Inserting a 5. 25-inch floppy disk into a micropolis 1053 i metafloppy floppy-disk drive. That's the sliding sound at the beginning. The second knock-knock type of sound is the press-down-and-hook drive latch being closed. The micropolis 1053 is a two-drives unit for s-100 bus early computers. This sound was recorded on the upper floppy-drive.
Ambience of interior of a minivan driving. Accelerate, drive, blinkers, turn, decelerate. Quad recording - l,r,ls,rs. Recorded with the zoom h2n in surround mode.
This is record from line-out of soundcard connected to microphone in, when command "sudo cat /dev/sda1 > /dev/dsp" is running in my linux command line shell. Sounds really close to modem 56k. Unfortunately i've written it into 128 kbit mp3, so this is result of back conversion into wave.
Recorded with sony pcm-m10 with a shure sm-58 microphone in the engine compartment. Took a short drive, max speed aprox 50 km/h. Various sounds, idling, driving, acceleration.
