AeroTuner Guitar Tuner - Digital Strobe Tuner
Version 0.9.3		2003-Dec-05

For PalmOS 5 models which include sound manager support and
an internal microphone:
  Palm Tungsten T, T2, T3
or:
  Palm Tungsten C with an external microphone plugged-in.

The AeroTuner Guitar Tuner includes a high quality strobe tuner in
addition to 6 individual match needle indicators, one for each string
(E A D G B E), with both a frequency readout and cents offset
readouts.  The options dialog will allow you to modify your center
tuning frequency for A = 440 from -4 to +5 Hz.

Pluck an open string on your guitar near the Tungsten microphone and
this application will try and tell you which string you are playing,
the frequency of the musical note, and how close it is to being in
tune.  If the string indicator turns green, the strobe display at the
bottom will stop moving when you are exactly in tune (within 1 cent,
better than +- 0.1%).

The strobe window displays the tone being played synchronized with a
perfect pitch window.  If the frequency is close to correct and moving
left, then it is slightly flat.  If it is moving right, then it is
slightly sharp.  The slower the bars move, the closer the mic input is
to being exactly in tune.  Please note that if the frequency of the
guitar string or sound input is way off, then you may get the movie
"wagon wheel" effect, where it seems to flicker in the wrong direction;
so make sure the needle indicator is close before using the strobe
tuning window.

Because the microphone on the Tungsten T is a voice mic and not a music
mic, the positioning of the microphone is very important.  This mic is
in the upper left edge of a Tungsten T.  Try holding the Palm handheld
about a foot in front of your guitar's sound hole, and/or place the
handheld on a soft surface near the front of the guitar.  Pluck the
string near the center (at the 12th fret) for the cleanest fundamental
tone.  Make sure to let the other strings stop vibrating first.

*** UP/DOWN buttonw for Single Note Tuning ***

If the Guitar Tuner is still having trouble determining which string
is being played, use the up/down scroll buttons or the pop-up list
selector to select single string mode.  There is also a pop-up list
that will allow you to tune one of the harmonics (overtones) of the
string, if the fundamental note is too hard to detect.  

The Guitar Tuner application turns off after 5 minutes to conserve your
Palm handheld's battery life.  To turn the application display back on
or to reset the 5 minute timer, press the Address-List button below the
display.  Press this button twice is you want to exit the Guitar Tuner
and go to the application normally launched by this button.

In single-string mode you can also use sideway presses of the 5-way
navigator to adjust the tuners per-string cents offset, for tuning
to special temperaments.  The options dialog allows you to view
and change your cents offsets.  Use +0 cents for standard 12-tone
equal temperament tuning.  Some people think that tuning the low
E string at around -3 cents sounds "sweeter".

This is a new application.  User reports are very welcome.
