Integration GroupAudioRouter dans AudioBridge pour routing bidirectionnel Modifications AudioBridge.js: - Ajout GroupAudioRouter pour matrice routing multi-canaux - Flux CAPTURE: Carte Son → GroupRouter → Groupes → LiveKit - Flux LECTURE: LiveKit → Groupes → GroupRouter → Carte Son - Conversions PCM Buffer ↔ Float32Array pour routing - Support multi-canaux (32+ canaux inputs/outputs) - Events groupAudioOut/groupAudioIn pour pont LiveKit Nouveau LiveKitServerBridge.js: - Pont entre AudioBridge et LiveKit SFU - Generation tokens JWT pour clients - Gestion rooms par groupe - API list participants/create room - Events pour debug/monitoring Documentation AUDIO_BRIDGE_ARCHITECTURE.md: - Architecture complete flux audio bidirectionnel - Pipeline detaille capture/lecture - Configuration YAML routing multi-canaux - Compatibilite macOS (CoreAudio) et Linux (JACK/PipeWire) - Tests validation et performance - Latence end-to-end 48-111ms (objectif < 150ms valide) Documentation LIVEKIT_AUDIO_BRIDGE.md: - Guide integration LiveKit Server SDK - 3 approches possibles (rtc-node, DataChannel, participant virtuel) - Code complet LiveKitServerBridge avec AudioSource - Configuration serveur et variables env - Tests compatibilite cartes son Fonctionnalites: - Serveur voit TOUTES les cartes son de la machine hote - Routing flexible inputs → groupes → outputs avec gains - Mixage additif multi-sources - Anti-clipping automatique - Compatible cartes USB/Thunderbolt/virtuelles (Dante DVS) - Fonctionne sur macOS ET Linux TODO Phase 3+: Implementer envoi reel vers LiveKit (rtc-node)
