A Free AAF Checker for Audio Post: Why We Built It
Every audio post project starts the same way. An AAF arrives from picture editorial, you import it into Pro Tools, and only then do you find out what you are actually dealing with. Sometimes it opens clean. Often it does not, and by the time you know, you have already spent the first stretch of the session sorting it out.
Today we are releasing a free tool that moves that moment earlier. Drop in an AAF and it tells you whether the file is sound before you import it. The check takes seconds, all locally. Compare that to opening Pro Tools and importing the file, which normally takes several minutes before you can dig through it and reach the same answer.
A broken AAF is never one person's problem
This is the part that made the tool worth building. A bad AAF does not cost one person half an hour. It costs the editor who exported it, the assistant who imports it, and the mixer who inherits whatever survived. Each handoff carries the problem forward, and each person down the chain pays for it again.
The check works in both directions. A picture editor can confirm an AAF is good before sending it, instead of finding out three handoffs later that something in the file was wrong and being pulled back into a fixing cycle. An audio professional can confirm what arrived is workable before committing time to it. The fewer broken files that move down the line, the better for everyone who touches the project.
That is also why we did not build this only for Pro Tools mixers. The AAF is the shared object across the whole post chain, so a tool that validates it is useful to anyone who hands one off or receives one.
Why it is free
A free tool does not make commercial sense on its own. We are doing it anyway, on purpose.
We built Forte AI to take the unpaid, invisible work out of audio post, and the cost of a broken AAF is exactly that kind of work. Giving the community a way to catch it early, for nothing, is the most direct version of what we are trying to do. We would rather put something genuinely useful in people's hands, and earn the word of mouth that comes with it, than gate a 30-second check behind a price.
The checker came out of building fPost, our session prep tool that turns the hours of manual AAF and PTX prep into minutes. Validating the file was one step inside that larger workflow, and it stood on its own well enough to hand out separately.
The AAF checker is free to download here. If you work with AAFs, try it on the next one that comes in. There is more on the full prep workflow on the fPost page, and if you want the background on why the handoff breaks so often, we wrote up the AAF session prep problem and put together a complete guide to the AAF format.
