Waht is this program ?
This is oa, a toy I needed to experiment with some wave-forms. I was trying to produce some "ooo" and "aaa" sound, like what do some guitarists with some pedals, so I made this program to help me doing this.
I like it so much I decided to release it ! even if it is only a toy.
It works with Linux (for the sound) and X-Window (for the interface).
You need a C compiler to build it (but I guess you have a gcc version somewhere on your host, or you are not a real linux-user !).
Yes, the window is very big (1024x868), yes I know, don't blame me. It was the size I needed.
Where to get it ?
Well, I guess you have it ! because you read this file.
The original url it can be found on is : http://sed.free.fr/oa/index.html
How to build it ?
Go read the file INSTALL that should have come with this one.
How to use it ?
You can use it very quickly, I think the interface is obvious.
Try to have some wave-forms that will procude realistic "ooo" and "aaa" and send the oa data files to me !
You even can save what you do to a wav file. If you produce one, put it somewhere I could download it and send me a mail (sed@free.fr). You can do crazy things, really, like some people do with their wonderful "electro-acoustical music".
What is a wave form ?
A wave form is the smallest part of a musical sound. You surely know that a musical sound is a succession of sin-waves, those sin-waves changing in the time in many ways, producing the music (or the voice, by the way). Well, here, you can design your own wave-forms and see what result is produced.
We are far from the reality of an instrument, where other parameters exist, like the sound attack (at the very beginning of a note, the instrument reacts in a special way, getting to its stability point, and with the voice it's even worse), or sound intensity, or some subtle variations of frequencies, or some noise (like whispers in human voices, that are very important I think, to understand the nature of the voice), and so on, and so on... (Well, I am not a specialist of the stuff, but I think I don't say too stupid things, do I ?)
But I think we can have some fun with this toy, even with those restrictions.
Enjoy.
