HD Audio Conferencing

HD Audio Conference

We were quite busy working on HD audio conferencing support and now it’s available for all VoxImplant developers. In HD mode audio is being mixed at 48KHz, all audio sources with lower sample rate will be resampled to 48KHz. Web and mobile SDK uses Opus audio codec and offers the best possible audio quality. Up to 100 participants can be connected to a conference.

It’s simple to enable HD mode for a conference in VoxEngine scenario:

// HD mode can be enabled for the conference by passing hd_audio parameter set to true
var conf = VoxEngine.createConference({ hd_audio: true });

You can learn more about building audio conferencing services using VoxImplant in our tutorial. HD audio conference demo available at https://demos.voximplant.com/hdconf/ (optimized for WebRTC browsers) , the demo app source code is available at https://github.com/voximplant/voxhdconf

Click-to-call for web and mobile application

One of the most popular scenarios for our Web/Mobile SDK is about enabling true click-to-call/tap-to-call function in web and mobile applications. True click-to-call means that it’s not about callback version when a call is initiated from the platform to both parties and connects them together, it means that call is initiated from the client side and goes via IP to the platform and then routed to required destination. True click-to-call is cheaper, faster and offers better UX; of course, you need to have the internet connection to use it (shouldn’t be an issue these days). This tutorial explains how to easily embed click-to-call into your app using VoxImplant SDKs and setup call routing using VoxEngine scenarios.

We recommend to check our Quickstart before you proceed
