Cool stuff at the Audio Engineering Society Convention in Berlin

aesberlin17_IDS_headerThe next Audio Engineering Society convention is just around the corner, May 20-23 in Berlin. This is an event where we always have a big presence. After all, this blog is brought to you by the Audio Engineering research team within the Centre for Digital Music, so its a natural fit for a lot of what we do.

These conventions are quite big, with thousands of attendees, but not so big that you get lost or overwhelmed. The attendees fit loosely into five categories: the companies, the professionals and practitioners, students, enthusiasts, and the researchers. That last category is where we fit.

I thought I’d give you an idea of some of the highlights of the Convention. These are some of the events that we will be involved in or just attending, but of course, there’s plenty else going on.

On Saturday May 20th, 9:30-12:30, Dave Ronan from the team here will be presenting a poster on ‘Analysis of the Subgrouping Practices of Professional Mix Engineers.’ Subgrouping is a greatly understudied, but important part of the mixing process. Dave surveyed 10 award winning mix engineers to find out how and why they do subgrouping. He then subjected the results to detailed thematic analysis to uncover best practices and insights into the topic.

2:45-4:15 pm there is a workshop on ‘Perception of Temporal Response and Resolution in Time Domain.’ Last year we published an article in the Journal of the Audio Engineering Society  on ‘A meta-analysis of high resolution audio perceptual evaluation.’ There’s a blog entry about it too. The research showed very strong evidence that people can hear a difference between high resolution audio and standard, CD quality audio. But this brings up the question of why? Many people have suggested that the fine temporal resolution of oversampled audio might be perceived. I expect that this Workshop will shed some light on this as yet unresolved question.

Overlapping that workshop, there are some interesting posters from 3 to 6 pm. ‘Mathematical Model of the Acoustic Signal Generated by the Combustion Engine‘ is about synthesis of engine sounds, specifically for electric motorbikes. We are doing a lot of sound synthesis research here, and so are always on the lookout for new approaches and new models. ‘A Study on Audio Signal Processed by “Instant Mastering” Services‘ investigates the effects applied to ten songs by various online, automatic mastering platforms. One of those platforms, LandR, was a high tech spin-out from our research a few years ago, so we’ll be very interested in what they found.

For those willing to get up bright and early Sunday morning, there’s a 9 am panel on ‘Audio Education—What Does the Future Hold,’ where I will be one of the panellists. It should have some pretty lively discussion.

Then there’s some interesting posters from 9:30 to 12:30. We’ve done a lot of work on new interfaces for audio mixing, so will be quite interested in ‘The Mixing Glove and Leap Motion Controller: Exploratory Research and Development of Gesture Controllers for Audio Mixing.’ And returning to the subject of high resolution audio, there is ‘Discussion on Subjective Characteristics of High Resolution Audio,’ by Mitsunori Mizumachi. Mitsunori was kind enough to give me details about his data and experiments in hi-res audio, which I then used in the meta-analysis paper. He’ll also be looking at what factors affect high resolution audio perception.

From 10:45 to 12:15, our own Brecht De Man will be chairing and speaking in a Workshop on ‘New Developments in Listening Test Design.’ He’s quite a leader in this field, and has developed some great software that makes the set up, running and analysis of listening tests much simpler and still rigorous.

From 1 to 2 pm, there is the meeting of the Technical Committee on High Resolution Audio, of which I am co-chair along with Vicki Melchior. The Technical Committee aims for comprehensive understanding of high resolution audio technology in all its aspects. The meeting is open to all, so for those at the Convention, feel free to stop by.

Sunday evening at 6:30 is the Heyser lecture. This is quite prestigious, a big talk by one of the eminent people in the field. This one is given by Jorg Sennheiser of, well, Sennheiser Electronic.

Monday morning 10:45-12:15, there’s a tutorial on ‘Developing Novel Audio Algorithms and Plugins – Moving Quickly from Ideas to Real-time Prototypes,’ given by Mathworks, the company behind Matlab. They have a great new toolbox for audio plugin development, which should make life a bit simpler for all those students and researchers who know Matlab well and want to demo their work in an audio workstation.

Again in the mixing interface department, we look forward to hearing about ‘Formal Usability Evaluation of Audio Track Widget Graphical Representation for Two-Dimensional Stage Audio Mixing Interface‘ on Tuesday, 11-11:30. The authors gave us a taste of this work at the Workshop on Intelligent Music Production which our group hosted last September.

In the same session – which is all about ‘Recording and Live Sound‘ so very close to home – a new approach to acoustic feedback suppression is discussed in ‘Using a Speech Codec to Suppress Howling in Public Address Systems‘, 12-12:30. With several past projects on gain optimization for live sound, we are curious to hear (or not hear) the results!

The full program can be explored on the AES Convention planner or the Convention website. Come say hi to us if you’re there!
