visual-tuner is a simple program for tuning a guitar using an oscilloscope display.
It captures audio and displays a waveform with the horizontal scan frequency matching that of the tuned note.

When the string is tuned correctly, the display remains stationary, otherwise it drifts to a side depending whether the frequency is lower or higher than the one aimed for.

The application is written in C and uses the SDL library for display and audio capture.

Wow. That is pretty cool. Wish the CE had a microphone.

It's not for the CE, though. It runs on a PC.
