BTDEI HpIR Database: officially in the main SOFA repository

Kemar_akg240 We are proud to announce the inclusion of the BT-DEI HpIR database also in the official SOFA repository, an ever-growing collection of HRTFs, BRIRs, and HpTFs from many research institutions worldwide.

At this link, all BT-DEI HpIRs have been stored and ready to be downloaded in the latest SimpleHeadphoneIR SOFA convention. Accordingly, the “BT-DEI – HpIR Database” webpage has been updated.


“New: Headphone IRs (HpIRs) for over 100 human listeners (ARI and BT-DEI databases)”

For those of you interested in HRTFs, BRIRs, DRIRs, etc.: have a look at the full list of available SOFA datasets!



BTDEI HpIR Database is now on-line for the AES Los Angeles 2014

AES137-600x360The 137th Audio Engineering Society Convention is approaching and a piece of PADVA is flying to Los Angeles with the paper “PHOnA: A Public Dataset of Measured Headphone Transfer Functions” by Braxton Boren, Michele Geronazzo, Piotr Majdak, and Edgar Choueiri. Check the PADVA’s publication page.


SOFA SingleHeadphoneIR-0.1On the occasion of this event, the PADVA project makes publicly available and hosts the BT-DEI HpIR Database which is a database of Headphones Impulse Response (HpIR) measurements for 3 different headphones and up to 24 different subjects, including the KEMAR mannequin with and without large pinnae.

The database includes 10 measurements of headphone impulse responses for each headphones and subject. These measurements were recorded at the entrance of open and blocked ear canal, OEC and BEC respectively, with Soundman OKMII Classic in-ear microphones. All the measurements are stored in bt-dei format v. 0.2 (a Matlab based data format).


Finally, we are proud to announce that the BT-DEI HpIR Database has been part of the PHOnA dataset (Princeton Headphone Open Archive) since July 2014, with the purpose of making the large amounts of existing HpTF data publicly available to researchers worldwide. All measurements are stored in SOFA data format (SimpleHeadphoneIR convention) thanks to the SOFA project and Michele’s contribution for headphone support.
