Project C2 - Audio reproduction in non-optimal acoustical environments
Audio content is commonly reproduced over loudspeakers in reverberant and noisy environments. This often leads to non-optimal reproduction conditions. Impairments can both be with respect to the spatial and timbre fidelity of the reproduction as well as with respect to speech intelligibility. This project will focus on robust methods for compensating for the non-optimal acoustical conditions and hearing capabilities of the listeners that can be applied in multiple scenarios.
Of specific interest will be supporting technology employed in daily life for audio and speech reproduction in entertainment and public address systems as well as methods for low hardware footprint solutions for rendering complex acoustic scenes in laboratory settings.
