Abstract
Abstract An arrangement for synchronized recording is described for recording of a plurality of aural sounds in a predetermined time relationship. The arrangement includes a master tape player and a plurality of slave tape players which are controlled by a synchronizer so that they are individually advanced or retarded in accordance with a synchronizing signal from the master player. This enables the production of a single tape with each desired aural sounds on one of the multiple tracks of the tape in proper synchronized relationship.
