Mission confiée
Audio Augmented Reality (AAR) is receiving increasing interest in various application domains, such as artistic creation and cultural mediation, communication and information, and the entertainment industry. Embedding computer-generated or pre-recorded auditory content into a user's real acoustic environment creates an engaging and interactive experience that, for example, can BE applied to video games, museum guides or radio plays. A key challenge is to spatialize sounds in 3D in the user's headset in a way that is consistent with the current environment of the user. For instance, a sound source placed 2 meters away in an office environment should not BE rendered the same way as a source placed 10 meters away in a large museum hall. To achieve this, acoustical information about the user's environment is needed. A key task of the collaborative research project HAIKUS is to retrieve such information solely using microphones embedded in the user's headset.
In this context, this master internship will focus on developing machine learning methods that estimate the volume, reverberation time and/or absorption properties of a room based on multiple binaural recordings of a sound source from different user's positions. The problem of estimating the distance of the sound source will also BE considered.
Principales activités
The intern will perform the following tasks :
- Review of the existing recent literature on related topics, e.g. [1, 2]
- Creation of a simulated audio dataset corresponding to the considered audio augmented reality scenario, using available acoustic simulators such as [3]
- Development, training and testing of a deep neural network for the estimation of acoustical properties from these data, following previous works such as [4] and [5].
The intern will benefit from the strong expertise of the team MULTISPEECH in deep learning, acoustics and audio signal processing methodologies.
