TI-TUNER v1.00

0. About

This program is able to calculate the sound of frequency using TI-83 Plus with the CBL/CBL2 and the microphone. It can display sound of pitch with a keyboard, lower and higher pitch name. Also it can play the sound by calculated frequency using the CBL2 and display a collected data and a near function. These functions are useful for educational use, I think. This program was announced on 8th meeting of T^3 Japan in 2004.

1. Installation
