Implements camb.realtime, a new module that wraps the /v1/realtime WebSocket endpoint. Mirrors the live_transcription module's session, event dispatch, and transport patterns. Key behaviours: - connect() opens the WS, sends session.update with auth and config, and returns immediately; callers register handlers then await session.wait_until_ready() (90 s timeout) for session.created - Binary frames and JSON response.audio.delta both dispatch to AudioDeltaEvent with uniform data: bytes — handlers see no difference - session.starting is a supported event so callers can show a loading indicator during the 30+ s cold-boot of non-iris models - stream_audio() accepts any AsyncIterable[bytes], making it compatible with live_transcription.Microphone and FileAudioSource Wires client.realtime property onto both CambAI and AsyncCambAI.
Two runnable examples for the new camb.realtime module: - realtime_translation_microphone.py: mic in (24kHz PCM16) -> plays translated audio out via sounddevice, prints translated text. - realtime_translation_file.py: streams a 24kHz mono WAV -> writes the translated audio to an output WAV (headless-testable). Both use model="iris": in live testing against realtime.camb.ai it was the only model that returned translated audio (lilac/orchid connected but emitted nothing; violet never reached session.created). Audio is PCM16 mono 24kHz in both directions. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
examples: realtime speech-to-speech translation (mic + file)
