webrtc audio

Five lessons audio processing and DX Audio plug-in introduction Through the last lesson, you can record the singer's clean voice completely. The next step is to do audio processing for the clean vocals to get the best sense of hearing. Commonly used audio processing of the human voice generally includes the following

Recently experiment how to let WEBRTC support H264 code, record, for people who need reference.To illustrate, I was compiling the WebRTC under Ubuntu Server 14.04, using the native (c + +) API to develop WebRTC applications. So my adjustments are based on the native code.The end result is that the browser can send a video with H264 or receive H264 video.Note that

Recently, due to the needs of the project, I began to touch the WEBRTC thing. Unexpectedly the threshold of this thing is still pretty high, next share I stepped on the pit, hoping for the first contact with this thing in the future to help people.WEBRTC official websiteThe first step of course is to see the official homepage (www.webrtc.org), first the content of the homepage was roughly swept over, probably a little bit of understanding of this thin

Recently, our team is developing a 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 are a hole in Android 6.0 system, the protocol can not support Android 6.0 system.As we known, Libjingle (Http://mvnrepository.com/artifact/io.pristine) was built in December, 2015,It hasn ' t been updated in least one year. I do not know if

WEBRTC 's echo cancellation (AEC, AECM) algorithm mainly includes the following important modules: Echo delay estimation, NLMS (normalized minimum mean square adaptive algorithm), NLP (nonlinear filtering), CNG (Comfort noise generation). The General classic AEC algorithm should also include double-ended detection (DT). Considering that the NLMs, NLP and CNG used by WEBRTC belong to the classical algorithm

WEBRTC in the Chrome browser demo Many examples, WebRTC source, but in the Firefox browser, the example can not be used, the information on the web said to set the media.peerconnection.enabled to True, However, in the Firefox browser, the default value is True, using the WEBRTC example in Firefox or can not capture local video. Here are the examples found online:

WebRTC represents the best technology in the field of real-time communication since the date of birth. But for a long time, it supported the video encoder only VP8, and later with H265/VP9 as the representative of the birth of the next generation of video Encoders, WebRTC appeared VP9 Codec. The most widely used H264 has been kept out of sight. Until Cisco announces its H264 codec open source for OpenH264,
