Morse code represents text as sequences of dots (•) and dashes (—), originally developed for telegraph communication by Samuel Morse in the 1830s. Despite being nearly 200 years old, it remains an essential skill for amateur radio operators and is recognized as an intangible cultural heritage. This translator converts between text and International Morse Code with audio playback using the Web Audio API.
