Abstract
An audio signal processing method and a mobile apparatus are provided. In the method, a target direction in multiple sound-reception directions and a target distance corresponding to the target direction is determined according to multiple first audio signals in the sound-reception directions received by an embedded microphone. A target algorithm is selected from multiple blind signal separation (BSS) algorithms according to the target direction and the target distance. The first audio signal received by the embedded microphone at the target direction is set as a secondary signal of the target algorithm, and the second audio signal received by an external microphone is set as a primary signal of the target algorithm. The audio signal of the primary sound source is separated from the primary signal and the secondary signal through the target algorithm. Accordingly, the microphone path merely outputs a single audio signal of the primary sound source.
