Following the argument in Röbel, “Between Physics and Perception: Signal Models for High Level Audio Processing”, a fundamental requirement for these transformation algorithms is their need of signal models that are strongly linked to perceptually relevant physical properties of the sound source. This paper is a short survey about the phase vocoder technique, together with its extensions and improvements relying on appropriate sound models, which have led to high level audio processing algorithms.}, journal={Musica/Tecnologia}, author={Liuni, Marco and Röbel, Axel}, year={2013}, month={Aug.}, pages={73–89} }
