- Fix RNNoise configuration: use mono instead of stereo, increase VAD threshold to 95% - Adjust quantum settings: increase min-quantum to 64 for stability - Add comprehensive voice distortion troubleshoot script - Create optional disable-auto-rnnoise.nix for problematic setups - The automatic RNNoise filter can cause artifacts, script helps diagnose and fix
