enable Guitar Tuner performs real-time tuning for a
range of instruments, as well as presets for each instrument in a variety of
styles. You can transpose, use common jazz and orchestra references or even
enter your own custom frequencies for unlimited flexibility. enable Guitar
Tuner automatically determines your instrument / string's current frequency
to high accuracy, and tells you the corresponding musical note. Use the
transposition facilities to aid you in writing music or transcribing pieces
you don't have sheet music for. Learn to "tune by ear" using the Play Tone
feature, which generates the note you are trying to play while you tune to
it.
