- Analysis Summary
- Tests a Windows voice-call setting that reduces echo when speakers are used instead of headphones.
- Why It Matters
- Speaker calls can create echo when the other person’s audio is picked up by the mic.
- Splitting mix and auto lets Discord tune echo reduction with less impact on voice quality.
- Detailed Description
- This experiment changes how Windows voice calls handle speaker audio that can leak back into the microphone.
- The default uses mix, while variant 1 switches the echo handling mode to auto.
- It helps Discord compare which setting reduces echo without making voices sound worse.
