Turn text into Morse and play it with Web Audio tones — adjustable pitch (Hz) and speed (WPM), live highlight, WAV download.
Type text and click Play to hear it in Morse. Use the Tone slider to set the pitch (default 700 Hz, the classic CW tone) and the Speed slider for words-per-minute (PARIS standard). The visualizer lights up each dit / dah in real time. Encode turns text → Morse, Decode does the reverse. Download WAV renders the current Morse to a downloadable 16-bit PCM file. Everything runs locally via the Web Audio API.
