hey chuckk,
given the picture, no wonder it sounds bad ;-)
i have actually not used this object myself (i use it's inverse) so not much help - maybe IOhannes or someone will know more, or there's the source code...
good luck, p

Here's what I have so far, using: http://upload.wikimedia.org/wikipedia/en/d/df/US_%241_obverse.jpg Since it's not copyrighted. I don't understand exactly what's happening. It doesn't sound to me like it's what I want; the frequencies just don't seem to line up.

So, it seems to me the input would have to be a couple of pixels at
a
time, with a small block size, in order to scroll. Like enter a column of pixels and do, as someone mentioned, reverse FFT to get a block. Maybe map the image to a rectangle with width 1, then slide
it
across? I don't necessarily have to see the scrolling or even the image, but it would be nice. I don't want to be obnoxious, but I know next to nothing about Gem,
so
any suggestions are welcome.

That looks rad. I'll have to try it out.

Like this?
Yeah, I think so. How's it work? Thanks for sharing.

Not sure exactly, it's not my patch, but from the screenshot it
looks
like it copies a scanline of greyscale pixels into an array,
then
rescales the array exponentially into annother array
(frequency<->pitch
conversion), then does an inverse fft and sends the resulting
audio to
dac~; the partials of the output sound being determined by the particular scanline of the image that was just copied to the
array.
I think this technique is a form of "scanned synthesis", but I'm
not an
expert on terminology. At least searching pd-list for that term
shows
up some interesting results...

Yeah, it's one of my more violent pieces.

Thanks. I'd like to include something like this in my senior recital in March, so if I figure it out now I'll have 2 months to try different bitmaps.
