## What is VBCTone?

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
