DAFx Day 3

Day three of the Digital Audio Effects Conference (DAFx15) began with an excellent introduction and summary of Wave Digital filters and Digital Wave Guides by Kurt Werner and Julius O. Smith from CCRMA, in which the current state of the art in physical modelling no nonlinearities was presented and some potential avenues for future exploration was discussed. Following on from this work was discussed

DAFx Conference 2015

The DAFx conference began with a tutorial day, where Peter Svensson provided a fantastic summary of the State of the Art in sound field propagation modelling and virtual acoustics.

Slide from DAFx 15 Day 1

During lunch, as it was getting dark, the snow started, which unfortunately blocked our view on the Northern Lights that afternoon. Øyvind Brandtsegg & Trond Engum then discussed Cross adaptive digital audio effects and their creative use in live performance. He referenced existing work at Queen Mary as some of the state of the art in existing work, and then presented NUTU’s current work on Cross Adaptive Audio Effects. The workshop day was rounded off with Xavier Serra discussing the Audio Commons project and use of open audio content.

 

Upcoming Events

There are a range of interesting and exciting events that are upcoming in the field audio technology, including:

Listening in the Wild – A machine listening workshop hosted at Queen Mary University on the 25th of June. This will discuss how animals and machines can listen to complex soundscapes. More information here: http://www.eecs.qmul.ac.uk/events/view/listening-in-the-wild-animal-and-machine-hearing-in-multisource-environment

Intelligent Music Production – A workshop presented at Birmingham City University on the 8th September on the current state of the art in audio production technology, perception and future implications. Details are here: http://www.aes-uk.org/forthcoming-meetings/aes-midlands-workshop-on-intelligent-music-production/

Both of these events are free to attend, and promise to look very exciting indeed.

Visiting Researcher

Over the past month, I have been working closely with visiting researcher Luca Turchet [http://www.lucaturchet.it/].

We have been working on perceptual evaluation of synthesised footstep sounds. Within the experiment that we ran, participants put on shoes with sensors mounted in them. The sound of different floor surfaces and shoe types is then synthesised, through quality noise blocking headphones, and the participants are then asked to shape the spectral content with the aid of some very basic audio filters.

The intended outcome is to identify the extent to which different participants will vary the spectral characteristics of their footsteps.

Further updates on this research to follow.
