Opus话音编解码器关键技术研究

Study on the Key Technologies for Opus Audio Codec

随着多媒体技术和网络通信技术的不断发展,更高的音质和更低的码率必将成为未来话音编解码技术的发展趋势。Opus话音编解码器以开放源码、版税免费、高质量、低带宽开销、低延迟和鲁棒性强的特点,实现了兼容语音通话和立体声流媒体的高效、宽频带音频编解码功能。本文主要研究了Opus编解码器的关键技术及特点。

Along with the developing of multimedia technology and network communication technology,the higher audio quality and lower bit rate will become the development trend of audio codec technology in future. With the advantages of open source,free of charge,high quality,low bandwidth,low delay and strong robustness,the opus can process audio input with wide frequency from human voice to multimedia stereo. This paper mainly studied the key technology and characteristics of Opus Audio Codec.
