Abstract

An expansion method of multi-channel panoramic audio effect is disclosed, which comprises first reading a two-channel stereo sound source signal and using Hafler technology to expand the stereo sound source signal into audio signals of five channels including a left-front channel, a right-front channel, a front-central channel, a left-rear channel, a right-rear channel; then generating the residual sound like echo from the left-rear channel and the right-rear channel by the residual sound technology; and finally delaying the left-rear channel and the right-rear channel for a first duration, and moving up the front-central channel for the second duration, so as to emphasize the audio effect of the front audio field and human sound significantly, thereby accomplishing the purpose of 3D audio effect for the listener to experience personally.
