Audio signal classification suffers from the mismatch of environmental conditions when training data is based on clean and anechoic signals and test data is distorted by reverberation and signals from other sources. In this contribution we analyze the classification performance for such a scenario with two concurrently active sources in a simulated(More)
In 2011, Borß introduced a parametric model for the design of virtual acoustics, which creates a natural sounding virtual environment for applications requiring virtualization e.g., in teleconferencing systems and computer games. In this work we refine this model to make it applicable for the simulation of room acoustics and reverberation to aid in(More)
We present here a hierarchical approach for the detection and localisation of brake squeal. The proposed system exploits the spatial diversity of microphone arrays to localise a squealing brake. As brake squeal is emitted from a priori known regions, i.e. near the wheels, localisation of a squeal may be seen as a hypothesis testing problem. However, in(More)
