Dynamic Range Limiting of HRTFs: Principle and Objective evaluation

Hervé Lissek, Patrick Marmaroli, Gilles André Courtois, Lukas Rohr

This research addresses the challenge of incorporating dynamic range limiting of the magnitude response of HRTFs for hearing-impaired listeners who are using binaural hearing aids. In this application, a direct implementation of spatialization using the or ...

Evaluation of audio source separation in the context of 3D audio

Lukas Rohr

The emergence and broader availability of 3D audio systems allows for new possibilities in mixing, post-production and playback of audio content. Used in movie post-production for cinemas, as special effect by disk jockeys for example and even for live con ...

Vertical localization performance in a practical 3-D WFS formulation

Hervé Lissek, Lukas Rohr

Vertical localization performance in a practical wave field synthesis formulation is investigated. The implemented 3-D rendering method allows precise sound source reproduction while taking into account practical constraints such as the required number of ...

Caractérisation acoustique spatiale de salles : étude énergétique des premières réflexions

Hervé Lissek, Xavier Falourd, Lukas Rohr

Toute production de musique ou de parole dans un espace clos fait intervenir en amont des questionnements d’acoustique. Pour offrir à l’auditeur des conditions d’écoute optimales, l’acousticien utilise des descripteurs caractérisant le champ sonore. Les mé ...

Spatial echogram analysis of a small auditorium with observations on the dispersion of early reflections

Hervé Lissek, Xavier Falourd, Lukas Rohr

Classical room acoustics are based on the interpretation of different sound attributes such as reverberation time, clarity and spatial decay. Based on echograms calculated from a microphone array, the dispersion of early reflections is measured and the ref ...
