上篇(webRTC中语音降噪模块ANS细节详解(二))讲了ANS的处理流程和语音在时域和频域的相互转换.本篇开始讲语音降噪的核心部分,首先讲噪声的初始估计以及基于估计出来的噪声算先验信噪比和后验信噪比. 1,初始噪声估计 webRTC中ANS的初始噪声估计用的是分位数噪声估计法(QBNE,Quantile Based Noise Estimation),对应的论文为<Quantile Based Noise Estimation For Spectral Subtraction And Wien
Our team is developing an app to help people solve problem face to face. We choose webrtc protocol as our bridge among different platform(Android, iOS, browser etc). But there is a hole in Android 6.0 system, the protocol can not support Android 6.0

参考自:Introduction to WebRTC on AndroidAndroid之WebRTC介绍 WebRTC被誉为是web长期开源开发的一个新启元,是近年来web开发的最重要创新.WebRTC允许Web开发者在其web应用中添加视频聊天或者点对点数据传输,不需要复杂的代码或者昂贵的配置.目前支持Chrome.Firefox和Opera,后续会支持更多的浏览器,它有能力达到数十亿的设备. 然而,WebRTC一直被误解为仅适合于浏览器.事实上,WebRTC最重要的一个特征是允许本地和we
