Testing real-time capable audio algorithms in a time-variant acoustic environment can be a tedious process, often requiring specialised hardware to fulfil latency constraints. In this publication, an alternative approach based on an acoustic scene simulation in TASCAR and signal processing using FAUST is assessed and tested against actual measuremen...

This paper investigates the perceived spatial extent of a local active noise control system for different types of disturbances. Several publications determined size and shape of the zone of quiet for various arrangements through analytical and numerical methods. However, these studies have often overlooked human perception, focusing solely on tech...

The constant-Q transform (CQT) is a valuable tool for music information retrieval, e.g. for chroma calculation and harmonic analysis. In this E-Brief, we propose a block based, real-time capable, efficient analysis algorithm resting upon a subsampling technique performed with fast Fourier transform. In addition, advanced features such as time resol...
