Re: [microsound] [ot] RGB freq?

[Bill Jarboe <billjarboe@xxxxxxxxxxxxx>]

hi, 

  I planned on staying out of this , then became curious about making red,
green and blue .bmp files , converting them to sound and playing them
together. Trying to work quickly I halved them timedomainwise in audiosculpt
and also tried generalized cross-synthesis on the colorfiles in
combination.I then wondered what yellow would sound like , would the
combination of blue and yellow have a different effect than the green file I
converted? etc.

  Inspiring results at any rate ,especially since the original
colorsoundfiles(.aiff) are extremely compact when stuffed.

 It then occurred to me this might be something to include in the
droplifting project...I don't know in what form . The compact .aifs for
remixes might be nice. I decided that silence could = black and noise= white
and made a 'sortawhite' file that sounds appropriate enough yet it's a
monster sizewise compared to the others (4mb stuffed).

 How are people coming along with the droplifting project?Is everyone aware
of the guidelines and intentions?

 I might upload what I have to the droplifting folder on the hotline server.
Does this seem like a fun idea to play around with? Am I robbing Phil to pay
'whoever'? Does anyone own the colors ? etc...

   have a nice , productive and ( if you live on the east coast of  north
america ) hopefully not too dark day.

                             Bill
