Pull Request Overview
This PR replaces the legacy AudioEngine class implementation with the new AudioEngineV2 WebAudioEngine class internally, while maintaining backward compatibility through the existing public API. The change reduces the babylon.js UMD package size by 2.92 KB by eliminating duplicate audio functionality.
Key changes include:
- Converting the legacy AudioEngine to a wrapper around the new _WebAudioEngine
- Adding support for enabling/disabling the unmute UI in the WebAudio implementation
- Refactoring audio destination and gain node management to be more flexible

This change replaces the old
AudioEngineclass's internals with the AudioEngineV2WebAudioEngineclass's implementation.This reduces the babylon.js UMD package size by 2.92 KB.
Note that this change only replaces the legacy
AudioEngineclass. More legacy classes will be replaced soon for more reductions in package size.Tested for regressions on all legacy audio engine doc playgrounds:
