How it works
Each letter maps to a unique sequence of dots and dashes in International Morse code. A dash is three times the length of a dot; letters are separated by a gap of three dots, words by seven. Decoding reverses the lookup. The player schedules real beeps with the Web Audio API at the speed you choose — nothing is recorded or uploaded.
