) with Graham O’Brien on drums will be performing using the GMS. Terr the Om (Nathan Brende) will also be performing his distinct breed of electronic music, melding the output from his circuit bent toys with looping and real-time arranging in Ableton Live. Thirdly, Dialsystem consisting of brothers, Graham and Casey O’Brien will likely mesmerize listeners with their ethereal mix of bass, drums, and electronics. Music starts at 9:00pm.

I’m in the process of booking the upcoming events, so if you are a performer of experimental music and would like to get involved, please send your name, artist name, contact information, links to a biography, and links to audio examples to emm [ at ] audiocookbook [ dot ] org.
