openclaw - 💡(How to fix) Fix Google Meet Chrome realtime bridge should support higher-fidelity PCM audio [1 comments, 2 participants]

TL;DR

Implementing a higher-fidelity audio path, such as PCM16 at 24 kHz or 48 kHz, for Google Meet Chrome mode can improve audio quality.

Guidance

• Investigate the feasibility of adding a new audio format to the Chrome/Meet bridge, such as PCM16 at 24 kHz or 48 kHz, to support higher-fidelity audio.
• Consider maintaining the existing 8 kHz mu-law path for compatibility with telephony/Twilio, while allowing Google Meet Chrome mode to negotiate and use the higher-fidelity path.
• Evaluate the impact of resampling audio from 48 kHz to 16 kHz for Gemini input and determine the best approach to minimize audio quality degradation.
• Research the requirements for implementing a new audio format in the Google Meet Chrome mode, including any necessary changes to the Chrome audio input/output commands.

Notes

The implementation of a higher-fidelity audio path may require significant changes to the existing audio processing pipeline, and careful consideration should be given to ensuring compatibility with existing systems and minimizing audio quality degradation.

Recommendation

Apply a workaround by implementing a higher-fidelity audio path, such as PCM16 at 24 kHz or 48 kHz, to improve audio quality for Google Meet Chrome mode, while maintaining the existing 8 kHz mu-law path for compatibility. This approach allows for improved audio quality while minimizing the risk of disrupting existing functionality.
