Hannes Helmholz

Doctoral Student at Applied Acoustics

Hannes Helmholz is a doctoral student at the Division of Applied Acoustics and part of the Audio Technology Group.

His research focuses on making established processing methods for audio signals accessible for real-time applications. This contains the reproduction of signals from spherical microphone arrays in particular over headphones. Perceptual influences on the quality of the spatial reproduction will be evaluated in multiple user studies. The achievements will eventually enable a new level of audio recording and reproduction for academia, industry and end users alike.
