New in 1.3:
+ Display pulse width (for freq < 2.5KHz)
+ Automatic amplitude fits.
+ Frequency counter.
+ Lab tested w/ 60Hz to 20KHz sinusoid.

The inverse sawtooth waveform is generated by Fourier's series, so it can take long on older devices.
The signal can be used to test electronic circuits through the phone output.
CAUTION: playing very loud square or sawtooth signals can damage the device's speackers.
THANKS jjoe64 for the "graphview" graphing library!
Is easy to tune the instrument.
Various experiments with a wide band of frequencies is available.
Frequency setting: C, C #, D, D #, E, F, F #, G, G #, A, A #, B
Warning: This sound by the frequency of the sine wave is generated in real time. So the sound is very large.
(Not a wave file.)
Do not close your ears to the sound.
Required: Adobe Air
