- All SDK methods are thread-safe. You may call them from multiple threads simultaneously.
- Callbacks (`onState`, `onTranscript`) run on background threads managed by the SDK. Keep them fast, non-blocking, and synchronised — use `std::atomic` or `std::mutex` for any shared state they touch.
- `ProcessSamples` blocks for one frame while the SDK reads processed audio from its internal buffer. Call it from your audio thread, not from inside a callback.
- Keep the `shared_ptr<IAudioProcessor>` alive for as long as you use the processor. Call `DestroyAudioProcessor` when done, then `Shutdown` last.

Never call `DestroyAudioProcessor` or `Shutdown` from inside an `onState` or `onTranscript` callback. Doing so causes a deadlock.
