Why has Google Meet audio latency increased to 2 seconds in group calls?

Introduction

Google Meet's audio latency increase to 2 seconds in group calls is a critical issue that demands immediate attention. This problem directly impacts user experience and could lead to decreased engagement and potential user churn. I'll approach this analysis systematically, focusing on identifying the root cause, validating hypotheses, and developing both short-term fixes and long-term solutions.

Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking this might be a recent change. When did you first notice this 2-second latency increase?

Why it matters: Helps pinpoint potential causes related to recent updates or changes. Expected answer: Within the last week or two. Impact on approach: Recent timing would focus our investigation on recent changes or updates.

• Considering user segments, I'm wondering if this affects all users equally. Are there any specific user groups or regions more affected by this latency issue?

Why it matters: Identifies if the problem is global or localized, helping narrow down potential causes. Expected answer: The issue is widespread but more pronounced in certain regions. Impact on approach: Regional differences could point to network infrastructure or server-related issues.

• Given the nature of group calls, I'm curious about the call size impact. Does the 2-second latency occur in all group sizes, or is it more prevalent in larger groups?

Why it matters: Helps determine if the issue is related to call complexity or server load. Expected answer: The latency is more noticeable in larger group calls. Impact on approach: This would suggest investigating scalability issues or resource allocation problems.

• Thinking about recent product changes, have there been any significant updates to Google Meet's audio processing or network protocols recently?

Why it matters: Recent changes could be directly related to the latency increase. Expected answer: A new audio codec was implemented last month. Impact on approach: This would focus our investigation on the new codec and its integration.
