音频降噪回声消除技术的应用

Application of audio noise and echo cancellation technology

针对音频降噪回声消除技术的应用展开探讨,从声学回声、电路回声以及VoIP通话的工作模式三个方面,简要介绍了回声消除技术,进一步探讨了音频降噪回声消除技术的实际应用要点。根据研究结果可知,在实际运用音频降噪回声消除技术的过程中,应从硬件、软件回声消除两个方面入手,并结合实际情况合理运用不同回声消除算法。

This paper discusses the application of audio noise reduction echo cancellation technology,introduces the echo can-cellation technology from acoustic echo,circuit echo and the working mode of VolP call,and further discusses the key points of practical application of audio noise reduction echo cancellation technology.According to the research results,in the actual ap-plication of audio noise reduction echo cancellation technology,we should start from hardware and software echo cancellation,and combine with the actual situation to reasonably use different echo cancellation algorithms.
