ABSTRACT:
An ambience processor receives and combines the left and right channel signals from a stereophonic amplifier. The resulting composite signal is converted to a sequence of digital signals which are stored in a random access memory. The stored digital representation of the composite signal is read out of the random access memory at different times to separate output circuits which drive left channel and right channel ambience loudspeakers. Reverberation effects are obtained by feeding back portions of the separate output signals to the input of the system.
