Audio signal processing

The field of audio signal processing includes the recording, analysis, processing and reproduction of audio signals.

Rather than limiting ourselves to language and music as the usual wanted signals, we are expanding our focus to include ambient noise. Besides base algorithms and techniques, such as filter banks (gammatone, WOLA), spectral analysis and filter optimisation, the work also focuses on computational auditory scene analysis (CASA), signal enhancement and signal reproduction. This topic is concerned with the development of algorithms for processing audio signals and with optimising the implementation of this.
