This international, multi-disciplinary and team-oriented project will expand the group Mathematics and Acoustical Signal Processing at the Acoustic Research Institute in cooperation with NuHAG Vienna (Hans G. Feichtinger, M. Dörfler, K. Gröchenig), Institute of Telecommunication Vienna (Franz Hlawatsch), LATP Marseille (Bruno Torrésani) LMA (Richard Kronland-Martinet). CAHR (Torsten Dau, Peter Soendergaard), the FYMA Louvain-la-Neuve (Jean-Pierre Antoine), AG Numerics (Stephan Dahlke), School of Electrical Engineering and Computer Science (Damian Marelli) as well as the BKA Wiesbaden (Timo Becker).
- Kick-off workshop (Vienna, 7.-8.May 2012)
- Mid-term workshop (Marseille, 18.-20-November 2014)
- FLAME Physics workshop (Vienna, 21.-22.Oktober 2015)
We live in the age of information where the analysis, classification, and transmission of information is f essential importance. Signal processing tools and algorithms form the backbone of important technologieslike MP3, digital television, mobile phones and wireless networking. Many signal processing algorithms have been adapted for applications in audio and acoustics, also taking into account theproperties of the human auditory system.
The mathematical concept of frames describes a theoretical background for signal processing. Frames are generalizations of orthonormal bases that give more freedom for the analysis and modificationof information - however, this concept is still not firmly rooted in applied research. The link between the mathematical frame theory, the signal processing algorithms, their implementations andfinally acoustical applications is a very promising, synergetic combination of research in different fields.
Therefore the main goal of this multidisciplinary project is to
-> Establish Frame Theory as Theoretical Backbone of Acoustical Modeling
in particular in psychoacoustics, phonetic and computational acoustics as well as audio engineering.
For this auspicious connection of disciplines, FLAME will produce substantial impact on both the heory and applied research.
The theory-based part of FLAME consists of the following topics:
- T1 Frame Analysis and Reconstruction Beyond Classical Approaches
- T2 Frame Multipliers, Extended
- T3 Novel Frame Representation of Operators Motivated by Computational Acoustics
The application-oriented part of FLAME consists of:
- A1 Advanced Frame Methods for Perceptual Sparsity in the Time-Frequency Plane
- A2 Advanced Frame Methods for the Analysis and Classification of Speech
- A3 Advanced Frame Methods for Signal Enhancement and System Estimation
