# R3VIVAL - Repository of Room Responses and 360 Videos of a Variable Acoustics Lab

## SUMMARY OF THE DATA 
This datset contains Spatial Room Impulse Responses (SRIR) and 360 stereoscopic video recordings of a variable acoustics lab. The dataset contains:
- Spatial Room Impulse Responses (total of 272 SRIRs).
  - 30 source positions arranged in 3 concentric circles (1.5m, 2m, 3m) every 30 degrees. 
    - The largest circle contains only 6 positions due to room dimensions.
    - Directional sound source (Genelec 8320).
  - 4 source positions next to room corners.
    - Omnidirectional source (B&K 4295).
  - 1 receiver position (7 microphone open array from [^1]).
  - 8 acoustic panel configuration.
    - 5 uniform conditions (0%, 25%, 50%, 75%, 100% absorption).
    - 3 asymmetric configurations (right, right/back, right/back/left absorptive).
    
- Video captures
  - Stereoscopic 360 videos (resolution 4096 x 2160).
  - Captured with LivePlanetVR camera.
  - 2 rooms (Lab and RoomA - shoebox room).
  - 4 seconds duration.
  - Static scenes showing the empty room.

## How to use this data? (Work in Progress)

- Render Binaural Room Impulse Responses
  - Set up the Binaural SDM Toolbox and its dependencies[^2] 
  - Run the example file

- Generate video for a specific loudspeaker arrangement

- Combine the data with the Audiovisual Speech Corpus[^3] to generate synthetic multi-talker scenes. Note that the link on the original publication is no longer available. A mirror source is provided in[^4]
