Todo List

• Read changed files to understand modifications
• Analyze AudioContext interaction changes
• Check for bugs and security issues
• Provide review feedback

Review Summary

The PR adds latencyHint: "interactive" to AudioContext constructors in both audio processing files:

• js/hang/src/publish/audio/captions.ts:86-89 - AudioContext for captions processing
• js/hang/src/publish/audio/index.ts:108-111 - AudioContext for main audio capture

Findings

👍 No bugs or security issues found.

The changes are appropriate for real-time audio processing:

• latencyHint: "interactive" optimizes AudioContext for low-latency scenarios
• Both contexts are properly cleaned up with effect.cleanup(() => ctx.close())
• Consistent application across both audio processing paths
• No security implications from this change

The author is correct that this is "basically a no-op but worth doing anyway" - it's a performance optimization hint that browsers may use to reduce audio latency, which aligns well with the MoQ protocol's real-time streaming goals.

✅ Approved - Good optimization for real-time audio.
