# Enhanced Noise Cancellation Plugin for LiveKit

Add realtime enhanced noise cancellation to inbound `AudioStream`. Fully compatible with [LiveKit Agents](https://github.com/livekit/agents).

Requires [LiveKit Cloud](https://cloud.livekit.io).

[Read more in the documentation](https://docs.livekit.io/home/client/tracks/noise-cancellation/)

## Usage

### In LiveKit Agents

Include the filter in `RoomInputOptions` when starting your `AgentSession`:

```python
from livekit.plugins import noise_cancellation

# ...
await session.start(
    # ...,
    room_input_options=room_io.RoomInputOptions(
        noise_cancellation=noise_cancellation.BVC(),
    ),
)
# ...
```

### On AudioStream

Noise cancellation can also be applied to any individual inbound `AudioStream`:

```python
stream = rtc.AudioStream.from_track(
    track=track,
    noise_cancellation=noise_cancellation.NC(),
)
```

## Available Models

- `noise_cancellation.NC()`
- `noise_cancellation.BVC()`
- `noise_cancellation.BVCTelephony()`

## Notes

Noise cancellation only needs to be applied once, so if you choose to apply it here you should disable noise cancellation / Krisp filter in your frontend clients.

If you experience crashes when using `noise_cancellation` (especially on AMD CPUs), it may be due to a failure in OpenBLAS's CPU detection. Manually setting the `OPENBLAS_CORETYPE` environment variable to a more conservative value (e.g., `Haswell`) may resolve the issue.
