Tuner tool version 0.0.2

Hi friends,

This is a new version of my tuner tool project for Nokia 770. As you can see on the screenshoot I added a piano keyboard to generate reference tones.

I want to thanks people on IRC channel #gstreamer who helped me with this project. In particular to ensonic for their ideas about how solve some bugs.

Tuner tool for Nokia 770

This is a new tool for our versatile Nokia 770. I wrote this artifact mainly as an introductory mini project to GStreamer.

Basically it consists on a GStreamer plugin based on KISS FFT library to perform a fourier transform on a signal and extract fundamental frequency.

On top of the plugin I wrote this small GUI for Nokia 770 that build a GStreamer pipeline between microphone and gstkissfft component.

I'm spending holiday on the beach these days and I couldn't test it with a real instrument, any comment will be appreciated.
