ABSTRACT:
An analog vector processor and method for converting right and left mono and stereo audio input signals through a series of six amplifier blocks and two control blocks using a series of unique signal path connections. The six amplifier blocks are comprised of three dual-amplifiers, two spacial amplifiers, a four-amplifier integrated circuit that inverts and transposes the signal path thus putting the signals out-of-phase. The two control blocks are comprised of a new and unique signal mixer control block that selects a mono, stereo, spacial or binaural signal, and a level control block for dual tracking of the signals. The resultant output signals are of an altered sound field producing a binaural effect thus creating a three-dimensional sound experience. The input signals may be from any sound source or conducting medium.
