Keywords
to make master II students acquainted with the fundamentals of the analysis-processing-synthesis techniques: Short Time Fourier Transform (STFT) and spectrogram. Perfect reconstruction conditions. Filter-bank and sliding-window Fourier transform interpretations. Time-frequency resolution trade-off (Heisenberg uncertainty principle). Extension to TFD filter-banks and wavelets (introduction). Equivalence between time warping and frequency warping. Temporal methods (OLA, PSOLA,…) for temporal and spectral modifications. - Additive synthesis based on a slowly time-varying sinusoidal+noise model. Automatic analysis chain including partial trajectory extraction. Noise modelling. Strategies and algorithms for sound computation whether based on partial trajectories. - Source-filter model for sound synthesis. Model typology; source and filter structures. Related sound analysis techniques. Classical analysis/processing/synthesis scheme based on the three aforementioned sound models. Related temporal and spectral sound processing techniques: time stretching, transposition, equalizer, noise extraction or reduction, cross-synthesis, sound morphing, - Lab sessions for practical and experimental study.

The European Acoustics Association (EAA) is a non-profit entity established in 1992 that includes in its membership societies predominantly in European countries interested in to promote development and progress of acoustics in its different aspects, its technologies and applications. EAA gathers 33 societies of acoustics and serves more than 9000 individual members all over Europe. The European Acoustics Association (EAA) is an Affiliate Member of the International Commission for Acoustics (ICA) and of Initiative of Science in Europe (ISE).
