Abstract
A response compensation method, an electronic device and a computer recording medium are provided, where the method is adapted to an electronic device having two non-coplanarly disposed speakers and includes the following steps. A stereo audio signal is respectively high-pass filtered and low-pass filtered followed by sound-field processing to generate a modified high-frequency right-channel signal, a modified high-frequency left-channel signal, a modified low-frequency right-channel signal, and a modified low-frequency left-channel signal. The modified high-frequency right-channel signal and the modified low-frequency right-channel signal are outputted to the first speaker, and the modified high-frequency left-channel signal and the modified low-frequency left-channel signal are outputted to the second speaker, where the modified high-frequency right-channel signal and the modified high-frequency left-channel signal are outputted diffusely by the two speakers, and the modified low-frequency right-channel signal and the modified low-frequency left-channel signal are outputted centrally by the two speakers.
