Real Web Audio Playback

The Play Audio button generates genuine 700 Hz oscillator tones via the Web Audio API, timed to real Morse standard ratios: a dah is 3× the length of a dit, with proportional gaps between symbols, letters, and words.

International Morse Code

This is the real ITU standard Morse alphabet, still used today in amateur radio and aviation as a low-bandwidth, high-noise-immunity signaling method.
