I've always enjoyed the whitenoise of HVAC systems. It was always pleasant in college to find empty classrooms after-hours, with just the whirr of the HVAC.

- LVB 14y agoMe too. I found this pack of high-quality recordings of various fans and blowers: http://www.freesound.org/people/Stomp/packs/990/ http://www.freesound.org/people/Stomp/packs/990/ I loop my favorite samples which makes for a nice background.
- brittohalloran 14y agoYou want a Marpac 980 white noise maker. It's a little fan in a box with tone adjustments (no speaker involved). Amazing white noise.

- n2j3 14y agobeautiful! but how does it work? can we look at the source without decompilation?
- logn 14y agoNo unfortunately not. Maybe I'll put it on my GitHub soon. I was thinking maybe I'd find some way to make money on this, so I haven't released the source yet. As to how it works, internally there's a modular data processing pipeline. I wrote a number of modules that serve a specific purpose (sine wave, square, etc, and reverb, gain, etc). They all get connected together in a driver class. Each driver makes heavy use of random numbers. Those in turn decide the notes played and durations. The durations are extremely short, leading to a granular synthesis of sorts. The notes are chosen from classes I structured around standard chord theory and classical modes. I have an unreleased version that processes mic input, but it's not ready for prime time yet. Edit: I decided to release it, probably under AGPL license.
