Description:
QPitch is a program to tune a musical instrument using your computer and its microphone or line-in input. It is designed to be completely cross-platform and works on Linux, Mac and Windows platforms.

QPitch 1.0.1 is an offspring of K3Guitune 1.0. The layout of the GUI and the pitch detection algorithm are quite similar to the original ones, however the application has been rewritten almost from scratch to take advantage of the new features of Qt4 and to use the cross-platform PortAudio library. The FFT is performed using the FFTW library.

The pitch detection algorithm is based on finding the first peak in the autocorrelation of the input signal. The method is quite reliable (even if a peak may also occur at sub-harmonics or harmonics leading to an erroneous pitch detection). The fundamental frequency used as a reference for pitch detection can be configured according to the user preferences.

The estimated pitch is displayed on a note scale graphic, while the input signal and the autocorrelation function are displayed using an oscilloscope-like plot.

1.0.2 (ie current svn version) now detects and displays the octave number of the note you are playing which was the major missing feature in 1.0.1 hence Linux finally has a fully-functional, easy to use instrument tuner. I can stop using APTuner under wine now and I'm keen to see qpitch make its way into the 'buntu repos.
