output signal of the filter and the desired response, which is to ask for a gradient. The AEC algorithm in WEBRTC belongs to the piecewise fast frequency domain Adaptive filtering algorithm, partioned block Frequeney Domain Adaptive filter (PBFDAF).To determine whether the distal and proximal end of the conversation, also known as double-ended detection, the following four conditions need to be monitored:1. Only the far end to speak, at this time the

Webrtc packages criticalsection, which can be used in windows and posix platforms. The basic structure is as follows: In the factory method, you are responsible for the creation of specific class objects, which can be called a simple factory model. A factory is responsible for the creation of all products, different products are created by inputting necessary parameters to the factory. Generally, the created products are related and inherited from an

Previous notes, finishingWEBRTC uses UDP transport by default, but it can also be transmitted over TCP.With TCP transport, servers such as Turnserver,licode,janus and servers are required.1. If you use Turnserver, you only need the client to keep the relaytcp type of candidate, the others are discarded.2. If you are using a server such as Licode,janus, TCP is not supported by default.Because they are used at the bottom of the Libnice open-source Ice library, Libnice supports TCP in newer version

Implement The network communication protocol is not explicitly specified in the Voiceengine, so voice chat is not possible only by calling the Voiceengine API.

In the previous article (WEBRTC Audio-related Neteq (ii): Data structure) Neteq the main data structures, to understand the mechanism of Neteq lay a good foundation. This article is mainly about how the RTP packets received from the network in the MCU are put into packet buffer and taken out from packet buffer, as well as the calculation of the network delay value (optbuflevel) and the jitter buffer delay value (bufflevelfilt). Let's see how RTP voice

On csdn, I saw a new model of open-source news software: free software is not free. This concept is always described as "free", but not the true meaning of the word "free.Open source originated from free software ". This is also the first time most people hear the phrase "Free
