Welcome to the SONICOM Ecosystem

A repository dedicated to spatial hearing and binaural audio!

The SONICOM Ecosystem provides an interactive repository for spatial auditory data closely integrated with tools for binaural rendering and auditory modeling. Its content is open access and can be cited via persistent URLs and DOIs. It also provides a programmatic interface for downloading data subsets, reinforcing the idea of reproducible research. Its commenting functionality enables researchers and end users to provide feedback easily. The connection of databases with tools and external resources renders it a true Ecosystem for the spatial-hearing community. More information...


A database is a collection of data stored in a structured way. A database consists of datasets, all of which have the same structure specified by the dataset definition. Tools are files which do not need the structure of a database. They can be of the category software, model, text, physical object, or something else.
Latest database: Bahu Normalization (2004-2025) Latest tool: GAN-based HRTF upsampling (2024)
