ProTools Session File format

Archived from groups: rec.audio.pro (More info?)

I'm looking for information on the detailed structure/format of a
ProTools session file. I'm trying to develop software that would take a
session, rip it apart and put it back together in a specific way. I do
audio post production and am trying to automate some of it.

Thanks for any information or suggestions.

I suspect that if this was easily obtained information, there would be
a lot of programs that could import and export ProTools session files.
It's "secrets" like this that keep DAW projects from being completely
transportable from one system to another.

I'm sure that you can do a certain amount of reverse engineering to
find out how chunks of audio are numbered and arranged in time, but
there's more to it than that.

Why don't you call Digidesign and ask for the documentation? <g>

Yes.. but here is the decryption code...

byte d = pBuffer[19] * 39;
byte s = pBuffer[19] * 29;
pBuffer[19] = 0;
for (DWORD i=20; i<dwSize; i++)
{
d += s;
pBuffer[i] ^= d;
}

Now someone has to kill you...
