Abstract:
1. A method of creating a surround experience for headphones, the method comprising: receiving a first input audio channel signal and a second input audio channel signal; splitting each of the first and second input audio channel signals into a high-pass audio signal and a low-pass audio signal; cross-mixing the low-pass audio signal of the first input audio channel signal and the low-pass audio signal of the second input audio channel signal; adjusting each of the low-pass audio signals by applying artificial reverberation, wherein the applying artificial reverberation comprises applying a different delay profile to each of the low-pass audio signals; adding the high-pass audio signal and the adjusted and cross-mixed low-pass audio signal for each of the first and second input audio channel signals to generate a first output audio channel signal and a second output audio channel signal.
