ABSTRACT:
The three dimensional audio system may have an audio terminal and a computer input terminal in communication with multiple routing relays. The routing relays may be in communication with a volume calibration control that may be in communication with a volume control and a mute switch. The output of the volume control and the mute switch may be communicated to a variable compressor. The variable compressor may be in serial communication with a digital delay element, a first equalizer and a first variable crossover. The variable crossover may be in serial communication with a second delay element and a second equalizer and in communication with a frequency balance and mix element. The second equalizer may be in serial communication with a frequency balance and mix element that is in serial communication with a phase adjustment element and an output terminal. There may be front and rear elevated speakers.
