livekit-plugins-murf-bvc
Murf background voice cancellation for LiveKit Agents: keeps the participant who is talking to the agent and removes other voices and noise before VAD, turn detection and STT. Runs on CPU in the agent process.
from livekit.agents import room_io
from livekit.plugins import murf_bvc
await session.start(
room=ctx.room,
agent=agent,
room_options=room_io.RoomOptions(
audio_input=room_io.AudioInputOptions(noise_cancellation=murf_bvc.BVC()),
),
)
BVC() registers a native LiveKit audio filter (like livekit-plugins-noise-cancellation), so frames
are processed inside LiveKit's core without crossing into Python, and one value serves every
participant. On livekit versions without audio-filter plugins, or with native=False, it returns a
BVCProcessor instead; that processes one track, so pass a selector for multi-participant rooms:
noise_cancellation=lambda params: murf_bvc.BVC(native=False).
License
Pass the Murf license token as BVC(license_key=...) or set MURF_BVC_LICENSE. It is checked
offline (signature and expiry). Without a valid license the filter logs an error and passes audio
through unprocessed, delayed by the filter latency (10 ms at 16 kHz, about 13.6 ms at 24/48 kHz).
Options
restore=True: mixes back what was removed while only the caller is talking (speaker check every 0.5 s).normalize=True: brings the caller to a fixed level before the model.models_dir: override the bundled models.
Wheels: manylinux_2_28 x86_64 (x86-64-v3) and aarch64 (Graviton2+), macOS 11+ arm64 and
10.15+ x86_64. No ONNX Runtime or other native dependencies.
