--> Folks, i'm developing an audio programming language to be ported for PDAs... I hope it can sound good as pd or csound, but - off course - this is just a dream by now.

If anyone here is interesed in the project, please contact me... (jpcyrino@gmail.com)

what PDAs? palm? what hardware? what OSs? something like csound on a palm would be wicked rad, i think.

i think one problem could be the OS. at least on WinCE (or however that is called at the moment) it's very hard to do time critical stuff, so i am told.
but nevertheless sounds interesting.
what kind of language are you thinking of? similar to what?

what do you mean sound good i wonder? those apps you mention, all of their dsp is dependent upon the input and the resolution the signal maintains through the processing and how hard the cpu has to work to do the maths.

an interesting idea though.. portable buffer shredding would be kinda cool.

With PDA I mean ARM based portable devices, as I'm always working with assemblers for ARM. By the moment I'm writing my own samples using assemblers, in other words, I write programs that generates the wave files according to the instructions i've wrote. As I have a bundle of algorithms done for various kinds of synthesis, I guess it will be possible to generate something like a programing language for doing sound synthesis.

implexgrace, with "sound good" i'm actually not meaning nothing with sound quality. I just want to have a good way to make sound synthesis as csound and pd does. The problem of csound running in PDA is the speed. It works with floating point and that decreases the processing speed a lot. I have written some algorithms using fixed point that work pretty well, I guess. Well, fixed point is like pd...

I guess it is so... Thanx for the comments...

You know, even if the sound is totally aliased, mono and 22khz, if there's an ok step sequencer in it and can export as midi, it'd be a great portable tool.

jogn, that's a good idea...

Thanx for all!

"

i do not agree. there are a lot of different ways to calculate oscillators for example. if you compare pd with reaktor for example there's a huge difference in sound quality.
