App to determine exact musical pitch

[jon3825]

Is there an app where you can hold the Droid to a sound and it talls you the exact pitch in Hertz? Whether I sing to it or dog whistle to it or play piccolo to it or play a digital sound from my computer onto it?

what range of frequencies? I used gstrings guitar tuner for awhile and it did exactly that.

edit: this is what you want http://www.appbrain.com/app/org.hermit.audalyzer looks like a pretty basic spectrum analyzer. I have no idea about the built in microphone, but that probably limits you to audio frequencies (spoken voice) only with a very small bandwidth.
