Outline

This paper presents DSpAST, a novel audio encoder for spatial audio inference using large-scale language models. Building on the existing SpatialAST, it learns the type, direction, and distance information of sound events in separate forms. This design allows for efficient processing of diverse spatial audio information with a single encoder, and is expected to yield improved performance compared to existing single-encoder approaches. DSpAST demonstrates performance improvements over SpatialAST with only 0.2% additional parameters. Experimental results using the SpatialSoundQA dataset and the BAT system demonstrate that DSpAST outperforms SpatialAST.

Takeaways, Limitations

Takeaways:
A novel method for effectively extracting diverse spatial audio information using a single encoder is presented.
Achieving performance improvements while minimizing parameter increases compared to existing SpatialAST.
Contributes to improving the performance of spatial audio inference systems
Limitations:
The proposed DSpAST performance improvement may be limited to the SpatialSoundQA dataset and the BAT system.
Generalization performance on other spatial audio datasets or inference systems requires further experimentation.
Lack of detailed description of DSpAST's design and learning process (additional information needed)
