To test your BVCTelephony setup and address echo and background noise issues, follow these steps: 1. Enable BVCTelephony Model: Use the

BVCTelephony

model in your

RoomInputOptions

for optimal telephony performance. This model is designed to handle background voice and noise cancellation effectively. Example:

room_input_options=RoomInputOptions(
    noise_cancellation=noise_cancellation.BVCTelephony(),
)

1. Test in Different Environments: Capture audio in various settings (e.g., quiet rooms, noisy environments) to assess the model's performance. 2. Compare Audio Quality: Play audio samples to evaluate the effectiveness of the BVCTelephony model. 3. Monitor Audio in Real-Time: Use tools or logs to check audio quality during calls and ensure noise cancellation is functioning as expected. 4. Troubleshoot Echo Issues: ◦ Ensure microphone and speaker placement is correct or use a headset to avoid hardware-induced echo. ◦ Adjust echo cancellation settings using the

AudioProcessingModule

class. 1. Client-Side Noise Cancellation: Disable client-side noise cancellation if using server-side noise cancellation to avoid interference. 2. Log and Debug: Check logs for errors or warnings related to noise cancellation and use LiveKit debugging tools to identify issues. These steps should help you test and optimize your setup effectively. Let me know if you need further assistance!
