Description

Optimize audio processing, prevent memory leaks, and improve UI responsiveness in Realtime V2.

Tasks

• Move audio processing to Web Worker to prevent UI blocking (MainV2.vue:511-529)
• Add throttling to audio level calculations (MainV2.vue:545-554)
• Fix memory leak risks in audio buffers and session objects
• Optimize synchronous audio data processing in event handlers
• Implement proper cleanup in onUnmounted lifecycle hook
• Add performance monitoring for audio processing

Priority

Medium

• Audio data processed synchronously in event handler could block UI thread
• Audio level calculation runs on every frame without throttling
• Memory leak risk identified in code review
