Audio signal optimization method and apparatus

The present disclosure discloses a voices signal optimization method and the apparatus belonging to the speech signal processing field. The method used comprises the terminal at least two sound collection unit, comprising: two sound collection unit of a sound source of the terminal periphery positioned at least by the; from each sound source localization determining the selected specified a sound source; the spatial position of the designated sound source localization obtained, determining the sound signal a sound signal of the terminal acquired emitted by the specified sound source; a sound signal to the specified sound source of sound volume optimization . The present disclosure in the acquisition of an audio signal, by filtering the surrounding sound source and the sound signal selected in the sound source is optimized, improving collection effect of the terminal of the sound signal.
