Abstract

The present invention relates to the field of audio signal processing, and discloses a method, system and apparatus for playing audio. The method comprises: receiving an instruction for playing a first audio item; determining, according to a source application of the first audio, a first sound card, wherein the first sound card is a sound card in an electrical device matching the first audio item; sending, to a digital signal processor (DSP) in the electrical device, a digital signal of the first audio item via the first sound card, wherein an analog signal of the first audio item is obtained after digital-to-analog conversion by the DSP; and controlling the DSP to send the analog signal of the first audio item to a first speaker, so that the first speaker plays the first audio, wherein the first speaker is a speaker in the electrical device matching the source application. According to the present invention, when multiple audio items are to be played simultaneously, one speaker can play one audio item, such that the audio is highly recognizable, improving a hearing effect.

Description

technical field [0001] The present invention relates to the technical field of audio signal processing, in particular to an audio playback method, system and device. Background technique [0002] Today, audio is widely used in various scenarios. For example, in order to enrich the experience of passengers during the vehicle journey, popular music, audio from Internet radio stations or audio from traffic announcements, etc. are usually played on the vehicle. In order to provide navigation tips to the driver, navigation audio may also be played on the vehicle at the same time. [0003] When playing audio, the CPU (Central Processing Unit, central processing unit) on the vehicle can obtain the digital audio signal of each audio to be played, which can include navigation audio, pop music, etc., and then, the CPU can drive instructions according to the sound card The transmission parameters control the sound card to mix each digital audio signal, and transmit the mixed digital ...
