Embodiment Construction

[0027] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0028] In order to solve the problem that the codec resources of the modem module in the existing AP+modem scheme are not fully utilized, resulting in waste of resources, a method and device for processing audio data provided by the present invention aim to use the module virtual sound card , the codec in the modem module is virtualized as a sound card device; the AP and the modem module are connected through a Universal Serial Bus (USB, Universal Serial Bus), and the USB needs to virtualize at least two interfaces, one interface is used for audio control commands For interaction, an interface acts as the audio channel of the virtual sound card device. In this way, the AP can control the codec in the modem module to perform corresponding processing on the audio data through the USB, thereby making full use of the cod...

Abstract

The invention discloses a method and equipment for processing audio data. The method includes: an application processor (AP) is connected to a wireless (modem) module through a universal serial bus (USB), and a codec (codec) in the modem module It is virtualized as a sound card device through parameter configuration; the AP sends audio control commands to the modem module through the virtual USB command channel; the modem module controls the internal codec to perform corresponding processing on audio data according to the received audio control commands. The present invention can solve the problem that the codec resources of the modem module in the existing AP+modem scheme are not fully utilized, resulting in waste of resources.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an audio data processing method and device. Background technique [0002] With the popularity of handheld devices such as mobile phones and palmtop computers (pads), human beings have entered an era of extensive multimedia development. Among all kinds of handheld devices, audio equipment is indispensable, and sometimes the sound quality of the equipment is directly related to the positioning of the product price. [0003] In the prior art, many smart phones and pad products are designed using a solution of application processor (AP, Application Processor) + modem (modem) module. The modem module is usually also called the wireless module, and the modem module contains rich hardware resources, such as audio codec (codec), various rich peripheral interfaces, etc. In the design of audio solutions using AP+modem products, an external codec is mostly added as a sound ca...
