Morse code is a telecommunication encoding method that encodes text characters through sequences of signals (dots and dashes). Invented by Samuel Morse in the 1830s, it was one of the earliest digital communication codes.
Start at slow speed, memorize high-frequency characters (E, T, A, N, etc.) first, then gradually expand. The audio playback feature helps learn Morse code through auditory memory.
Supports A-Z letters (case-insensitive), digits 0-9, and common punctuation (period, comma, question mark, exclamation mark, etc.). Chinese characters are not directly supported. Letters are automatically converted to uppercase.
Morse code uses standard timing: dot (.) and dash (-) are separated by 1 time unit; characters are separated by 3 time units; words are separated by 7 time units. Audio playback follows these rules for clear signaling.
Click the 'Play' button to hear the Morse code audio signal. Use the speed slider to adjust playback speed (slow for learning, fast for practice). Note: the first play requires prior page interaction due to browser autoplay policy.
Recommended learning approach: 1) Start slow, memorize the sound of dots and dashes; 2) Learn high-frequency characters (E, T, A, N) first; 3) Practice regularly using the audio playback feature; 4) Start with simple words and gradually increase difficulty.
Besides audio playback, this tool provides a flash signal simulation that mimics Morse code light signals via screen flashing. You can also copy the Morse code result for use elsewhere or sharing.
