Santa brought me a wonderful little Kodak Zi6 HD video camera this year. I spent a couple hours on a meditative down tempo track just to inspire me to create a short film. I have no name for the young audio piece but I do have a fragment of it to share. I was experimenting with the macro setting and got some nice lens flare action.

Today’s fascinating sound is another example of the conversion of digital imagery into sound and was submitted by Manchester based artist Nick Froud. Nick writes:
“I have been following your blog for months and have found it really inspiring. The software featured in your most recent entry is quite similar to a program I (very quickly) put together for an exhibition idea I have. My girlfriend produces photography based and nature and process, I wanted to adopt these ideas into sound that could accompany each of her pictures in a gallery.
The program I made converts an image directly into sound by scanning along each pixel and outputting a sample to a wave file based on an average of the red, green and blue channels. It also outputs the red green and blue channels as CC data in a MIDI file. In this way, I intend to create music entirely generated from an image but with human direction as to choices of effects to be controlled by MIDI data, layering of sounds etc. The sound generated are much noisier than in other sound / image conversion applications, but I think it gives a better feel of the texture of an image.”
You can hear more of Nick’s creations on his myspace sites Crunchy Alligator and Circastate.

Here’s a short little bass line I recorded while reacquainting myself with my Maxi-Korg yesterday. I love the gritty sound of this instrument, one of the most well known of the duophonic synthesizers. Sometimes I find myself reaching for the non-existent pitch or modulation wheels, but the limitations of these vintage devices are part of their charm and might encourage the musician to come up with new ways to play (or rediscover old ways).
Another thing that I love about vintage gear is the lack of presets. When I come up with a sound I like I simply say to myself, “you’re never going to get exactly that sound ever again”. You can always jot down the settings, but I never do. This way you’re forced to learn how to control the device and approximate the sounds that you have created in the past if necessary.

I literally dusted off my Maxi-Korg today which had been stored in a closet for well too long. To my surprise after a minimal amount of wiping and moving the controls it still sounded as clean as the last time I used it. This synth really sucks you in. After spending a couple of hours creating sounds I decided to experiment with the repeat function.
The repeat function has two sliders; one for speed and the other for the duration or width of the note repeating. It also has a mode switch. I set the mode to “A” to retrigger the note I was playing, then fussed with the speed and width to get this wet, growling, engine like noise. For the time being, I’m leaving this beast in my studio so expect to hear more from the Maxi-Korg in the future.

Recently I was invited by Michel Rouzic to try his software, Photosounder, designed for converting images into sound. Image to sound conversion is something I’ve been meaning to explore, so today I finally had some time to have a look. The software does much more than create strange sound from images. It’s a great time stretching tool, and it also reads in wave files as images allowing you to use the same sort of manipulation you can do on image based files.
This sound was created from the full resolution version of the graffiti photo shown. I settled on this image because of it’s simplicity, and the diagonal strokes of the tag produced a nice cascade of descending pitches. The way the flash lights up the center of the photo gave the sound a dynamic swell that I emphasized by adjusting the gamma parameter. Photosounder allows you to set the time and frequency range of the audio produced, so for this example I put the bottom at 52Hz and the top at 12kHz.
