Audio processing method, device and system

音频处理方法、装置及系统

Abstract

The invention discloses an audio processing method, device and system. Speech signals collected by a microphone array are converted into multiple channels of digital signals through an ADC to be input into an FGPA chip or MCU chip, left channel data and right channel data in the multiple channels of digital signals are sequentially received by the FGPA chip or MCU chip, and after caching is conducted on the left channel data and the right channel data for a preset period of time, a single channel of digital signals containing synchronous recognition signals are output to an audio processor, and data are restored by the audio processor to each channel for audio processing. According to the audio processing method, multiple channels of front-end input digital signals are processed into a single channel of digital signals through software or hardware, and then the signals are output to a back-end processing system, so that the compatibility of system design is improved and development cycle and cost are reduced.
本发明提出一种音频处理方法、装置及系统,首先由ADC将麦克风阵列拾取的语音信号转换成多路数字信号输入FGPA芯片或MCU芯片,由FGPA芯片或MCU芯片依次接收所述多路数字信号中的左通道数据和右通道数据,并对所述左通道数据和右通道数据分别缓存预设时间后,输出带有同步识别信号的单路数字信号至音频处理器,由音频处理器将数据还原至各通道进行音频处理。本发明的音频处理方法通过软件或硬件方式将前端输入的多路数字信号处理为单路数字信号后输出至后端处理系统,提高了系统设计的兼容性,节省了开发周期和成本。
