Video Recording

Video Recorder

We have recently released video recording functionality (not to be confused with client side recording released by browser vendors) and there is a number of cases when it can be very useful. This tutorial explains how to use this new functionality to build video recorder web app using our Web SDK in minutes.

HD Audio Recording

HD_recording

We’ve been offering audio recording for a while, but our audio recorder was saving audio in 8KHz, since it’s the most used format in good old telephony and when we have calls to/from PSTN. When we work with VoIP endpoints that do support wideband audio (WebRTC, SIP, mobile SDKs) we can save audio with much better quality without downsampling it to 8KHz. We chose 48 KHz as the base sample rate for HD audio recorder, since WebRTC/Opus can offer this quality, audio from endpoints with lower sample rate will be re-sampled.

It’s easy to use HD audio recording, just add hd_audio parameter in the recorder params:

  1. // Example for the record method of the Call class function
  2. call.record({hd_audio: true});
  3. // Example for the Recorder class
  4. require(Modules.Recorder);
  5. // ...
  6. var recorder = VoxEngine.createRecorder({hd_audio: true});
  7. call.sendMediaTo(recorder);

Feel free to start recording your calls in HD today, wideband audio conferencing is coming soon, stay tuned!
