conferences – IT'S A DIVE

IT’S A DIVE @ I3DA 2021

September 10, 2021September 10, 2021ssp@create.aau.dk

On Wednesday, September 8th, our student Jonas Siim Andersen presented the final paper from IT’S A DIVE, “Evaluation of individualized HRTFs in a 3D shooter game” (J.S. Andersen, R. Miccini, S. Serafin, S. Spagnol), at the 1st International Conference on Immersive and 3D Audio. The conference has been an entirely virtual event, with about 120 registered participants attending the presentation. The conference proceedings will be submitted by the organizers to the IEEE Xplore Digital Library. In the meantime, you can watch Jonas’ recorded presentation here.

IT’S A DIVE @ IEEE VR 2021

March 29, 2021March 29, 2021ssp@create.aau.dk

Last Saturday, Riccardo presented the paper “A hybrid approach to structural modeling of individualized HRTFs” (R. Miccini, S. Spagnol) at the IEEE 6th VR Workshop on Sonic Interactions in Virtual Environments, as part of the 28th IEEE Conference on Virtual Reality and 3D User Interfaces (IEEE VR 2021). Like last year the conference has been an entirely virtual event, and the workshop was live-streamed for free. About 80 participants attended the workshop. You can watch the recorded presentation here (starting at 01:58:43) and download the final version of the paper here.

The paper presents a hybrid approach to individualized head-related transfer function (HRTF) modeling which requires only 3 anthropometric measurements and an image of the pinna. A prediction algorithm based on variational autoencoders synthesizes a pinna-related response from the image, which is used to filter a measured head-and-torso response. The interaural time difference is then manipulated to match that of the HUTUBS dataset subject minimizing the predicted localization error. The results are evaluated using spectral distortion and an auditory localization model. While the latter is inconclusive regarding the efficacy of the structural model, the former metric shows promising results with encoding HRTFs.

IT’S A DIVE @SMC2020

July 3, 2020ssp@create.aau.dk

On June 24, 2020, our student Marius George Onofrei presented the paper “3D ear shape as an estimator of HRTF notch frequency” at the 17th Sound and Music Computing Conference, annual forum of the international Sound and Music Computing Community. You can download the final proceedings version of the paper here.

The conference, organized by three institutions from Torino, Italy together with Aalborg University, has been an entirely free virtual event broadcasted on YouTube on June 24-26. Day 1 had a total number of over 1,500 views. You can watch all the conference sessions on demand on the SMC 2020 YouTube channel.

IT’S A DIVE @ICASSP2020

May 15, 2020ssp@create.aau.dk

Last week Simone presented his paper “Auditory model based subsetting of head-related transfer function datasets ” at the 45th IEEE International Conference on Acoustics, Speech, and Signal Processing (IEEE ICASSP 2020) . The conference has been an entirely free virtual event, with an exceptional number of more than 14,000 participants attending the technical content. You can watch again the presentation and access the paper here (until June 8, 2020).

IT’S A DIVE @IEEEVR

March 26, 2020ssp@create.aau.dk

Last Sunday, we presented the paper “HRTF individualization using deep learning” (R. Miccini, S. Spagnol) at the IEEE 5th VR Workshop on Sonic Interactions in Virtual Environments, as part of the 27th IEEE Conference on Virtual Reality and 3D User Interfaces (IEEE VR 2020). Due to the pandemic outbreak, the conference has been an entirely virtual event, and the workshop was live-streamed for free. You can watch the recorded presentation here (starting at 01:46:30) and download the final version of the paper here.

IT’S A DIVE @UniMI + @NordicSMC

November 21, 2019ssp@create.aau.dk

Over the past week, the project was present at two events – first, within a seminar targeted at Master students and researchers in computer science at the University of Milano, Italy, where Simone presented an overview of the project contents and goals.

Then, our student Riccardo presented the paper Estimation of pinna notch frequency from anthropometry: an improved linear model based on Principal Component Analysis and feature selection (R. Miccini, S. Spagnol) at the 1st Nordic Sound and Music Computing Conference in Stockholm, Sweden. About 50 international researchers, mostly from Nordic European countries, attended the conference. You can download the final proceedings version of the paper here.

IT’S A DIVE @ SMC 2019

May 30, 2019May 30, 2019ssp@create.aau.dk

On May 29, 2019 we were in Málaga at the 16th Sound and Music Computing Conference, annual forum of the international Sound and Music Computing Community, to present the first project-funded work, The Viking HRTF dataset (S. Spagnol, K.B. Purkhús, S.K. Björnsson, R. Unnthórsson). You can download the final proceedings version of the corresponding article here.

The work we presented – in poster format – is about the collection and evaluation of the HRTF dataset described in our previous post. About 100 international researchers attended the conference.
