It’s Just Noise!

As readers of my blog will know by now you can easily import any data into audacity and play it as audio. However, most data that you’ll import and then play will just turn out as noise. That is simply because there’s too much noise in the image i.e. too many colours and too much data. So, if you reduce the amount of colours and data in theory you get something a little bit more pleasing to the ear. Experimentationing time!

These were my initial two shapes that I worked with:

And the resulting sound, when looped a lil’ bit:

It’s not much but it shows definite potential. I’ve yet to work out how colour affects the sound, but I’m getting there

The next logical step is to of course run a glitched image through this process! I worked with this image for the sound then used ImageMagick to crop the image to 30x30px squares and used FFmpeg to arrange them into a video.

It’s noise, but I like it 🙂

GPS Sounds

Inspired by a lot of noise and randomness that I’ve listening to recently I converted Nikki‘s GPS Traces from her Uncertain Eastside project into sweet sweet noise!

Visualising BitJam

On Thursday 4th February I was Stoke-on-Trent for BitJam. I still don’t have anything ready to show on stage but thought I’d use the night as a testing ground for some of my ideas. I wanted to investigate ways in which to interpret what was happening around me. The main performance of the night was from a chap called Arctic Sunrise

For my first test I fired up Alchemy and attempted to draw the music. Alchemy fortunately has a few tools that can make your sketches react to sounds. They are Create > Mic Shapes and Affect > Mic Expand. Here’s the result of using both of them together

And a nice little animation of those done using GIMP and Openshot.

The next method was to use the Echobender script on a webcam pointing at the stage. Obvious errors in the sound recording actually kinda complimented the video. However, I’m a lil bit disappointed by the speed of the script at the moment. I may investigate doing something similar in Processing.

The final method involved a bit of post-processing. I made a short compilation of clips I shot at BitJam and then opened the video in a text editor and replaced loads of text with other text. The output was then reencoded using Avidemux

So, there you have it! Now to figure out how I can turn this into some sort of performance
