Audio signal processing

The Audio Signal Processing Research Group is working on wideband sound technology, which is extensively applicable for example in mobile phones, music technology, and noise control.
Aalto-yliopisto, liput / kuvaaja: Aino Huovio

Our research topics and projects are related to headphone signal processing, sound synthesis and 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 methodology which accounts for the properties of human hearing. Much of our academic research is conducted in collaboration with foreign partners, such as Stanford University.

The research group is led by Professor Vesa Välimäki.
