Abstract

The present disclosure discloses a directional propagation method and apparatus for audio signal, a terminal device and a storage medium. The method comprises acquiring a current location of a target user and audio data corresponding to the target user; propagating audio signal corresponding to said audio data towards said current location in a directional manner. By acquiring a current location of a target user in real time, this technical solution dynamically adjusts the audio data corresponding to the target user to be propagated in a directional manner towards said current location, wherein different audio data types (e.g. Chinese language audio or English language audio) may correspond to different target users, in such a way, it can be realized that different audio signals are propagated in a directional manner towards different locations.

Claims
