低延时分布式音频处理方法及系统

Low-time-delay distributed audio processing method and system

Abstract

本发明公开一种低延时分布式音频处理方法及系统,其中,该方法包括如下步骤:从两个处理器中指定任意一处理器作为主处理器,另一处理器作为从处理器;接收经FPGA输送的音频信号;在主处理器上,对音频信号中的远端音频信号进行解码处理得到解码音频数据,并对解码音频数据进行音效处理生成第一音频数据,以及在从处理器上,对音频信号中的本地音频信号进行音频处理生成第二音频数据;将第一音频处理数据及第二音频处理数据传送至FPGA进行混音处理,并由FPGA对混音处理的第一音频处理数据及第二音频处理数据进行分发。本发明的技术方案能够降低音频处理延时,提高系统稳定性,能够给用户呈现更好的使用体验。
The invention discloses a low-time-delay distributed audio processing method and system. The method comprises the following steps that any one of two processors serves a main processor, the other serves as an auxiliary processor; audio signals transmitted via an FPGA are received; in the main processor, far-end audio signals in the audio signals are decoded to obtain decoded audio data, and sound effect processing is carried out on the decoded audio data to generate first audio data, and in the auxiliary processor, audio processing is carried out on local audio signals in the audio signals to generate second audio data; first and second audio processing data is transmitted to the FPGA for audio mixing, and the FPGA issues the mixed first and second audio processing data. The method and system can reduced time delay of audio processing, the system stability is improved, and better using experience is provided for users.
