AU8 transforms ambiance-noise to stereo sounds.

A membrane receives sound waves and passes them to 3 equally tuned strings. An electro-magnetic pickup converted the string-vibrations into electric signals. The signals are amplified and passed on to a line-out, where headphones and recording-devices can be plugged in.

AU8 works in stereo. The pickups sit on both sides of the membrane. Both signals are amplified separately.
