A collection of buttons and motor sounds recorded from a Sony TCM-939 cassette tape deck.

Useful for UI design, mechanical sound design and all manner of everyday switches. Recorded at 96 kHz these recordings sound amazing pitched down to become big mechanical noises.

Includes transport buttons, motor sounds, tray opens and closes, tapes in and out and the deck in operation from exterior and interior perspectives. Also present are cassette and tape case handling sounds.

Almost all the sounds were recorded using a mono DPA 4060 omni mic at very close range for details and a Sennheiser MKH 40 for a more overall sound.

The miniature size of the DPA 4060s means that there are numerous takes of the machine running recorded from inside the tape tray, which results in amazing close details of the motor and buttons.
