【實用工具app】VBCTone|最夯免費app-綠色工廠好玩App

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 searchOperation movies are in www.youtube.com.http://goo.gl/yEu3d1http://goo.gl/7gp4yw
