MacBook - Corona Version 2012.738 (2012.12.8)

Tested on iPhone, Simulator, Android. The "Simple Tuner" Example is a good example to recreate the bug. Tried with singing, guitar and sounds on my piano.

Issue: There is a delay on severel seconds before the tuner can read the correct frequency, it seems to wander with random readouts before it stabilize. This maked it unusable for guitar and piano and other sounds with shorter sustain.

If you compare with other tuners like "Cleartune" or "Peterson Strobosoft", there is an instant recognotion of the pitch
