Postdoctoral researcher Alexander Refsum Jensenius has updated the AudioAnalysis software to version 0.5 (previously SoundAnalysis). The new version provides a larger spectrogram view, and the option to change various spectrogram features on the fly. The quantitative features have been moved to a separate window, and now also includes simple beat tracking.

All in all, the new version of AudioAnalysis provides basic sound visualisation and plotting of some perceptually relevant features. See the software web page for screenshots, a tutorial video and the program files (for both OSX and Windows).

Title: Making Sensors Make Sense: Challenges in the Development of Digital Musical Instruments

Abstract: Despite the fact that digital technology has become an inevitable tool in music production and distribution during the course of the past few decades, live performers of digital musical instruments (DMIs) remain enigmatic to a majority of music audiences. A combination of instrument design issues, limits to the human cognitive system, and cultural constraints may all be contributing factors to these circumstances. This thesis presents a theoretical overview of some challenges in the development of DMIs, weighed against an empirical study based on qualitative research interviews with six DMI performers. Additionally, instrument types are categorized according to the order of separation between action and sound when performing with the instrument (incorporated, direct, mechanical, analog electronic and digital), and a hypothesis regarding the influence of instrument types on the music cognition of performers is tested.

We have a paper entitled "fourMs, University of Oslo – Lab Report" in the Proceedings of the 2010 International Computer Music Conference, New York, NY, 1–5 June 2010. [PDF]

Authors: Jensenius, A.R., Glette, K., Godøy, R.I., Høvin, M., Nymoen, K., Skogstad, S.A., Tørresen, J. (2010)

Abstract: The paper reports on the development and activities in the recently established fourMs lab (Music, Mind, Motion, Ma- chines) at the University of Oslo, Norway. As a meeting place for researchers in music and informatics, the fourMs lab is centred around studies of basic issues in music cogni- tion, machine learning and robotics.

Publication: Godøy, R. I., Jensenius, A. R., and Nymoen, K. (2010). Chunking in music by coarticulation. Acta Acoustica united with Acoustica, 96(4):690–700. [Fulltext]

Abstract: In our own and other research on music-related actions, findings suggest that perceived action and sound are broken down into a series of chunks in people's minds when they perceive or imagine music. Chunks are here understood as holistically conceived and perceived fragments of action and sound, typically with durations in the 0.5 to 5 seconds range. There is also evidence suggesting the occurrence of coarticulation within these chunks, meaning the fusion of small-scale actions and sounds into more superordinate actions and sounds. Various aspects of chunking and coarticulation are discussed in view of their role in the production and perception of music, and it is suggested that coarticulation is an integral element of music and should be more extensively explored in the future.

Just tagged a new release of the Jamoma GDIF tools.

It can be downloaded from by following the instructions on our software website, or using this direct link.

The changes are mainly small bug changes and updating the stream types, but also adding user-adjustable time tag delay (by sending the /timeTagDelay message to the module).

We are happy to announce that Arve Voldsund has started as 50% research engineer in the group. He will work on standardisation (GDIF), storage and retrieval of music-related movement data.

Cynthia M. Grund, Network Coordinator for NNIMIPA, has posted a page with pictures and videos of the motion capture session done with American pianist William Westney during his visit to Oslo in February. There are also links to a video recording of a small discussion between Cynthia Grundt, William Westney and Alexander Refsum Jensenius on some of the topics discussed during the NNIMIPA workshop in Oslo.

This week's edition of the University of Oslo newspaper Uniforum features a story called "Forskar mellom kunst og vitskap" ("Research between art and science"), highlighting the importance of interdisciplinarity in research.

The interview was made in connection with a performance of the piece Transformation at Norwegian Academy of Music a couple of weeks ago. By moving inside a seemingly empty space, the violinist slowly explores a sonic landscape of thousands of short fragments of various violin sounds. The space thus becomes a musical entity in itself, a space that the violinist both controls and interacts with at the same time. What seemed to be an empty space at first, is left as a sonic space in our memory when the piece ends.

Postdoctoral researcher Kyrre Glette participated in (and won!) the 64kB intro competition at the Assembly computer festival in Helsinki. A 64kB intro is an executable program in 64kB which includes realtime generation of graphics and music.

The animation includes a dancing robot, where the motion is based on data recorded with our new Qualisys infrared motion capture system.

Graphics programming done by Kim Kalland, Thomas Kristensen and Kyrre Glette. Sound programming and music by Gergely Szelei-Kis.

Our new motion capture system is presented in the Qualisys newsletter from May. We have been working with Qualisys to create an integrated solution for handling recording and streaming of music-related body movement data, and look forward to working with the new system in the coming years!
