We periodically run a dare (friendly competition) at Freesound.
For the current dare we would like to use tape sounds - Any sound coming from tape is acceptable: cassette, microtape, reel-to-reel, even sound from video tapes.
Of course, sounds must not be a copyright infringement.
If you are interested to contribute sounds, please read here so you know how to tag and describe them.
Also please post on the dare thread to let me know you have submitted sounds so they can be moderated quickly.
