Audio signal processing for stereo headphone - adjusting stereo spectrum width or original audio signal and feeding back variable intensity

摘要

Starting from an arbitrary, original audio signal, its stereo sound spectrum width is variably adjusted. It is then fed back with a variable intensity to the original signal. The two signal components of the generated stereo signal are variably mixed, with a delay, feedback, and their intensity. Then the two signal components are passed through separately adjustable filters to simulate time dependent, variable, two-ear, outer ear transmission functions. The stereo signal components are several times, variably, intensity dependent delayed, frequency distorted and mixed for simulating three-dimensionally, directionally independent, localised room reflections. ADVANTAGE - Almost real, natural audio signal reception and reproduction by stereo headphones.
