After finding Suitable Systems ToneTester for Mac from EasyEarTraining via reddit, I noticed the binary was PPC only, and my macbook wanted to install Rosetta. Well, thanks to the foresight of Daniel Griscom, I was able to download his source code and compile it to run on i386. This was built with a target of 10.5 release and required no alterations to the code, although it did have one warning, AudioDeviceAddIOProc is depreciated.

I threw the original PPC build into the DMG along with the new x86 build. Go ahead and download ToneTester UB for your intel based mac.
