Frequently Asked Questions

What is Morse code?
Morse code is an internationally standardized telecommunication method (ITU-R M.1677-1) that encodes text characters as sequences of two distinct signal durations: dots (short signals, called "dits") and dashes (long signals, called "dahs").
How does audio timing work in Morse code?
Standard Morse code audio adheres to the Paris timing standard: a dash is exactly three times the duration of a dot. The silence between dots and dashes in the same letter equals one dot, between letters equals three dots, and between words equals seven dots.
Can I play Morse code sound directly in my browser?
Yes! Our tool synthesizes crystal-clear audio tones in real-time using the Web Audio API without downloading external audio files. You can adjust the playback speed (WPM) and audio frequency.
Is any of my text sent to a server?
No. 100% of translation, decoding, and audio synthesis runs directly on your device via client-side JavaScript. No data is transmitted across the internet.
