ABSTRACT:
A telephone interface system for the transmission and reproduction of an audio performance, particularly a musical performance, at separate locations utilizing an amplitude modulated carrier frequency is disclosed. The system serves to both transmit a performance at one instant location to one or more remote locations and to receive and reproduce a similar performance from the remote location(s) transmitted to the instant location. The performer(s) at a first location each hear the audio output of the performance(s) at the other location(s) as though such other performer(s) were actually present at the first location and vice versa.
