ZebraTuner is a guitar tuner and generic
instrument tuner. It compares frequencies detected
in the signal coming from the microphone to
standard or user-defined notes, displaying the
results in both graphical and textual form. The
number of notes tested and their frequency is
configurable, so it can be used for other
instruments and other tunings besides those based
on equal temperament (e.g. just intonation-based
tunings).
