Opening Titles for Web Directions South 2011

A Blue Perspective: <p>

See the in-browser opening titles

Another year and another great Web Directions. Of course, for me, Web Directions isn't complete without frantic late-night coding sessions in aid of completing a madly inspired conference-related project.

Last year I created the Web Directions 2010 opening titles in 3 days from start to finish. This year I gave myself a little more time but made it no less ambitious by expanding the production onto 2 screens; thereby requiring it to run on two laptops simultaneously. (And stay in sync!)

With the number of things that could fall over -- browsers crashing, projections being out of sync, people hating it -- my nerves were ringing right up until I hit "play". Luckily it came off without a hitch, and you can see the results in the video of the performance below. (Or if your computer's feeling adventurous you can check it out in your browser.)

Deep + Vocal + Bliss DJ Mix

A Blue Perspective: <p>

It's been a while since I did a house music DJ mix, so I thought I'd put together some tunes that I'm feeling at the start of 2013. This one starts off deep, goes vocal and ends on a blissful high, so take a listen, or download all 50 minutes as an MP3.


  1. Per Byhring - Ettertid (Russ Chimes Remix)
  2. Duke Dumont - Need U 100%
  3. Martyn - We Are You In The Future
  4. Bob Sinclar - I Feel for You (Ben Delay Dub Mix)
  5. Julio Bashmore - Au Seve
  6. Candi Station - Hallelujah Anyway (Larse Vocal Mix)
  7. Hot Chip - How Do You Do (Todd Terje Remix)
  8. Max Lyazgin & John Martin - Good Morning
  9. The Other Tribe - Sing With Your Feet (Instrumental)
  10. M83 - Midnight City (Sharam Jey Remix)
  11. Tensnake - Coma Cat (Stanton Warriors Re Bump)
  12. The Presets - Promises (Lifelike Remix)

Visualising <audio> elements with the Web Audio API

A Blue Perspective:   <p>

For a new project I'm working on I'd like to create an audio-reactive visualisation using analysis of the music that's playing. The new Web Audio API lets you do this pretty easily in the browser (Webkit-only at the moment).

I'm posting my documented code here with an explanation for anyone else who would like an easy snippet to get them started down the music visualisation path. You can view a demo here and download the source code here.

The main concept in the Web Audio API is that you wire up a bunch of modules together. The output from one module going into the input of another module. To this with an <audio> element, you have to create a Web Audio source with it, wire that up to an analyser, and then wire the analyser up to your speakers (so that you can hear the original <audio> again).

The code for all that looks something like this:

var audio = document.getElementById('music'); var audioContext = new webkitAudioContext(); analyser = audioContext.createAnalyser(); var source = audioContext.createMediaElementSource(audio); source.connect(analyser); analyser.connect(audioContext.destination);

Once you've done that, the analyser is now listening for any output from the <audio> and will have data waiting for you whenever you ask it.

Once you set the you can query the analyser at any time and check what the current frequency data of the sound is. If we put that analysis into a simple draw() loop then we can graph out what the sound looks like:

function draw() { // Setup the next frame of the drawing webkitRequestAnimationFrame(draw);  // Create a new array that we can copy the frequency data into var freqByteData = new Uint8Array(analyser.frequencyBinCount); // Copy the frequency data into our new array analyser.getByteFrequencyData(freqByteData);  // Clear the drawing display canvasContext.clearRect(0, 0, canvas.width, canvas.height);  // For each "bucket" in the frequency data, draw a line corresponding to its magnitude for (var i = 0; i < freqByteData.length; i++) { canvasContext.fillRect(i, canvas.height - freqByteData[i], 1, canvas.height); } }

You can see a demo of this running in my experiments section. I've just done a very simple line rendering of the frequency data but your imagination is the limit. Download the source code and see what you can do with it!

Stay tuned for the prettiness that I've actually got planned for this code.

Perfect Summer DJ Mix

A Blue Perspective:   <p>

Download the Perfect Summer DJ Mix (175MB)

It finally seems like Sydney's entered Summer. To commemorate the good weather and sunshine vibes, I thought I'd upload an old mix. Perfect Summer is designed for putting on as you drive to the beach or relax on the sand with a cool pina colada.

It's probably one of the last mixes that I did on turntables with all original vinyl, back in 2007. You can even hear the crackle of dust under the needle in the opening refrains of Solar Stone's Seven Cities.

Anyway, download Perfect Summer (or stream it) and get out in the sun while it's still here!


  1. Solar Stone - Seven Cities (Solaris Heights Mix)
  2. Kings Of Tomorrow - Finally (Rulers Of The Deep Mix)
  3. Orinoko - Island (Alternative Dub Mix)
  4. Graham & Blades - Funky Summa
  5. Plan B - #2
  6. Nalin & Kane - Beach Ball (DJ Icey's "The Sea" Mix)

  8. Orbital - Frenetic (12" Mix)
  9. Punks - Break Me With You
  10. Golan Globus - Blazer (Version 2)
  11. Maurice & Noble - Hoochie Coochie (Arcaic Mix)
  12. Chris Lake - Changes
  13. Underworld - Two Months Off
  14. Black Rock - Tiger

SlashGlobe: A 3D CSS experiment

A Blue Perspective: <p>

See the neon-spinny-3D-globe experiment

The third dimension isn't my strong suit; I'm fine with pixels but not with voxels. To start combatting this I thought I'd have a play around with the 3D CSS transforms that are available in the latest Webkit browsers (Chrome & Safari; sorry Firefox!)

What I set out to achieve was a neon-spinny-globe thing and I pretty much got there. I even managed to throw some Max Headroom aesthetic into the mix.

This experiment comes as-is, with all sorts of browser exclusions (and is best viewed in Chrome), so don't bug me if it doesn't work for you. Otherwise, enjoy the neon spinnyness.
