Univ.-Prof. Alex Hofmann, PhD

Alex Hofmann is a professor in music acoustics at the University of Music and Performing Arts Vienna, sound artist and saxophone/live-electronics performer working with improvised and contemporary music, currently as the principal investigator (PI) of the FWF-PEEK project Études for Live-electronics. He investigates tools and methods to enhance expressiveness in music performance by advancing new sensor technologies and developing dedicated computer algorithms.

He had previously done research at the Austrian Research Institute for Artificial Intelligence (OFAI), taught at different institutions (e.g. Dept. of Musicology, Vienna University), worked as a Teaching Assistant at the TU Berlin (Audio Communication Group), as well as a Sound Design Assistant at Native Instruments.

As an active member in the Csound (computer music language) community, he worked as a co-editor for the books “Csound Floss Manual” (Heintz et al., 2011), and “Ways Ahead - Proceedings of the First International Csound conference” (Heintz et al., 2013), which document Csound’s open-source software development towards real-time sound synthesis in the last 25 years.

In his Ph.D., Alex analyzed motor-actions in clarinet and saxophone performance using miniaturized sensor-technology and advanced signal processing methods. He presents artistic work and research results in concerts or spoken presentations as well as in workshops at venues such as the Akademie der Künste Berlin (DE), Berklee College of Music (Boston, US), BEK (Bergen Center for Electronic Arts, NO), ZKM (Karlsruhe, DE), RADIALSYSTEM V (Berlin, DE) and maintains active exchange with computer music communities such as the Linux Audio Community and NIME.

Current Projects:

  • Études for Live-Electronics (funded by FWF-PEEK) is an artistic research project that aims to re-define the western classical music-influenced concept of études, by applying it to the diverse practices in the field of electronic music performance. (2022–25)

  • VRACE - Virtual Reality Audio for Cyber Environments This project focuses on the analysis, modelling and rendering of dynamic 3-dimensional soundscapes for applications in Virtual and Augmented Reality. 17 academic and industrial partners strive to make significant progress on the way towards a physically correct virtual reality and thus towards a true world simulation. (2018-23)

  • Towards an alliance for distributed ethnomusicology data (funded by ASEA-Uninet, 2018-2022; project lead: MDW) This project will examine the current situation of data sets in ethno-musicology towards the development of standardized ways for data storage and data access between partner organizations. To this end, we plan to form an initial alliance that collects the requirements for an interoperable data infrastructure for digital musicology projects in the South-East Asian region and builds first examples of tentative applications by means of automatic content and metadata analysis. Goal of the project is to design a strategy that allows the storage of data sets in a standardized way that supports an exchange of (meta) data between partner organizations.

Past Projects:

  • INSYNC During my time at the Austrian Research Institute for Artificial Intelligence (OFAI), I worked in a research group lead by Dr. Werner Goebl on “Synchronization and Communication in Music Ensembles”.

  • FWF-Clarinet This FWF-founded project on the “Measurement of finger forces in clarinet playing” was lead by Dr. Walter Smetana from the Institute of Sensor and Actuator Systems at TU-Wien and Dr. Werner Goebl (IWK, mdw) as National Research Partner.
