MorseFriends vs CW Decoder

・アマチュア無線で電信を楽しみたい友達へ贈るアプリです。 ・モールス信号を聴き取る練習ができます。 ・設定機能によりバックグランド 再生や符号の文字間延長秒数の設定ができます。 ・モールス信号を正しく打つための練習ができます。 ・モールスの信号音から簡易な解析により文字に変換することができます。 　※ 解析方法が簡易の為、正しく変換できる確率が低いです。（残念） ・画面に合わせた使い方を表示することができます。

High-Precision Morse Code Decoder Achieve noise-resistant, accurate Morse code decoding with high-precision, sample-level signal processing. Try the superior “listening performance” in the free version. Differences Between Free and Full Versions This app lets everyone try the high-performance decoding engine for free. Free Version - Continuous decoding: Up to 3 minutes per session (restart anytime, unlimited times) - Basic font display Ideal for testing performance and checking short communications. Full Version (Paid Add-on) - Unlimited time: For long ragchews and continuous monitoring - Font settings: Customize font type and size for better visibility Recommended for active operation and a stress-free learning experience. Main Features & Technology High-Precision Real-Time Decoding - Speed range: 5–50 WPM (auto-adjust speed and threshold) - Frequency detection: 400–900 Hz (automatically tracks the strongest signal) Advanced Signal Processing - Bandpass filter: Narrowband filtering reduces unwanted noise - AGC (Automatic Gain Control): Compensates for signal level changes and fading - Noise blanker: Reduces spike noise using MAD (Median Absolute Deviation) - Signal stabilization: Multi-sample buffering helps prevent false detections Designed for Real-World Use - Scrollable text: Review and check missed content - Frequency lock: Tracks the actual operating frequency range (400–900 Hz) - Visual support: On-screen text supports listening and copying Recommended For Morse Code Beginners Great for those getting started with Morse code. Seeing decoded text while listening helps self-correction and improves learning efficiency. Amateur Radio Operators - CW practice: Compare results with your own copying to find weak points - Contests: Helpful for high-speed reception support and log checking - Portable ops: No PC needed—build a CW reception setup with just a smartphone Comeback Hams & Experts Useful for reducing fatigue during long monitoring sessions and supporting operators with hearing decline. Powerful filtering helps decoding in weak-signal or interference conditions. Note: Microphone permission is used only for signal analysis. No audio is saved or transmitted.
