Riot in London - ANS spectral synth live demo of photo Image converted into Sound


Published on 15 Mar 2017
In this video we see a photo loaded into the ANS spectral synthesiser and processed further into audible sound. An image like this one can be processed in the free GIMP graphics program first if you like, in order to get the best effect out of the ANS. If an image is white, or bright, then ANS will see this as sort of transparent and will allow light throughout the image, hence nearly all tones will sound and it will come out as white noise or similar. There are over 700 tones in ANS, so that is a lot of sound coming out at once, hence the white noise effect. But by creating a black "ink" background in an image or transparent alpha etc. and making the image appear as an "etching", this will enhance the sound a lot. This sound was was then routed into the audio input of the Roland MC909 where the sound can be played up and down the scale using the MC909 pads or the MIDI connected keyboard. A tool brush was also crudely made from the image in ANS by selecting a portion of the image and making a brush tool. This was used to draw an image in another new project. A midi keyboard can be used to play and draw notes in the ANS. There was a problem with that particular method when I used it, probably down to me needing re configure my MIDI set up with the ANS better. But for audio in on the MC909, no problems.
