ABSTRACT A framework for real-time expressive modification of audio musical performances is presented. An expressiveness model compute the deviations of the musical parameters which are relevant in terms of control of the expressive intention. The

High-order sparse linear predictors for audio processing
free download

ABSTRACT Linear prediction has generally failed to make a breakthrough in audio processing, as it has done in speech processing. This is mostly due to its poor modeling performance, since an audio signal is usually an ensemble of different sources.

Biologically inspired auditory attention models with applications in speech and audio processing
