ABSTRACT:
Apparatus for projecting movement of audio signals employs a plurality of variable-gain amplifier stages, the gain thereof being controlled by the states of an associated plurality of counters and decoders, to provide a spatial distribution of audio signals in such a manner that the signals are perceived as having a variety of geometric configurations, which configurations may be either dynamic or static. The apparatus is suitable for use with recorded or "live" audio signals. Various alternatives are also disclosed, including a sequencing circuit for allowing automatic variation of amplifier gain in response to various components of the audio signal itself. The apparatus may be configured for connection directly to power amplifiers, or for connection to recording devices.
