Department of Signal Processing and Acoustics

Audio signal processing

The Audio Signal Processing Research Group is working on wideband sound technology, which is extensively applicable for example in smart phones, music technology, gaming, sound reproduction, and noise control.
Acoustic measurements at the Aalto Acoustics Lab

Our research topics and projects are related to headset signal processing, loudspeakers, sound synthesis, effects processing algorithms, digital filters, musical instruments, acoustic measurements, subjective evaluation, and interactive audio systems. The emphasis of our research is on digital signal processing and machine learning methods which account for the properties of human hearing. We collaborate with several companies, such as Genelec and Nokia Technologies. Much of our academic research is conducted in collaboration with foreign partners, such as Aalborg University, The University of Edinburgh, and Stanford University.

This research group organizes the Audio Signal Processing course at Aalto University annually in January-April. We also arrange the Acoustics and Audio Technology Seminar every second year (February-May). Both courses are suitable for Master's and doctoral students, who have a solid background in acoustics and digital signal processing. Additionally, we are responsible for the Noise Control course for Master's and doctoral students and for the Applied Digital Signal Processing course for BSc students.

The Audio Signal Processing Research Group belongs to the Aalto Acoustics Lab. The research group is led by Professor Vesa Välimäki, IEEE Fellow, AES Fellow.
