Ambiscaper: A Tool for Automatic Generation and Annotation of Reverberant Ambisonics Sound Scenes

The spatial nature of Ambisonics audio recordings makes them specially interesting for source localization and source separation tasks. Although existing proposals have already shown promising results, there is a lack of annotated databases, required for algorithm design, training and evaluation in this particular scenario. In this paper we present AmbiScaper, a tool for the automatic generation and annotation of reverberant Ambisonics sound scenes, published under an Open Source license to facilitate research reproducibility. As a use case, a database of annotated audio scenes has been created and published, along with an analysis with state-of-the-art sound localization algorithms.
