Process and apparatus for controlling acoustical or optical apparatuses

Abstract

Abstract 1. A process to initiate a control signal to control acoustic or optical equipment, particularly a slide projector or lighting system, by set parameters of a sound recording, characterized in that as parameters sets of data are used which are so produced in a plotting operation that particular points on the sound signal envelope curve of the sound recording are detected and prepared for digital storage, and that these sets of data are stored in a storage unit, typically operating as a ring-type storage unit, of a microprocessor (Fig. 4), that in the plotting operation when setting an item of control information for the optical or acoustic equipment the actual set of data contained in the ring-type storage unit is transferred with the control information as controlling mark into a main storage unit, and that in a functioning operation similarly prepared sets of data are compared with the stored sets of data from the plotting operation, and that when two sets of data agree the control signal is initiated.
