This app is sound FFT and frequency measure, that is Morse-code decoder "Valiance Backbone for CW (VBC)"'s subset.
So, if you had the VBC, you did not need this VBCTone.
VBCTone is useful to detect call-back DX stations frequency.
VBCTone is able to measured transceiver's CW pitch.
Frequency resolution is ±5Hz.
Preparing operation for FFT makes correct frequency and High resolution shape. Let's try it!
This app contains these functions like bellow.
tone zero-in/shift-in indicator / tone frequency measure(±5Hz) / sound level measure / peak search
Operation movies are in www.youtube.com.
