Phase conversion surround circuitry |
摘要 |
A phase-conversion surround circuitry gives surround effects to right- and left-channel audio signals. An audio difference signal between the right- and left-channel audio signals is delayed at a specific time constant. The delayed audio difference signal is combined with the right- and left-channel audio signals, thus composite audio signals being generated. The time constant is periodically varying under oscillation at frequency of 12 Hz or less.
