ToneTester 1.0

Mac application that tests hearing.

ToneTester is a Mac application that tests hearing. Specifically, it looks for offsets in how each of a person's ears hears pitch (the formal term for this is "binaural diplacusis" or "interaural pitch difference").

To use it, you adjust a slider until your ears hear the same pitch, and then ToneTester tells you the actual pitch difference. What's New
