This is a JavaScript for After Effects I wrote. It does exactly what it says. The Audio to Keyframe function in After Effects is awesome and now you can convert it to Maya.
NOTE: One bug is already known: When you try the script for the first time after launching After Effects it somehow stops after the import. Easy solution: Run the script again and it works fine
NOTE: I haven't tested it on any other Maya version than 2012. It should work on older versions. Please use the contact sheet to let me know if there're any problems and I'll try to fix them.
