This sound is recorded directly from one of my original 1938 98cc light motorbikes. This time is a express (manufaturer) sl 102 (type). The noise you hear is all specific. It is the fuel cock on selection, the flooding of the carburettor, suction of the engine, two tries to bring the engine to live with clutch action inbetween. Running on idle and two short openings of the throttle. Engine is shut off by using the decompression lever which is typical for this period of time and two stroke engines. .
Two stroke diesel engine on a narrow boat on the river weaver cheshire - running at normal cruising speed. Audio track separated from a video. Camera was just in front of cabin - filming for most of the time towards the bow. The sound was captured when the camera was turned to film the two boaters at the helm.
Sound of a pickup truck. Keys jingle, door shuts, starter click, engine turns over and sits idle, tires roll over gravel slowly, then truck drives away. Normalization applied.
Recording of a passenger jet landing at zurich international airport. The recording was made approx 30meters below the aircraft as it came into land. 20kph west wind and rain. 96khz 24bit wav stereo.
Samples of the vintage korg mini pops 45 drum machine. No processing applied here but a very gentle fft based noise reduction. After all, i figured background noise was part of the machine's sonic identity. No patterns here, since that would have taken forever, just the individual sounds. Some of them alone, some of them combined. Recorded mono with a zoom h2n thru the machine's "amp" output.
