051 – Minus


 
‘Minus’ is a piece I created for the seventh Disquiet Junto project. Here are the details:
 
“The seventh Junto project is a shared-sample project. Everyone will work from the same source audio, which is provided below. You will take the provided sound sample and from it make an original work. You will do this only by subtracting sound from the sample. You won’t add anything to it. You won’t slow it down. You won’t speed it up. You won’t cut it up, and you won’t otherwise reorganize its contents. You won’t play it backwards. You will only “remove.” The word “remove” is up for interpretation — but generally speaking, I’d say that it means various acts of lowering the volume of a narrow or wide band of the audio spectrum for either a short or long period of time. And, of course, “lowering the volume” can mean be interpreted to mean “muting.” The act here of “removing” is the sonic equivalent of sculpting something from a marble block.”
 
The source audio for this composition is a recording by Luftrum of waves crashing on the shore of Kalundborg Fjord at Røsnæs, Denmark: http://www.freesound.org/people/Luftrum/sounds/48412/
 
I created this piece by focusing in on four frequency bands – mainly lows, low mids, middle, and high frequencies. Each frequency band was processed in a slightly different way using the tremolo plugin in Logic Pro. The middle frequencies received the most attention. I automated the tremolo to vary the depth, rate, symmetry, and smoothing parameters. Also employed was a bitcrusher to down-sample the sound and degrade the quality. This was also automated throughout the piece.
 
The result is somewhat experimental. The artwork originally started as a picture of the ocean, but was processed using an iphone app called ‘Decim8′.
