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 dependencies²
  • Run the example file

• Generate video for a specific loudspeaker arrangement

• Combine the data with the Audiovisual Speech Corpus³ to generate synthetic multi-talker scenes. Note that the link on the original publication is no longer available. A mirror source is provided in⁴
