WebRTC Audio Delay Fix

I'm looking for a WebRTC expert to diagnose and fix an audio delay issue in our streaming application. The system is built using:

- React.js (frontend)
- Node.js + Mediasoup (media server)
- Python + aiortc (audio processing)
- WebRTC

The suspected cause of the delay is within the Python + aiortc audio processing.

Ideal Skills and Experience:
- Deep understanding of WebRTC
- Proficiency in Python, especially with aiortc
- Experience with audio processing and streaming
- Familiarity with Node.js and Mediasoup
- Problem-solving mindset and ability to work quickly, as I need this done ASAP

Please share your relevant experience and approach.
