8月22日 的 Valiance Backbone for CW - VBC 應用程式分析

Morse Decoder: Valiance Backbone for CW (VBC) VBC is the No. 1 Morse code decoder in the Japanese market, encompassing both paid and free categories. This app allows you to decode Morse code using the built-in microphone of your iPhone or iPod touch. VBC utilizes the world's fastest FFT (Fast Fourier Transform) technology to detect and decode carriers. It is specifically designed to minimize false decodes from atmospheric noise, voices, or beep sounds (square or trapezoidal waves). While it will not decode vocalized "dit-dah" sounds, it offers an extremely high success rate for decoding actual transceiver signals. (Please check our videos of real DX station communications). We believe its decoding capability surpasses that of many expensive dedicated hardware units and PC software. The carrier detection mode is highly effective, making it a truly practical tool for active hunting and pouncing in real-world radio operations. The default settings are optimized for the best performance balance. We recommend testing it with an actual radio (800Hz tone) at a short distance using the default configuration. Key Features: Morse Sound Recorder & Player Export text logs, audio data, and history via email Timestamp and cancel stamp insertion in logs Predictive decoding for difficult or connected Morse codes Zero-in Tone Indicator / Shift-in Indicator Tone frequency measurement (±5Hz) Sound pressure measurement (dB) Audio frequency response measurement & automatic correction Peak search / Manual frequency setting (double-tap screen) Automatic speed tracking / Manual speed setting (double-tap screen) Auto Level / Auto Threshold / Manual Threshold (double-tap screen) Noise reduction & waveform shaping via carrier detection Japanese (Wabun) Morse support Signal level adjustment Input Level Over-Range Indicator When the input level exceeds the range (Over-Range), the waveform becomes distorted, leading to poor decoding accuracy. If this happens, please move your device further away from the radio. (Avoid placing the device directly on a vibrating radio; maintain a sufficient distance. The app is designed to decode accurately even from a significant distance.)Supports decoding speeds from 5 to 40 WPM For more information and to see the app in action, please visit our YouTube channel for Real-DX videos and more: http://goo.gl/ALXAqH http://goo.gl/yEu3d1 http://goo.gl/7gp4yw Note: Due to scrolling issues on the decode screen since iOS 8, we utilize the following library for text display.
