TeleQuick Core (C++ FFI)

The C++23 core that backs every language SDK in the TeleQuick family. Exposes a stable C ABI (ffi_bridge.cc) and a WebAssembly build (apm_wasm.cc) so language wrappers — Python, TypeScript, Go, Rust, Java, .NET — share one serde, one APM (audio processing), and one media pipeline.

What lives here

• serde_lite.h / serde_test.cc — zero-allocation wire codec used by every SDK.
• apm_pipeline.{hh,cc} — audio processing chain (resample / VAD / denoise hooks).
• ffi_bridge.cc — C ABI exported as libtelequick_core_ffi.so (and .dll / .dylib).
• apm_wasm.cc / wasm_bridge.cc — WASM build for typescript-sdk browser usage.
• apm_ffi.cc — FFI binding for the audio processing module.
• g711_lite.h — PCMU/PCMA codec helpers.

Build

The canonical build is via Bazel from the TeleQuick workspace; the BUILD.bazel target is :telequick_core_ffi (shared library) and :telequick_core_wasm (emscripten WASM module).

bazel build //:telequick_core_ffi
bazel build //:telequick_core_wasm --config=wasm

The resulting artefacts are consumed at runtime by the per-language SDKs — typically via TELEQUICK_LIB_PATH (native) or the bundled .wasm (browser).

Versioning

Method IDs are mirrored across every language SDK. See serde_lite.h and the generated method_id.* files in each language repo.
