High and Low Frequency Drone

This drone represents the fourth in my series of FM synthesis experiments. It has a variable high frequency buzz, not unlike a typical evenings chorus of cricket calls, and an underlying low frequency drone that that throbs gently throughout the duration of the audio. This selection was made from a pool of randomized sounds. It was edited out of the surrounding audio but not processed in any way other than the processing that was randomized within the instrument.

Quick and Dirty Ambiance from Hell

There are so many ways to use processing to make scary sounds that it’s almost too easy. The classic reverse reverb in the original Poltergeist comes to mind. This example is a recording of a conversation with a colleague during a lunch break at a busy sandwich joint. It’s been reversed, pitched down significantly, run through a low pass filter, slowly phased, filter delayed and run through a long reverb. All this processing has diffused the voices into a hellish ambient drone.

Ominous Synth Drone

I programmed a couple of parameters in a VST synth to a controller, set a single note (C1) to play for three minutes and eleven seconds, then recorded the automation. The parameters I was manipulating in real time were the shape of the waveform and the frequency. After recording the automation I added a bit of compression, a nice slow chorus to give it a left to right sweep, and a short delay with a lot of feedback for some added atmosphere. The image is just a snapshot from my photos and has nothing to do with the sound, but you’ve gotta love stick figure warning messages.

Synthesizer Fifths Drone

I added some delay to spread the stereo spectrum on this synthesizer drone of a low frequency fifith interval. During the recording you can hear the cutoff frequency changing as I turned the knob for it. On my most often used synth, the Korg MS2000 that was used for this recording, the surface around the cutoff frequency knob has been polished smooth from wear. I use it much more frequently than the modulation wheel or pitch wheel. I love knobs.
