# Evaluation Data for Device 3

## 1. Introduction

This contribution provides the recording database for **Device 3**, captured according to the evaluation recording scenarios defined in DaCAS-2 [1], specifically under **Scenario 3** [2].

## 2. Recording Setup and Database Specifications

### 2.1 Physical Setup

The recordings were conducted in an **anechoic chamber** with the following configuration:

- **Device placement**: Center of anechoic chamber on a turntable
- **Device orientation**: Landscape orientation
- **Source distance**: d_UE = 1m
- **Height**: H = 1.3m (both UE and sound source)
- **Speaker**: GENELEC 8351

### 2.2 Recording Parameters

The database specifications are detailed in Table 1:

| Parameter | Specification |
|-----------|---------------|
| **Target device** | Device type 3 |
| **Recording scenario** | Scenario 3 |
| **File naming convention** | D03_S03_[Orientation]_[ele]deg_[azi].wav<br>Example: D03_S03_Landscape_000deg_000deg.wav |
| **Sample rate** | 48 kHz |
| **Bit depth** | 16-bit |
| **Audio format** | .wav |
| **Recording duration** | 35.4s per file |
| **Number of channels** | 4 channels (ch1=mic1, ch2=mic2, ch3=mic3, ch4=mic4) |

### 2.3 Recording Angles

The recordings cover the following angular positions:

- **Azimuth**: 0° to 360° in 15° increments [0°:15°:360°)
- **Elevation**: 0°

## 3. Conclusion

The draft database for Device Type 3 is submitted for review. The current submission includes recordings in **landscape orientation only**. The remaining recordings, including **table-mounted and portrait orientations**, will be proposed based on meeting agreements. The completed version will be processed for future updates to **DaCAS-1**.
