This sound is the seventh entry in my series of FM synthesis experiments. There are some very strange high frequency overtones audible in the first half of the sound. If you can bear the high frequencies, I suggest looping this sound and then listening to it for about thirty minutes.
As you listen say to yourself, “I will stop smoking cigarettes. I will stop smoking cigarettes.” If you are a non-smoker afterward and were not a non-smoker before, let me know and we’ll start a business.

Number six in my series of FM synthesis experiments is a grainy, low frequency stomach growl that makes me imagine subterranean seismic activity. For this example I played a randomized patch three times at different positions on the keyboard while exploring the patch. 
Number five in my sequence of experiments with FM synthesis is a bit noisier than the previous entries which is typical of sounds produced by randomizing parameters. Most of these I leave by the wayside, or edit specific parameters to make them more usable. However, this sound endeared me with is dirty and gravely characteristics. It caused me to imagine some scientific device of the future capable of materializing products or replicating a potato in a manner of seconds. This is the sound of that hypothetical device. 
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.
