Gas boiler in my kitchen starts up, you can hear the piezo ignition inflaming the gas and the subsequent burning gas. This version is processed (compressor, eq). Recording by a zoom h2n.
This is a sample i made from a piano through a variety of processors. It sounds to me like a texture you may hear in a boiler room or some kind of ventilation system.
An mg-b being started and driving off on gravel. Minimal editing in audacity to fade out to minimise background noise. Recorded with a marantz pmd-661 with built-in microphones, for a delicate balance, oxford theatre guild 2011.
Sound synthesis made from chuck programming language. The model is a connection from an impulse generator to 40 digital filters to 40 delay linesand set feedback between each delay lines. Each delay lines's delay time and cutoff frequency is random. But there was an error in the calculation and the output value overflows. And this create a chaotic behavior in this sample. - - -. This one is a smooth rising soundwith alternating digital aliasing resonances at the end.
