The Mathematics Cluster of the Acoustics Research Institute of the OeAW invites to a workshop about the Large Time-Frequency Analysis Toolbox (LTFAT), that is being developed at the institute. The toolbox offers state-of-the-art implementations of common algorithms for time-frequency analysis, many of which having been devised at the institute. Thus, they enable other researchers to review and build upon research results.
This workshop gives a hands-on introduction to creating time-frequency representations of audio signals with the Large Time-Frequency Analysis Toolbox (LTFAT) for MATLAB and Octave. We will have a particular focus on the construction and use of filterbanks. No previous knowledge about the LTFAT is required.
The workshop is expected to last approximately 3 hours, with an open end. Snacks (with vegetarian options) and drinks will be provided. If you are interested, we kindly ask you to register.
If you have successfully registered, remember to bring your laptop equipped with either MATLAB or Octave and your favorite audio recordings.
Schedule of the workshop:
- What is LTFAT + installation
- Introduction to filterbanks + construction of a constant-Q filterbank step-by-step using cqtfilters
- Build an awesome Gammatone filterbank on your own using audfilters
- (If time permits) Time-frequency reassignment and phase retrieval
This event is sponsored by the Institute of Electrical and Electronics Engineers (IEEE) and the Acoustics Research Institute (ARI) of the Austrian Academy of Sciences (OeAW).
