PhD position in audio signal processing KU Leuven
The spatial information contained in recorded microphone signals has a fundamental role in the characterization of acoustic environments. Furthermore, it can be exploited in digital audio processing frameworks for enhancing a desired source signal, benefiting applications such as hands-free telephony, hearing devices, human-machine interfaces, and acoustic monitoring systems. Despite its acknowledged relevance, accurately estimating and ...
Multi-modal signal processing algorithms for extraction of coupled sources in combined audio and EEG recordings. KU Leuven
One in five experiences hearing loss. The World Health Organization estimates that this number will increase to one in four in 2050. Luckily, effective hearing devices such as hearing aids and cochlear implants exist with advanced noise suppression and speaker enhancement algorithms that can significantly improve the quality of life of people suffering from hearing loss. State-of-the-art hearing devices, however, underperform in a so-called ...
Distributed Digital Signal Processing for Ad-hoc Wireless Local Area Audio Networking KU Leuven
Audio based home monitoring system for the elderly KU Leuven
The pending retirement of the babyboom generation will put a strain on the elderly care support system. In particular, there will be a lack of qualified personnel to provide home care and also insufficient space in elderly care facilities. Technology integrated in the elderly’s home could help ease this burden. Firstly, this technology could keep an eye on things, reassuring the person's safety at home. In such a situation, the person can ...
SONORA: The Spatial Dynamics of Room Acoustics. KU Leuven
The SONORA project aims to increase the general understanding of how complex sound scenes are impacted by the spatial dynamics of room acoustics. This knowledge is crucial in the design of signal processing algorithms for audio acquisition and reproduction problems in real-life situations, where moving sound sources and observers interact with room acoustics in a complicated manner.
A major part of the project will be devoted to the ...
Estimation of nonstationary spatial noise maps for acoustic signal enhancement and detection KU Leuven
The SOUNDS European Training Network (ETN) revolves around a new and promising paradigm coined as Service- Oriented, Ubiquitous, Network-Driven Sound. Inspired by the ubiquity of mobile and wearable devices capable of capturing, processing, and reproducing sound, the SOUNDS ETN aims to bring audio technology to a new level by exploiting network-enabled cooperation between devices. We envision the next generation of audio devices to be capable ...
Multi-microphone Speech Enhancement: An Integration of A Priori and Data-dependent Spatial Information KU Leuven
A speech signal captured by multiple microphones is often subject to a reduced intelligibility and quality due to the presence of noise and room acoustic interferences. Multi-microphone speech enhancement systems therefore aim at the suppression or cancellation of such undesired signals without substantial distortion of the speech signal. A fundamental aspect to the design of several multi-microphone speech enhancement systems is that of the ...
Spatial recording, processing, and auralization of church acoustics KU Leuven
This PhD research aims to design, implement and evaluate a methodology for the recording, processing and auralization of church acoustics. A mobile measurement setup and protocol will be developed and used to initiate a database of spatial acoustic recordings in various churches that are historically relevant to the performance of plainchant music. Signal processing algorithms for the spatial analysis, modeling, and synthesis of these ...
