Abstract
A circuit for multiplexing three or more audio band electrical signals into two audio band electrical signals which can be provided to a stereo input and a circuit and computer method for demultiplexing the signals. In particular, six signals from the six strings of a guitar are multiplexed for stereo audio analog input to a sound card in a personal computer where the signals are digitized and then, using software running on the computer, demultiplexed into six signals from which the frequencies above 4.5 kHz have been lost.
