Abstract: A new method is proposed that produces stereophonic sound image out of monaural signal within a selected frequency regions. The system employs a strictly complementary (SC) linear phase FIR filter pair that separates input signal into different frequency regions. A pair of comb filters is applied to one of the filter's output. This implementation allows a certain frequency range to be relatively localized at center while the other sounds are perceived in a wider space.

Abstract: A method of converting single channel audio (mono) signals to two channel audio (stereo) signals using simple filters and an Intra-aural Time Difference (ITD) is presented. This method does not distort the spectral content of the original signal very much, and has low computation requirements. A variation is proposed which also uses Intra-aural Intensity Difference (IID).
