Conan Voice on TeamSpeak 3 SDK (ClientLib + ServerLib) — Development-Ready Plan

New product, new branch ts3-Testing. The V8 retail plugin on tsmain stays intact and is reused for logic only.

Items marked [VERIFY] are exact names/signatures to confirm against serverlib.h / clientlib.h and the bundled API reference during Phase 0. Everything unmarked is confirmed from TeamSpeak docs/examples.

0. The two SDKs (why this is a real switch, not a rename)

Client Plugin SDK (today, V8) TeamSpeak 3 SDK (this plan)
Header(s) ts3_functions.h (TS3Functions) clientlib.h + serverlib.h
Function family ts3plugin_* callbacks ts3client_* and ts3server_*
Who hosts voice retail ts3server our conan-voice-server process
Who runs the client retail TeamSpeak app loads our DLL our app embeds ClientLib
Can decide who hears whom no (edit local PCM only) yes (ts3server_setClientWhisperList)
License free paid; free evaluation for dev
Interop plugin only talks to retail TS SDK client only talks to SDK server (0x0705 otherwise)

Proof today is Plugin SDK: sdk/README.md line 1 = "TeamSpeak 3 Client Plugin SDK"; repo has ts3plugin_*, no ts3client_*/ts3server_*.

Consequence: the "Conan Voice Client" is a standalone ClientLib app (users run it like the Mumble client), not retail TeamSpeak + plugin.

2. Server process — exact lifecycle

File: server/src/main.c (+ server/src/ts_server_adapter.c).

Startup order (each step checks the return code with ts3server_getGlobalErrorMessage on failure):

1. load config (server/config/*.ini)          -> our Config module
2. start logger                                -> our Logging module
3. fill ServerLibFunctions (memset 0, assign callbacks)
4. ts3server_initServerLib(&funcs, LogType_FILE|LogType_CONSOLE, logDir)
5. ts3server_createServerKeyPair(...) OR load stored keypair   [VERIFY exact name]
6. ts3server_createVirtualServer(port, "0.0.0.0", name, keyPair, maxClients, &serverID)
7. init Voice backend (PlayerManager, ProximityEngine, VoiceRouter)
8. run event loop (routing tick; SDK callbacks fire on SDK threads)
9. shutdown: ts3server_stopVirtualServer(serverID)
             ts3server_destroyServerLib()

Confirmed signatures:

  • unsigned int ts3server_initServerLib(const struct ServerLibFunctions* funcs, int usedLogTypes, const char* logFileFolder);
  • unsigned int ts3server_createVirtualServer(unsigned int serverPort, const char* serverIp, const char* serverName, const char* serverKeyPair, unsigned int serverMaxClients, uint64* result);
  • unsigned int ts3server_stopVirtualServer(uint64 serverID);
  • unsigned int ts3server_destroyServerLib(void);
  • Routing: unsigned int ts3server_setClientWhisperList(uint64 serverID, anyID clientID, const uint64* channelIDs, const anyID* clientIDs);
  • Enumerate: ts3server_getClientList(serverID, anyID** result), ts3server_getChannelList(serverID, uint64** result), free with ts3server_freeMemory(ptr).

Callbacks we register in ServerLibFunctions (assign only what we use):

  • onClientConnected(serverID, clientID, channelID, ...) [VERIFY arg list] -> PlayerManager.add
  • onClientDisconnected(serverID, clientID, channelID, ...) -> PlayerManager.remove + clear whisper list
  • onClientMoved(serverID, clientID, oldCh, newCh, ...)
  • onServerTextMessageEvent / onChannelTextMessageEvent -> fallback game-data channel (see 5)
  • onClientStartTalkingEvent / onClientStopTalkingEvent -> HUD "who speaks" hints
  • onUserLoggingMessageEvent -> our logger
  • onAccountingErrorEvent -> license/slot errors (must handle for eval license)

3. Client app — exact lifecycle

File: client/src/main.c (+ client/src/ts_client_adapter.c, client/src/game_provider_*.c).

1. fill ClientUIFunctions (callbacks) 
2. ts3client_initClientLib(&clientFuncs, NULL, LogType_FILE, NULL, resourcesPath)  [VERIFY arg list]
3. ts3client_spawnNewServerConnectionHandler(0, &scHandlerID)
4. identity: load stored, else ts3client_createIdentity(&id) then persist
5. ts3client_openPlaybackDevice(scHandlerID, "", "")   // default device
   ts3client_openCaptureDevice(scHandlerID, "", "")
6. ts3client_startConnection(scHandlerID, identity, host, port,
                             nickname, NULL/*default channel*/, "", serverPassword)
7. wait for onConnectStatusChangeEvent == STATUS_CONNECTION_ESTABLISHED
8. loop: push game data (see 5), set 3D (see 6), render HUD
9. shutdown: ts3client_stopConnection(scHandlerID, "leaving")
             ts3client_destroyServerConnectionHandler(scHandlerID)
             ts3client_destroyClientLib()

Confirmed:

  • ts3client_startConnection(scHandlerID, identity, ip, port, nickname, defaultChannelArray, defaultChannelPassword, serverPassword)
  • ts3client_stopConnection(scHandlerID, quitMessage)
  • ts3client_getConnectionStatus(scHandlerID, int* result)
  • Callback onConnectStatusChangeEvent(scHandlerID, newStatus, errorNumber); onServerStopEvent(scHandlerID, shutdownMessage).

ClientLib callbacks we implement: onConnectStatusChangeEvent, onNewChannelEvent, onClientMoveEvent, onTalkStatusChangeEvent, onServerStopEvent, onEditPlaybackVoiceDataEvent (local audio effects: reverb/lowpass reuse from V8), onCustom3dRolloffCalculationClientEvent (custom distance curve). [VERIFY exact callback names in clientlib.h]

4. Data flow: connect -> position -> routing -> voice

sequenceDiagram
  participant G as Conan (game)
  participant C as Client app (ClientLib)
  participant S as Server (ServerLib)
  participant R as VoiceRouter

  C->>S: ts3client_startConnection
  S-->>C: onConnectStatusChangeEvent(ESTABLISHED)
  S->>S: onClientConnected -> PlayerManager.add(clientID)

  loop ~20 Hz
    G->>C: IGameDataProvider.getPlayerState(pos,rot,ids)
    C->>C: ts3client_setClientSelfVariableAsString(CLIENT_META_DATA, packed)
    C->>S: ts3client_flushClientSelfUpdates
    S->>S: metadata change -> PlayerManager.updatePos(clientID,pos)
  end

  loop ~5-10 Hz (routing tick)
    R->>R: spatial hash -> audible set per client
    R->>S: ts3server_setClientWhisperList(serverID, A, {}, {B,C})
    R->>S: ts3server_setClientWhisperList(serverID, D, {}, {})  // hears no one
  end

  Note over C,S: A speaks -> ClientLib routes A's voice only to B,C (whisper list)
  S-->>C: voice packets to B,C only
  C->>C: onEditPlaybackVoiceDataEvent -> distance gain/pan/reverb
  C->>C: 3D attributes -> spatialization

Whisper-list routing detail (from TeamSpeak Whisper Lists example): a client with a whisper list bypasses normal channel voice and sends only to the listed clients/channels. So the router expresses the full audible matrix as per-speaker client-ID lists. Clearing = ts3server_setClientWhisperList(serverID, client, NULL, NULL).

Caveat to design around: while a client has an active whisper list, its normal channel talk is disabled. Therefore ALL proximity/radio/whisper voice must be expressed through whisper lists (do not mix with channel voice for routed players).

5. Game-data transport (the previously-missing piece)

Requirement: client must tell the server its position ~20 Hz without an external HTTP/REST/WebSocket API (user constraint). Two in-SDK mechanisms:

  • Primary: CLIENT_META_DATA (string, up to 4096 bytes, Read/Write).
    • Client: ts3client_setClientSelfVariableAsString(scHandlerID, CLIENT_META_DATA, packedState) then ts3client_flushClientSelfUpdates(scHandlerID, NULL).
    • Server: read with ts3server_getClientVariableAsString(serverID, clientID, CLIENT_META_DATA, &out) [VERIFY server-side getter + whether a change event fires; if no push event, poll on the routing tick].
    • Payload = compact base64/binary: playerId,charId,x,y,z,yaw,voiceMode,flags,seq (reuse V8 CEPOS packing idea, rewritten).
  • Fallback: text messages TextMessageTarget_SERVER -> server onServerTextMessageEvent. Heavier; use only for discrete events (RADIO_JOIN, WHISPER_START) if metadata proves too slow.

Small control protocol (carried over the chosen mechanism): HELLO, AUTH, AUTH_RESULT, POSITION, VOICE_STATE, RADIO_JOIN/LEAVE, WHISPER_START/STOP, CONFIG, PING/PONG (from v2 draft, kept).

6. 3D voice

Server feeds authoritative positions; client applies 3D locally via ClientLib 3D API [VERIFY exact names]:

  • Listener (self): ts3client_systemset3DListenerAttributes(scHandlerID, &posSelf, &forward, &up)
  • Per remote speaker: ts3client_channelset3DAttributes(scHandlerID, remoteClientID, &posRemote) (or ts3client_set3DWaveAttributes)
  • Custom rolloff: implement onCustom3dRolloffCalculationClientEvent to match Conan voice ranges.
  • Vectors use TS3_VECTOR {float x,y,z}.

We do NOT build a voice engine; TeamSpeak does encode/decode/transport/spatialize.

7. Module map (server + client) with the APIs each owns

Server (server/src/):

  • ts_server_adapter — the ONLY file calling ts3server_*. Exposes ITeamSpeakServer (connectClient/disconnect/getClientState/setWhisperList/getClientMeta/moveClient).
  • player_manager — VoicePlayer{tsClientId, conanPlayerId, characterId, pos, voiceMode, authenticated}; add/remove on connect/disconnect; updatePos from metadata.
  • proximity_engine — spatial grid (cells), neighbor query, distance -> audible; reuse V8 proximity_math/zone_resolve logic (rewrite).
  • voice_router — merges proximity + radio + whisper + global + permissions -> per-client target list -> ITeamSpeakServer.setWhisperList; routing cache + hysteresis.
  • auth — SDK identity -> Conan player mapping via short-lived token.
  • radio_manager, whisper_manager, permissions — logical groups.
  • config, logging.

Client (client/src/):

  • ts_client_adapter — the ONLY file calling ts3client_*. Exposes ITeamSpeakClient.
  • game_provider — implements IGameDataProvider (file/IPC, ported from Mumble/V8 pos_file).
  • voice_client_state, audio_effects (reuse V8 reverb/lowpass in onEditPlaybackVoiceDataEvent), hud, config, logging.

Shared (shared/): protocol/ (message + meta-data packing), types/ (Vector3, PlayerId, VoiceMode), config/.

8. Threading model

  • SDK callback threads: ts3server_* / ts3client_* callbacks fire on SDK-owned threads. Keep them short; hand off to our queues. (Same discipline as V8's callback-thread rule, but now applied to SDK callbacks.)
  • Routing tick thread (server): 5-10 Hz; reads player snapshots, computes audible sets, calls setClientWhisperList. Never blocks on game I/O.
  • Game provider thread (client): ~20-30 Hz reads Conan position; publishes snapshot; the flush to metadata happens on a controlled cadence.
  • Audio (client): onEditPlaybackVoiceDataEvent — no locks, snapshot read only (reuse V8 PCM ownership pattern).

9. Repository layout (branch ts3-Testing)

conan-voice/
├── client/  { src/ include/ CMakeLists.txt }
├── server/  { src/ include/ config/ CMakeLists.txt }
├── shared/  { protocol/ types/ config/ }
├── sdk/     { include/ lib/ bin/ examples/ }   # examples untouched
├── tests/   { unit/ integration/ load/ }
├── docs/
└── CMakeLists.txt   # SDK path configurable, no C:\Users\... hardcodes

Kept isolated from src/ so the V8 DLL build is never disturbed and tsmain merges stay clean.

10. Phases (with concrete API deliverables)

Phase 0 — SDK + license + API verification. Get SDK (ClientLib+ServerLib) + evaluation license; build official ServerLib + ClientLib examples; confirm every [VERIFY] name against serverlib.h/clientlib.h. Exit: examples run; API list frozen.

Phase 1 — server bootstrap (Milestone 1). main.c runs steps 1-9 of section 2; start/stop/restart clean. No Conan, no routing.

Phase 2 — client PoC + metadata. ClientLib app connects (section 3); publishes CLIENT_META_DATA; server reads it. Two clients talk in one channel.

Phase 3 — routing PoC (make-or-break). voice_router sets whisper lists: A -> {B} only; then chained A->B, B->C, C-/->A. Proves server-authoritative "who hears whom".

Phase 4 — Conan integration. IGameDataProvider feeds real position/rotation/ids/voice-state (ported from Mumble/V8).

Phase 5 — proximity + 3D. spatial grid, cache, hysteresis in proximity_engine; 3D via section 6.

Phase 6 — features. radio, whisper groups, global, cave reverb (server env state -> client effect), HUD, voice modes, root-channel config.

Phase 7 — performance. 10/25/50/100/250 clients; CPU, RAM, network, routing latency, voice latency, reconnects.

Phase 8 — production. Linux/systemd, auto-restart, logging, monitoring, config validation, crash recovery, security review, commercial license finalized.

11. Definition of done

  • Milestone 1: ServerLib up, virtual server created, SDK client connects, two clients pass voice, server changes whisper routing, clean shutdown + restart.
  • v0.1: Conan position -> proximity voice -> 3D voice; player mapping; voice range; reconnect; basic HUD.
  • v0.2: radio, whisper, global, root-channel config, cave reverb, HUD colors, permissions.
  • v1.0: production server+client, 250+ tested, perf documented, monitoring, crash recovery, security review, license cleared, full docs.

12. Hard gates / risks

  • License: paid, negotiated; evaluation only for dev. (licensing)
  • EOL: TS3 + TS3 SDK end 2027-12-31 — keep IVoiceTransport/ITeamSpeakServer seams so transport can be swapped; do not leak SDK calls outside the two adapter files.
  • API-name risk: some 3D/keypair/metadata-getter names are [VERIFY] until Phase 0.
  • Whisper-only routing: routed clients lose normal channel voice — design accepts this.
  • Position trust: v1 client-reported (spoofable); v2 game-server-fed.

13. Open questions (resolved in Phase 0/PoC)

  1. Exact ServerLibFunctions / ClientUIFunctions callback sets and arg lists.
  2. Server-side getter + change event for CLIENT_META_DATA (push vs poll).
  3. Exact 3D + keypair function signatures.
  4. Whisper-list update rate that stays artifact-free at 5-10 Hz.
  5. Real client cap under the negotiated license.
  6. Position authority (client vs game server) and id binding (Conan/Steam/SDK identity).
  7. EOL-2027 successor/exit path.
