ZEGOCLOUD Web SDK: Empowering Real-Time Experiences

In the current digital wave, the demand for Web end audio and video applications is experiencing explosive growth. Whether it’s 1V1 stranger dating, live streaming shows, or e – commerce live streaming, these scenarios have put forward higher requirements for the quality and stability of real-time audio and video communication.

Prominent Advantages of Web-end Applications

Web – end applications have many remarkable advantages. It can be updated extremely fast. Unlike native applications, it doesn’t need to wait for the long – drawn – out review and release process of the app store, and new functions can be updated and launched at any time. At the same time, the development cost is lower, and the development cycle is shorter, which greatly saves the time and capital investment of enterprises. Moreover, H5-end applications are SEO-friendly and can be indexed by search engines, effectively enhancing the application’s exposure and search ranking, thereby improving promotion and monetization efficiency.

Given these advantages, Web – end applications are especially suitable for developing lightweight applications and products that require rapid iteration. On the other hand, the evolution of emerging Web forms such as PWA and Telegram Mini App has also given enterprises more opportunities to reach more users and enhance user stickiness by reducing jumps and simplifying processes. With the development of the industry, Web – end applications are occupying an increasingly large proportion of traffic and revenue in various popular business scenarios.

However, if these applications want to conduct real-time audio and video calls or live streaming, they rely on the capabilities of Web-end RTC. For enterprises, the Web-end SDK of cloud service providers like ZEGOCLOUD is a very good choice.

ZEGOCLOUD Web SDK: Powerful Features for Real-Time Communication

ZEGOCLOUD has years of industry experience and profound technical accumulation. It is committed to providing customers with high – quality real – time interaction experiences, helping enterprises quickly build real – time audio and video communication capabilities in various scenarios, and promoting the rapid launch of applications. Especially on the Web – end, it has polished in – depth and comprehensive core product functions, expansion capabilities, and scene solutions, and its experience is comparable to that of the native end.

ZEGOCLOUD Web SDK Core Product Capabilities

1. Network Adaptation and Optimization

It supports functions such as large and small streams, traffic control, and automatic switching of audio and video. The streaming end can simultaneously push two streams with different resolutions and bitrates, and the receiving end can freely choose to pull high – resolution or low – resolution streams according to its own network environment, effectively coping with complex overseas networks. At the same time, when the network quality of the streaming end changes, it can automatically adjust the bitrate, resolution, and frame rate of the media stream to ensure smooth interaction. In extreme cases of poor network conditions, it supports giving priority to audio transmission to ensure smooth communication. Once the network situation improves, it will be upgraded to video transmission and pull high-resolution streams.

2. Excellent Sound Quality

The ZEGOCLOUD Purio AI audio engine has scene – based AI noise – reduction capabilities. It can reduce the noise of the sound collected by the microphone. It can not only handle steady state noise but also non-steady state noise such as mouse and keyboard sounds, kitchen dish sounds, environmental wind sounds, and coughing sounds. Moreover, the CPU consumption is much lower compared to traditional noise reduction. The Purio AI audio engine also supports multiple vocal beautification effects, spatial audio, and precise routing, bringing users a purer, more authentic, and more comfortable auditory experience.

3. Ultra – Clear Video Quality

Self – developed H.265 and H.264 encoders offer high compatibility with low – end devices. They support adaptive encoding formats and can automatically downgrade to H.264. The SDK also supports adaptive clarity, adjusting the optimal picture quality according to the actual network situation. Additionally, it supports 4K resolution and 60fps, enabling the advanced features of different devices to be fully utilized.

4. Background Optimization

It supports background replacement. When users or anchors are in complex environments, they can replace the background or virtualize it. They can also change the background according to needs, such as singing, outdoor, online meeting, etc., making the communication environment more in line with user requirements.

5. Live Streaming

The self – developed Interactive live streaming, based on six high-quality features of ultra-low latency, super-strong synchronization, resistance to extreme weak networks, ultra-low lag, ultra-clear image quality, and instant first-frame opening, creates an ultimate experience. It supports a complete multi – person cross – room PK solution and a cross – App PK solution. It supports smooth switching from CDN to L3 streaming.

6. In – app chat

Based on ZEGOCLOUD’s years of real – time interaction technology accumulation, it realizes global interconnection. Once connected, it can achieve complete IM capabilities such as one – on – one chat, group chat, session management, group management, call invitation, and content review. Combined with the RTC product, it uses IM signaling to solve business difficulties such as call logic and billing and timing in complex audio – video call scenarios. It supports call invitations and offline push channels of multiple vendors, simplifying the integration complexity of push channels.

7. Content Review

It provides real-time security review services. Developers can call the audio-video stream review interface to detect in real-time whether there is any illegal content in the stream. ZEGOCLOUD will send the illegal information to the URL specified by the developer through a callback, assisting the business in supervising the safety of user rooms and reducing the cost of manual review.

8. Cloud Recording

Through simple cloud recording API integration and call, it helps developers quickly implement the recording function of audio – video calls and interactive live streaming, facilitating the playback of recorded content.

In addition, the ZEGOCLOUD web SDK also supports basic beauty functions, providing multiple beauty capabilities such as whitening, skin – smoothing, and sharpening, as well as functions such as real – time voice changing, mixing, and screen sharing, providing users with a higher – quality interactive experience.
