I stumbled across this thread today after trying to use AACalc online. Since I love the tool so much, I decided to try and make it work offline.
After some tinkering, I managed to put together a little app that runs AACalc on the client, rather than requiring a server; you can download it here: www25.zippyshare.com/v/58450275/file.html
Basically, I took the AACalc source files that djensen posted, paired them with an open-source “run PHP offline” solution called php-desktop, and voila! It seems to work well for me anyway. Just run aacalc.exe.
To djensen: I had to change one line of code in index.php, which was trying to include a file called load.php–but that file isn’t on GitHub. I’m assuming it’s not super important, since the tool seems to still work even though I removed the include. (if load.php really is important though, perhaps you could send me that file so I can properly include it in this release?)
To everyone: Enjoy! ZippyShare isn’t the best place to host something like this, so if someone wants to put the file in a better place feel free to take on the hosting part of this solution.
