While South Africa is busy getting their plastic horn on – the rest of the world has responded with a flurry of filtering techniques to keep the vuvu drones from our ears. Mostly the filtering is aimed at audio, but there are some implications for video too.
Buzzkill
Audio nerds the world over must love soccer, because there’s been a huge outpouring online of ways to filter out the drone. Create Digital Music have done a pretty great round-up of these, tackling everything from EQing with onscreen TV controls ( get rid of 233, 466, 932 and 1864 HZ if you can), free VST plug-ins for mac and pc, acoustic engineers explaining the science of why vuvzelas are annoying ( I actually enjoy the medieval carnival / sacrifice kinda vibe they add ), vuvuzela orchestra ( yes, really ), vuvuzela radio ( uhuh ), and how to re-route audio signals using JACK or Soundflower into another application that has better audio filtering and VST capacities.
Audio Re-Routing
Wormhole2 – allows routing of audio between machines on a network. Now you can make use of all the processing power in your studio. For example; set aside a machine for complex instruments or effects, route audio out to it, then back into your favorite DAW. Or route audio between your PCs and Macs to get the best of both worlds. Or share audio between laptops on stage.
Soundflower is a Mac OS X (10.2 and later) system extension that allows applications to pass audio to other applications. Soundflower is easy to use, it simply presents itself as an audio device, allowing any audio application to send and receive audio with no other support needed. Soundflower is free, open-source, and runs on Mac Intel and PPC computers. IS often used for podcasting to combine tow different audi streams, or to combine skip interview voices etc.
Jack (the Jack Audio Connection Kit ) is a low-latency audio server, written originally for the GNU/Linux operating system, and now with Mac OS X support. It can connect any number of different applications to a single hardware audio device; it also allows applications to send and receive audio to and from each other. Jack is different from other audio server efforts in that it has been designed from the ground up to be suitable for professional audio work. This means that it focuses on two key areas: synchronous execution of all clients, and low latency operation.
Video Re-Routing?
But let’s say you want to send a video signal from one program into another program – how to do that? No such re-routing software currently exists, but there is at least a work around through Vade’s excellent ( and free ) Screen Capture utility. This is a Quartz Composer patch ( and therefore mac only) which allows a portion of the screen to be selected, then sent into another compatible program. This can mean web browsing / web-flash games / computer games etc can all be displayed in one corner of a screen, and then accepted within VJ software such as VDMX and used as a live signal, and filtered, mixed or processed to your heart’s content. ( Be warned : Removing plastic horns visually is likely a bit trickier… )
But Wait, There’s More..
Vade has more in the pipeline, a video re-router that will work fast, and on the graphics card rather than CPU. Tests so far allow easy re-routing between Max MSP / Jitter / Quartz and VDMX. Bookmark his site for announcements to come. And in other news the Auvi Objects have been updated for Max 5, which will please live visualists who remember it.. )
“Auvi was designed with an attitude of sympathy towards beginners. Even now, Auvi can be a lot of fun for those who are less technically advanced — for example, those who don’t want to mess about with shaders and GL. I like to think of Max as a haven for artists whose needs aren’t met by standard software. Auvi was my attempt to increase the fun-factor for these newcomers.” Kurt Ralkse
Soccer Video Remixing
Because you need something to do with all those pipes, right? Recommendo : the 1981 Escape to Victory starring Sylvester Stallone, Michael Caine + Pele in a German prisoner of war camp. Or maybe? Pele’s viagara campaign, where he offers these last smiling words to the camera:
“Talk to your doctor, I would..”
An amusingly careful phrasing, which allows Pele to retain all suggestion of athletic virility, but let anyone else know – Pele says it’s ‘ok’.
Video routing software does exist, I think at least as a network-sending (and receiving) FreeFrame plugin.
Thanks for the Freeframe tip / comment, it’s probably quite useful on PC more than mac I’d be thinking.. how’s the Sydney pixel get togethers going?
