Subject: [PATCH 1/7] fix: shutdown propre sans erreurs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Problèmes corrigés pendant l'arrêt serveur :
1. RangeError offset bounds : vérification availableSpace avant .set()
2. audioBackend null : vérification avant queueAudio()
3. LiveKit track not found : try/catch sur unpublishTrack

Shutdown maintenant sans erreurs fatales.

Subject: [PATCH 2/7] fix: persistance des groupes avec ConfigManager
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Conversion des routes groupes (GET/POST/PUT/DELETE) pour utiliser configManager
- Suppression de loadConfig() et saveConfig() locales (redondantes)
- Fix: les modifications de groupes sont maintenant persistées correctement
- Les groupes créés/modifiés/supprimés survivent au redémarrage du serveur

Subject: [PATCH 4/7] fix: routing audio macOS avec support multi-canaux et
 LiveKit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Corrections majeures pour le support audio sous macOS :

- CoreAudioBackend : syntaxe sox correcte avec `-t coreaudio "Device Name"`
- AudioBridge : dé-entrelacement stéréo → canaux séparés (ligne 410-424)
- AudioBridge : entrelacement canaux → stéréo pour sortie (ligne 490-522)
- AudioBridge : duplication mono → stéréo pour LiveKit (ligne 438-449)
- config.yaml : ajout `channels: 2` pour capture stéréo
- config.yaml : ajout groupes "Production" et "Technique"

Résultat :
- Capture stéréo fonctionnelle depuis Loopback Audio 4
- Routing : 2 inputs → 3 groupes → LiveKit + 2 outputs
- Format audio correct pour LiveKit (mono dupliqué en stéréo)
- Pas d'erreur "Taille frame incorrecte"

Problème restant : sox playback se ferme après 0.4s (EPIPE)

From 9aff58c5288a95e7df3192937dbaa9d2b2d54115 Mon Sep 17 00:00:00 2001
From: Benoit <benoit.91800@hotmail.fr>
Date: Tue, 2 Jun 2026 00:45:41 +0200
Subject: [PATCH 5/7] =?UTF-8?q?fix:=20d=C3=A9formation=20audio=20par=20sat?=
 =?UTF-8?q?uration=20du=20mixage?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Problème:
- Son complètement déformé (clipping massif)
- CoreAudio capture en 32-bit mais traité comme 16-bit
- Mixage additif sans normalisation

Solution:
1. Sox convertit 32→16 bit automatiquement
2. GroupAudioRouter divise gain par nombre de sources
   Exemple: 2 inputs → groupe default = gain × 0.5 chacun

Résultat: Aucun clipping détecté, audio propre

- Ajout buffer d'accumulation dans CoreAudioBackend pour garantir frames fixes
- sox envoie des chunks de taille variable → accumuler jusqu'à frameSize complet
- Émission de frames exactement 960 samples × 2ch × 2 bytes = 3840 bytes
- Adaptation automatique mono/stéréo selon config channels
- Audio fluide sans hachage/robotique vers clients LiveKit

From 060453fe0689e9e5defe0d94ecff26196e1d734d Mon Sep 17 00:00:00 2001

Subject: [PATCH 7/7] fix: application du buffer d'accumulation aux backends
 Linux (PipeWire/JACK)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Ajout buffer d'accumulation dans PipeWireBackend (même pattern que CoreAudio)
- Ajout buffer d'accumulation dans JACKBackend
- pw-cat et jack_rec émettent aussi des chunks de taille variable
- Garantit frames fixes (960 samples) sur tous les backends
- Prévient audio haché/robotique sous Linux
