Bachelor Lecture:
Model-Based Algorithms for Retrospective Individualization of
Binaural Signals
With binaural signals, it is
possible to capture the sensation of spatial hearing that
humans are used to from real-life auditory scenes. However,
because binaural recordings are always individualized for a
specific target person, the authenticity of a binaural
recording is perceived differently by different listeners. It
is therefore desirable that a binaural recording is always
individualized for the respective listener.
In this thesis, the existing Binaural Cue Adaptation (BCA)
system from the Institute of Communication Systems is adjusted
and reinterpreted for it to be able to retrospectively
individualize an existing binaural signal for a new target
person. Existing approaches to the main components of the BCA
system, the Localization block and the Modification block, are
reviewed and analyzed and multiple new concepts and ideas are
introduced and algebraically described: New optimization
target functions, a concept for joint optimization over
multiple frequencies and multiple approaches that attempt to
lessen the impact of artifacts which may occur due to model
mismatches and / or erroneous location estimates.
A theoretical evaluation is conducted in which the
localization performance of both existing and new approaches
is benchmarked. The results confirm that some of the newly
proposed ideas and concepts improve the overall performance of
the BCA system.
All interested parties are cordially invited, registration is not required.
