Mirror sound/Sound mirror – 2

Posted in quotes and advices, Sound Art, Theory, Transmedia Research by tpdr on December 26, 2009

Reflecting a bit more on this topic and while doing some tutorials learning about music/sound and Pure Data, I had an interesting thought about ‘noise'(well for me it was interesting because thinking about sound is quiet new for me…maybe for the more specialized people when it comes to music this is a quiet dull post…).

Apparently Claude Debussy composed as follows: ‘I take all the chords and leave out those I don’t like…’ You could say that he thus, when we make a parallel with digital sound, he would have taken ‘noise’ and filtered out all the frequencies he didn’t like. This was exactly the way I was thinking about starting to work with sound for 2 reasons.

1) If you take a look at my video of my first experiment with light and sound and the see-thru-mirror foil, it has a sort of filtering aspect.

2) My interest for mapping and cartography take  into account, filtering is something I constantely have to do (even as a ‘regular’ graphic designer). Especially doing mapping and creating any kind of map (even a personal/subjective map) is actually try to filter out all the information/data one doesn’t need in relation to the theme of the map or the needs of the creator (if one is creating his/her own map).

For these two reasons starting from ‘noise’ and try to filter out certain frequencies would make working with sound more intuitive, natural, … especially since I am making a certain shift now coming from a more visually oriented background.

Then again this doesn’t solve my question yet when thinking about the auditive equivalent of mirroring and transparency. If we start again from ‘noise’ we could say as it contains all possible frequencies, it is actually very similar to white light. So if we would take this to the level of transparent objects, these would not change the light so much except maybe for ‘breaking’ the waves up revealing the full spectrum, like a prism. Corresponding to this on a sonic level we could say a transparent object, filter would let all frequencies pass through, resulting in noise in front of and behind the object (an ‘audio prism’ would then be an object that would break up the noise into all frequencies in a way that these are revealed/separated). A ‘transparent object’ when talking about sound wouldn’t necessarily need to be a ‘visually transparent object’. A simple example would be to say that some kind of textile that doens’t let any light/visual data pass could very well let all the noise pass through while a very thick glass window could be visually transparent but block all sounds at the same time. (Here we could also discuss the fact that sounds can auditively connect spaces which are visually separated and certain materials can keep a visual connection between spaces intact while separating them on the auditive level. But that might be all discussed in a following post.).

Similar to this we could say the same thing for reflecting light(visual data) and sounds(audio data). Some surfaces will reflect light, others will reflect sound waves. Some materials will reflect both light and sound, some only one of these two.

Discussing objects to be transparent/reflectors or not on the visual and the sonic level, is interesting and will probably be useful too, but it doesn’t yet help to define ‘transparent sound’ or ‘mirror sound’ in an interesting way yet. Lets keep this for a 3rd post.
