The Microsoft Agent Character Editor (Ace or MACE for short) is a program made by Microsoft to allow users to edit and compile their own Microsoft Agent character. It was first confirmed to appear in the Microsoft Agent Beta 2.0 and Microsoft Agent 1.3 and has had a release for every public Microsoft Agent version since. It allows users to create new characters with all the major technologies of the platform, including text-to-speech, animation states and lip-syncing. The user can add animations to their character from static BMP or GIF frames; they can also add sounds to the animation or assign the state that triggers the animation, such as the state "GesturingUp" triggering the animation "GestureUp" or add small mouth bitmaps to allow for lip-sync of their character's speech. Ace saves character definitions as ACD files and builds the finished characters as ACS files.

Modern usage

Ace is now used to make most, if not all new Microsoft Agent characters. Most modern characters do not have much animations and rarely use much of Ace's features; lip-sync was a notable example of this before Konnor88 brought it back into popularity. Due to the way the tool was made, a lot of modern character animations have only one frame and a sound. Konnor88 has also made a custom version of the program called the Frontier Agent Character Editor.
