All scenes are delivered as 4th order ambisonics audio in AmbiX format (25 channels, 48 kHz, 24-bit PCM) combined with 360-degree video in equirectangular projection (8K, 30 fps). These formats support integration into advanced audio test setups where spatial reproduction and consistent playback are required for evaluating product performance. We also offer objective sound-quality measurements for further evaluation.

HOA-SSR Sound Scene Library for HOA audio testing
Use a curated HOA audio sound scene library for product development, feature testing, research and innovation in audio technology.
Use the HOA-SSR Dataset: Sound Scene Library to bring realistic, real-life audio experiences into the sound lab. It is a comprehensive Higher-Order Ambisonics Sound Scene Repository made up of more than 150 state-of-the-art audiovisual scenes captured in real life for audio product development and feature testing.
Applications in product development and research
The dataset is part of a catalogue of services within sound quality. supports work on hearing assistive devices (OTC), hearing aids, telecom headsets, TWS earbuds and AI model training. It also supports research and innovation in audio technology, fostering advancements in audio quality technologies through a curated library of recorded sound scenes used to test product performance in different situations.
Challenges
When audio teams need real-life sound scenes for feature testing, limited recorded material restricts evaluation across different situations.
Limited recordings restrict feature testing
When real-life sound scenes are not available, teams have less material for feature testing in audio product development.
Narrow scene coverage limits evaluation
When a broad library of recorded scenes is missing, it becomes harder to test product performance in different situations.
Lack of recorded scenes constrains research work
When carefully recorded audiovisual scenes are not available, research, innovation and AI model training have less material for evaluation work.
Benefits
Use recorded sound scenes to support feature testing, product development and AI model training.
Test features with real-life sound scenes
The dataset provides recorded audiovisual scenes captured in real life, giving teams material for feature testing in audio product development where realistic sound scenes are needed.
Work from a curated collection of 150+ scenes
As a curated collection of more than 150 audiovisual scenes, the sound scene library gives teams recorded material that can be used in feature testing and product development.
Support research in audio technology
The dataset supports research and innovation in audio technology through recorded real-life scenes that can be used in evaluation work and AI model training activities.
