okay, i think i have a better idea now of what you are going for. i can't really offer a quick solution, but it will likely involve programming. I think you're better off trying to start with a web cam or something like that as an input device. I know that processing has libraries for accessing camera devices, I'm sure Pd probably does too... then its a matter of mapping graphical data to sound.
it seems like the software you're looking at, arss amd enscribe are mapping visual data to audio frequency data. each one probably uses a different technique and method of mapping to get the sounds out of an image. here's what enscribe does: The scanlines of the input image are converted into frequency components and > then using an inverse Fast Fourier Transform, are converted into sound. The > left side of the image is the low frequency end, and the right is the high > end, up to just under the Nyquist limit if you want it. > there's a whole world out there of people doing this kind of stuff, I just found this: I think any discussion of "transcoding" image (or other data) into sound has to take into account that such mapping is purely subjective. The artistry is in finding meaningful transpositions from one medium to another. Using "raw" data as sample values is certainly one way, and using an image as spectrographic values for resynthesis is certainly another. There are certainly enough softwares out there that do either trick, and those sounds are familiar to us from the many many artists who have used those softs already (to death in some cases). Dig a little deeper and decide for yourself the relationship of pixel to sample instead of relying on other people's ready-mades and you might be on to something new. Basically, any image source used as a sound source is a matter of deciding how the data gets mapped. A good place to start would probably be for you to design a mapping method for static images that makes sounds you like, and then explore various images and patterns that produce sound. you could likely do this in Pd, but i'm not familiar enough with it to know how. I know in the old days people used to 'animate' sound. Films had the audio soundtrack actually printed on them as a waveform and a photo sensor would read that data to reproduce audio electronically. Some animators started drawing their own patterns of light and dark in order to synthesize sound directly onto film. I don't want to discourage your idea, i do think it is an interesting one... i'm imagining a scanner that you can set different images on to get different sounds, or control the speed and light sensitivity as you said... it could be pretty neat. but i think it might be an uphill battle, and there's probably other ways you could put your graphical background to work making digital sound. -grant 2010/11/12 João Mário <[email protected]> > On Thu, 11 Nov 2010 18:50:26 -0600 > grant centauri <[email protected]> wrote: > > > i imagine what you really want to do is be able to somehow map data > > coming in from the scanner to some sort of musical or more > > interesting sound. use scanner data as control data for some audio > > generator. > > > > i'm not sure how you'd manage that... i'm guessing it is possible > > with some level of programming knowledge. > > > > if that is the case let me know, then we can maybe attack this at a > > different angle. > > > > On Thu, Nov 11, 2010 at 6:23 PM, grant centauri <[email protected]> > > wrote: > > > > > cat simply dumps the output of one thing into the standard output. > > > if you type cat readme.txt you'll get the whole text of the readme > > > file pumped out into your terminal screen. if you do cat mysong.mp3 > > > you'll get a bunch of gobbledygook flooding your terminal. > > > > > > /dev/dsp is the device name of your sound card. so if you cat the > > > contents of a file or the output of another device you can use the > > > redirect command, > > > >, to send that output to /dev/dsp and you'll likely hear something. > > > > > > for example i just did this command: > > > > > > sudo cat audio/HumanAfterAll.wav > /dev/dsp > > > > > > and i'm now listening to a sort of ringing noisy mess. > > > > > > doing: > > > > > > sudo cat Desktop/americas_logo.png > /dev/dsp > > > > > > gave me like 15 seconds of whitish noise. > > > > > > if your scanner is a usb scanner, you can find out what device it > > > is by plugging it in and running this command in a terminal: > > > > > > dmesg | tail > > > > > > I just did it with a wireless mouse device and got this info: > > > > > > [17792.582043] usb 3-2: new low speed USB device using uhci_hcd and > > > address 2 > > > [17792.746260] usb 3-2: configuration #1 chosen from 1 choice > > > [17792.781655] input: Wireless Mouse Wireless Mouse as > > > /devices/pci0000:00/0000:00:10.1/usb3/3-2/3-2:1.0/input/input6 > > > [17792.781866] generic-usb 0003:05FE:0011.0002: input,hidraw1: USB > > > HID v1.10 Mouse [Wireless Mouse Wireless Mouse] on > > > usb-0000:00:10.1-2/input0 > > > > > > i searched around my /dev directory and found this: > > > > > > /dev/bus/usb/003/002 > > > > > > I take that as usb3-2 > > > > > > your machine might be different, but the usb scanner should come up > > > as a device somewhere in /dev/bus/usb > > > > > > so then you could have a terminal open, run the cat command and then > > > control your scanner with whatever software you have on your > > > computer to scan images or something like that. > > > > > > its not very elegant, but you might get some noise out of it. > > > > > > 2010/11/11 João Mário <[email protected]> > > > > > > On Thu, 11 Nov 2010 23:45:13 +0000 > > >> Rob Myers <[email protected]> wrote: > > >> > > >> > On 11/11/2010 11:29 PM, esphera wrote: > > >> > > > > >> > > Just wondering that you might understand me wrong the previous > > >> > > post.
