AES 140 – Paris

Last weekend saw the 140th Convention of the Audio Engineering Society — Europe’s largest gathering of audio professionals from around the globe, take place at Paris’ Palais des Congrès. From cutting edge research to fundamentals to practical application, the four-day technical program brings the opportunity to network with and learn from leading audio industry luminaries. Special events — including technical tours of premier production facilities and installs, student focused sessions and a 3 day manufacturer exposition round out the Convention. There was a particular focus on 3D and immersive audio at this Convention.

I was responsible for running all aspects of the student track of the convention, including Education and Career Fair, Student Design Competition, Recording Competitions and the Education Committee Meetings. At the end of the Convention I was promoted to Chair of the Student Delegate Assembly for Europe and International Regions.

AES61 Audio for Games

The 61th International Conference of the Audio Engineering Society on Audio for Games took place in London from 10 to 12 February. This is the fifth edition of the Audio for Games conference which features a mixture of invited talks and academic paper sessions. Traditionally a biennial event, by popular demand the conference was organised in 2016 again following a very successful 4th edition in 2015.

Christian Heinrichs presented work from his doctoral research with Andrew McPherson, discussing Digital Foley and introducing FoleyDesigner, which allows for effectively using human gestures to control sound effects models.

I presented a paper in the Synthesis and Sound Design paper session, on weapon sound synthesis and my colleague William Wilkinson presented work on mammalian growls, both of which can be found in the conference proceedings.  

Furthermore, Xavier Serra and Frederic Font presented the Audio Commons project and how the creative industries could benefit from and get access to content with liberal licenses

Along with presenting work at this conference, I was also involved as the technical coordinator and webmaster for the Audio for Games community.

More information about the conference can be found on the conference website.

AES Presentation on Owl Guitar Pedal

Martin Klang presented a talk on Open Source Entrepreneurship and the OWL discussing the OWL guitar pedal, creation through to production.

He discussed how the crowd funding sources, how to budget for small start up projects. The importance of open source, both in terms of software and hardware was discussed at length, and is a vital aspect of what the OWL team set out to do.

The OWL is a custom build programmable guitar effects pedal that allows anyone to write their own effect pedal and load it onto the standalone program. Effects can be written in C++, Faust or even Pure Data (PD). There is also a wrapper that allows users to run their patches as a VST or AU within a Digital Audio Workstation and in the future, it will also be possible to run patches in the browser. Recently a modular synthesiser version of the Owl has also been released.

Dereverberation

I have been accepted to publish my MSc project on Dereverberation applied to Microphone Bleed Reduction.

I implemented existing research in reverb removal and combined with with a method for microphone interference reduction. In any multiple source environment there will interference from opposing microphones as pictured below.2s2m

Research at Queen Mary University allows this interference to be reduced in real time processing and my project was to improve this with the addition of removing natural acoustic reverberation in real time, to assist with the microphone bleed reduction.

This work will be published at the AES conference on DREAMS (Dereverberation and Reverberation of Audio Music and Speech).

AES on Intelligent Music Production

Yesterday, the AES presented a workshop on Intelligent Music Production. The day started with a great discussion of the current state of the art of Intelligent Music Production, with strong indications as to where the future of the research will occur, provided by Josh Reiss. Hyunkook Lee presented some interesting work on 3D placement of sources in a mix, and how to separate tracks based on the perceived inherent height of different frequency bands. Brecht De Man discussed his PhD work on subjective evaluation of music mixing, and his path to understand how people go about producing their preferred mix of music, and how this is perceived by others.

Following this, Sean Enderby provided an energetic talk on a set of SAFE tools produced at BCU for attaching semantic terms to presets for a range of audio effect plugins. Alessandro Palladini from Music Group UK, presented their current work on “Smart Audio Effects for Live Audio Mixing” which included interesting work on multiple side chained and parameter reduced effects and new methods and tools to provide mix engineers, both in the studio and in live music scenarios. Their research is focused around providing an intuitive set of tools that remain perceptually relevant. Alex Wilson presented his work on how participants mix a song in a very simplified mix simulation and how the starting positions will impact the final mix that participants will produce.

Videos of all the presentations is available here: http://www.semanticaudio.co.uk/media/

AES Workshop on Intelligent Music Production

The 8th September 2015 sees the Audio Engineering Society UK Midlands Section presenting a workshop on Intelligent Music Production at Birmingham City University.

As ever, C4DM have a strong presence at this workshop, as two of the six presented talks are by current C4DM members. Ryan Stables, the event organiser, and others at the Digital Media Technology (DMT) Lab in Birmingham City University are currently collaborating with C4DM on the Semantic Audio Feature Extraction (SAFE) project. More information on this project can be found here

Josh Reiss will present a summary of the current state of the art in Intelligent Music Production, highlighting current research directions and the implications of this technology. Brecht De Man will present some of his PhD results in perceptual evaluation of music production as he attempts to understand how mix engineers carry out their work. Further to this, Alex Wilson was a previous C4DM visiting student for six months, and will be presenting his recently publishing work from Sound and Music Computing Conference, in navigating the mix space.

Next Generation Sound Synthesis

Yesterday I attended an AES presentation on the NESS Project by Stefan Bilbao. The NESS project is the “Next Generation Sound Synthesis” project, as a 5 year European Research Funded project, undertaken by University of Edinburgh.

The aim of this project is to explore the possibilities of simulation based synthetic sounds using high performance computing clusters. Numerical simulation methods for physical modelling were presented, with a focus on Finite Difference Time Domain methods for modelling of musical instruments.

The presentation focused on a range of different fields, and presented the state of the art in physical modelling. The advantages of this modelling technique is the possibilities of creating ‘impossible’ instruments, such as a brass instrument that is too large to physically play, but it is still possible to model how it would work with infinite resources or infinite lung capacity.

Brass Instruments, bowed and picked string instrument, and percussion models were all presented, along with physical modelling of acoustics through finite difference and volume models.

AES-Warsaw

I have spent the past five days at the Audio Engineering Society convention in Warsaw, where I stood to become vice chair of the AES Student Delegate Assembly for European and International Regions.

The Student Delegate Assembly representatives are a group of four students (two for European and International Regions and two for North and Latin America ) who support students who attend the AES convention, answer student queries, coordinate independent student events and student events at all conventions, represent the student members of the AES within the Education Committee and as part of the AES as a whole. Events run at the convention include Student Recording Competition, Student Design Competition, Student Party, an opening and closing student meeting, and an Education and Career Fair where institutions and companies can exhibit, promote and recruit to students for free. Whilst at the AES convention I also represented Queen Mary at the Education Fair, focusing on Queen Marys new Sound and Music Computing MSc programme.
