Release notes

This page has the release notes for the following extensions:

• AI Noise Suppression
• Virtual Background

Agora charges additionally for this extension. See Pricing.

This release improves the calculation performance of the AI-powered noise suppression algorithm.

This release adds the following APIs and parameters:

• APIs:
  • checkCompatibility: Checks whether the AI Noise Suppression extension is supported on the current browser.
  • setMode: Sets the noise suppression mode as AI noise suppression or stationary noise suppression.
  • setLevel: Sets the AI noise suppression level.
• Parameters:
  • elapsedTime in onoverload: Reports the time in ms that the extension needs to process one audio frame.

For API details, see AI Noise Suppression.

This release brings the following changes:

• AI Noise Suppression supports Agora Video SDK for Web v4.15.0 or later.
• The extension has Wasm dependencies only. Because JS dependencies are removed, you need to publish the Wasm files located in the node_modules/agora-extension-ai-denoiser/external directory again. If you have enabled the Content Security Policy (CSP), you need to modify the CSP configuration. See AI Noise Suppression for details.
• The audio data is dumped in PCM format instead of WAV format.
• To adjust the intensity of noise suppression, best practice is to call setLevel.

First release.

v1.2.0 was released on December 10, 2023.

As of this version, the Virtual Background extension incorporates the necessary Wasm module. You no longer need to publish the Wasm file separately, and pass the wasmDir parameter when calling the init method to initialize the extension.

After upgrading to this version, please modify your code accordingly.

This release upgrades the background segmentation algorithm of the extension, optimizing the segmentation effects on the subject, edges, and fingers in complex static and dynamic backgrounds.

This release fixed the issue that checkCompatibility could return inaccurate results on specific devices.

The wasmDir parameter of the init method is now optional.

This release fixes the occasional issue of jagged background images on Chrome for Android.

You can now specify the fit property when calling setOptions. This sets how the background is resized to fit the container. For API details, see Virtual background.

Virtual Background supports Agora Video SDK for Web v4.15.0 or later.

You can now call checkCompatibility and test if AI Noise Suppression extension is supported on the current browser. For API details, see Virtual background.

A black bar is no longer displayed to the left of the virtual background.

You can create multiple VirtualBackgroundProcessor instances to process multiple video streams.
