Motorboat running, increasing in speed then steady. Water sloshing and some birds. Eventually slows and heavy wave sound. Engine revving and sputtering at end.
Sounds like a power on sound. Made from a beep with a sine waveform (the hz of which increases), and bitcrushing it at 4 bits per sample and a sample rate of 40khz.
Recorded the 20th of january, 2020 in las vegas, nv on a tascam dr-05x internal mics. A semi truck without a trailer was passing by as i started the recording.
A few minutes of sparkly fresh water lapping on the seaside. There are a few occasional aural intruders, such as the low rumble of an engine in the distance.
Train arriving at station with some brake squeal and loud engine hum, interspersed with compressor hisses. At 1:15, the train revs up and departs again.
Sound of air brakes squealing and releasing. Recorded from a garbage truck with the iphone voice memos (i know, i know, but it actually sounds amazing).
The ambient noise of a parking lot at a walmart store, dominated by the throaty sound of a truck's engine. Carts rolling, cars starting up, etc. Recorded with the zoom h4n.
Strange machine thumping sound. It is the sound of an old malfunctioning tv monitor with all image adjustments knobs turned to the max. I was afraid it might implode. . . Credits listenjoe.
