Sounds in Space 2014 – 30th June

Our yearly Sounds in Space symposium is shaping up to be a great event.  We have a talk from the BBC’s Chris Pike confirmed as the keynote (on object-based broadcasting with examples played over our 20 speaker 3D rig) and further talks on subjects such as surround bone conduction audio, multi-channel internet streaming and live, large scale surround sound composition and implementation.  We still have spaces for more talks, so please send short abstracts to b.j.wiggins@derby.ac.uk by 5pm on Monday 19th May 2014.

Sounds In Space Poster 2014

Live demos and surround works are actively encouraged (we’ll have a 20 speaker 3D rig available in the presentation room – I can provide a Higher Order Ambisonic Decoder if necessary).

We’ve also got plenty of spaces left for attending this free event.  If you’re interested in attending or presenting at what’s always a great day, please see this page for more details.

Visualisation Test


Below this should be a visualisation of 1st, 2nd and 3rd order Ambisonics (click the mouse to change order).  This is showing the velocity and energy vector analysis of a velocity vector optimised decoder, but you’ll still notice the energy vector magnitude improving with rising order.

White blob is the source (size equates to amplitude) and red blobs are the speakers (which go blue when they’re out of phase). The orange and green ‘blips’ are the energy and velocity vectors respectively. Buttons to start and stop the animation at underneath…


Play Controls :

These controls currently aren’t working as WordPress is stripping out some of my HTML (it didn’t when I originally posted it)…… not a massive issue, so I’m not fixing for the moment!

OSX and Mavericks Fixed Plug-ins

I’ve uploaded two plug-ins which should fully work with Mavericks (on a side note, the old plug-ins still work fine with Plogue Bidule, it’s just Audiomulch and Reaper that exhibit identical issues.)

A 1st, 2nd, 3rd and 4th order 5.0 ITU decoder is available and should demonstrate the fix (and I’ve made it available for PC too!)  Available on the WigWare page, or below!

Buxton to Derby Sponsored Bike Ride

On Friday 12th July I’ll be doing a sponsored bike ride from Buxton to Derby in aid of Dogs for the Disabled. As I did a couple of years ago, my progress can be tracked in real time on the page below, or instructions on how to keep tabs in google earth too! If you fancy sponsoring me, instructions are also on the page below 🙂 My public location won’t update much except for testing until the day!

Sounds in Space 2013 – Call for Participation

After the success of the previous three Sounds in Space events help at the Markeaton Street Campus of the University of Derby, we’re hosting the event again….and it’s still free!

Sounds In Space 2013 PosterThe symposium concentrates on practical audio/audio-visual demonstrations and the transfer of knowledge through interactive presentations and Q & A sessions and will be of interest both to practitioners in the field and industry as well as the academic community interested in surround audio and it’s related fields.  To this end, the previous events have been a mixture of academic and practitioners in industry presenting, which aim to continue this year!

If you’re interested at presenting/demonstrating at the event, please email me at b.j.wiggins@derby.ac.uk by 5pm on Monday 27th May 2013. Abstracts should be around 150 words in length and submitted as a standard Word document.   Please also provide a 100 word personal summary (for potential public dissemination!) for all contributing personnel.   For more details, please look at the Sounds in Space 2013 Page, which also includes a link to the call for works and other details PDF (or you could just click >HERE<).

Any questions/comments?  Feel free to ask here!

If you interested in attending the event, it’s FREE, and light refreshment and lunch is also provided.  To register for a place (numbers are limited) please email Jessamie Self at j.m.self@derby.ac.uk 

Celestial Dynamics Audio-Visual Installation – Stargazing Live 2013

If you’re lucky enough to be going to the Stargazing live event at University of Derby (see here and here) then you’ll also get the chance to experience Celestial Dynamics, a higher order Ambisonic and visual installation setup in the Markeaton Street building.  Developed by Michael Brown, and using the WigWare higher order Ambsionic plugins and source material from the Hubble Space Telescope and Voyager 2 recordings.  If you’re attending this free event, it’s running MS017 🙂  Some stills from the video are shown in this post, and the poster to be shown alongside the installation can be found at:

2nd and 3rd Order WigWare

I’ve currently got up to 4th order versions of my panners and decoders.  Attached to this post is a link to the 2nd and 3rd order Panners (encoders).  There are two versions of each order:

  • A 2D 2nd order version that outputs 5 channels of 2nd order Ambisonic goodness (W,X,Y,U & V)
  • A 3D version that outputs 9 channels (W,X,Y,Z,R,S,T,U & V)
  • A 2D 3rd order version that outputs 7 channels (W,X,Y,U,V,P & Q)
  • A 3D 3rd order version that outputs 16 channels (W,X,Y,Z,R,S,T,U,V,K,L,M,N,O,P & Q)
These panners use the Furse Malham weightings.  More info can be found here.

If NFC (near field compensation) is set to OFF then as the source is moved into the middle, the directional compenents are turned down (centre sources comes out of every speaker equally when decoded). If NFC is set to a distance, then the
distance parameter then controls the distance filtering which applies LF boost (proximity effect) as the source moves closer to the middle.

WigWare Ambisonic Plug-ins Update

I’ve updated the PC versions of my 1st order plugins to incorporate a number of bug fixes already present in the Mac versions.  I’ve also optimised the code a little, and improved the near field compensation and distance filtering to be, well, correct and glitch free (not very noticeable in 1st order….2nd order to come!)  Also, these are now compiled using Microsoft Visual Studio as Audacity didn’t like Borland Builder compiled versions……

Sounds in Space 2012

We have a programme change in the Sounds in Space 2012 event.  We are pleased to announce that John Crossley will be talking to us about the 5.1 mix he carried out for Imogen Heap (called Neglected Space which was featured on the Xizi She Knows single) which utilised both Pro-tools and 4th order Ambisonics.  It’s not too late to register for the event!  See details here!
