Subject: [AUDITORY] The Extended SONICOM HRTF Dataset and Spatial Audio Metrics Toolbox From: "Poole, Katarina" <katarina.poole@xxxxxxxx> Date: Thu, 10 Jul 2025 12:43:14 +0000--_000_LO0P265MB67119ACFE0EBD03817217DD6BD48ALO0P265MB6711GBRP_ Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Dear community, We are pleased to announce the release of The Extended SONICOM HRTF dataset= , a significant update to the original version first released in 2023. This= new release is designed to support researchers working on headphone-based = spatial audio, HRTF synthesis, and machine learning for personalised spatia= l audio. The dataset now includes: * Over 320 acoustically measured HRTFs, making it one of the largest publicly= available collections to date * 200 synthetic HRTFs generated using Mesh2HRTF, based on high-resolution, pr= e-processed 3D head and ear scans * Optimised 3D mesh files in multiple formats to enable rapid and iterative H= RTF synthesis and a better link between morphology and acoustic properties * Demographic metadata (age, sex, ethnicity) for a subset of participants to = aid in understanding dataset representation * A new Spatial Audio Metrics (SAM) Toolbox, a Python package under continual= development to provide easy analysis and visualisation of HRTFs More details of the extended dataset can be found here: https://www.axdesign.co.uk/tools-and-devices/sonicom-hrtf-dataset You can explore and download the dataset here: https://transfer.ic.ac.uk:9090/#/2022_SONICOM-HRTF-DATASET/ More details on the SAM Toolbox is available here: https://github.com/Katarina-Poole/Spatial-Audio-Metrics We hope this resource is valuable to the auditory community and we welcome = any feedback or questions.
