Guidance Needed: Tuning XVF3800 for Hospital Room (Shared Space) Patient–Nurse Communication Hardware

[Prasaanth]

Hello XMOS Community,

I’m currently developing a hardware solution for nurse–patient communication in hospital rooms (~15x15 ft), similar in concept to a conference room audio system. The goal is to enable clear, hands-free, two-way audio where the nurse can hear the patient clearly—without ambient noise, room echo, or muffling.

After some research, I selected the **XVF3800** as the core audio processor since it provides the essential features like **AEC, beamforming, noise suppression, and voice activity detection**.

I’ve validated the **default reference binary**, but the performance doesn’t meet the needs for a shared-space environment. Later, I learned that the default binary is tuned for *personal space* use cases (e.g., smart speakers or near-field). I understand that **it’s our responsibility to tune the XVF3800 firmware** according to the specific room acoustics, microphone/speaker configuration, and mechanical design, and that there’s no general-purpose binary available for this.

I’ve reviewed the datasheet, user manual, and tuning guide and have a fair conceptual understanding of the processing chain and tunable parameters. However, since I’m relatively new to audio DSP and acoustic tuning, I’m not sure about the **standard steps, recommended tools, and best practices** to follow when tuning the XVF3800 for a room-scale environment like this.

Could anyone please guide me on:

1. The **recommended workflow or tuning process** for adapting the XVF3800 to a shared-space (conference room–like) scenario.
2. The **measurement tools/software** typically used to evaluate and tune beamforming, AEC, and noise suppression performance.
3. Any **reference designs, application notes, or example binaries** closer to a far-field or shared-space configuration.
4. Tips or lessons learned from others who have deployed XVF3800 (or similar XMOS parts) in larger room environments.

Any guidance or resources would be extremely helpful — even a high-level workflow would give me the right direction.

Thank you in advance for your time and expertise.

Best regards,
Prasaanth
