叫ぶモールス信号 vs CW Decoder

日本語（ひらがな、カタカナ、アルファベット、数字）を入力して変換ボタンを押すことで日本語（ひらがな、カタカナ、アルファベット、数字）をモールス信号に変換することができます。変換したモールス信号をホイッスル音やさまざまなボイスで再生することができます。またiPhoneに搭載されているカメラ横のLEDライトをモールス信号に合わせて光らせることも可能です。モールス信号から日本語への変換も行えます。

High-Precision Morse Code Decoder（AI greatly improved the decoding rate!） 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.
