tuneit is a simple command-line instrument tuner for Linux.

It uses two different algorithms for pitch detection. By default, a simple and fast Schmitt Trigger based algorithm is used to detect the fundamental frequency of an instrument.

For better and more reliable results, there is an alternative FFT based algorithm which is much more CPU intensive.

As audio capture backends ALSA and JACK are supported. By default, tuneit will try to use the hw:0,0 ALSA device.

Options:

tuneit [OPTIONS...] [captureDevice]

Valid options:

-f Use the more CPU intensive FFT based algorithm
-i List available input ports and exit
-j Use JACK as the audio transport system
-l LATENCY Measurement window size in 1/N seconds (default is 10)
-r RATE Set desired ALSA sample rate (default is 48000)
-t HERTZ Tune the A note of the scale (default is 440.0)

What's New in This Release:
Now uses the floating-point version of FFTW3 and in-place transforms for better performance when using the FFT algorithm.
Fixes to support compilation with GCC 4.0.
