摘要:
A method for blind source separation based spatial filtering on an electronic device includes obtaining a first source audio signal and a second source audio signal. The method also includes applying a blind source separation filter set to the first source audio signal and to the second source audio signal to produce a spatially filtered first audio signal and a spatially filtered second audio signal. The method further includes playing the spatially filtered first audio signal over a first speaker to produce an acoustic spatially filtered first audio signal and playing the spatially filtered second audio signal over a second speaker to produce an acoustic spatially filtered second audio signal. The acoustic spatially filtered first audio signal and the acoustic spatially filtered second audio signal produce an isolated acoustic first source audio signal at a first position and an isolated acoustic second source audio signal at a second position.
