Convert text cleanly to Morse code or decode Morse code back into English in real-time. This tool features a built-in synthesizer utilizing the browser's native Web Audio API to play back your Morse code as standard audio beeps (dots and dashes) instantly.
Key Features of Morse Code Converter
- Bi-Directional Translations Translate normal English sentences to standard Morse code, or parse dot-dash inputs back to plain text.
- High-Fidelity Audio Synthesizer Listen to Morse beeps in real-time, generated locally inside your browser's audio stream.
- Tempo Calibration Sliders Adjust transmission speeds dynamically from slow training patterns to master speed beeps.
- Custom Spacing Parameters Configure visual separators for words and letters (e.g. forward slashes) to organize layout outputs.

The Technical Details
The Morse Code Translator implements standard ITU-R M.1677-1 definitions inside an offline JS map module. Character keys are matched against their standard dots-and-dashes arrays.
For audio synthesis, it leverages the browser’s hardware-accelerated AudioContext class. It compiles oscillator nodes with custom gain filters on the fly. Playback beeps are scheduled as precise millisecond timeline envelopes (where the duration of a dash is exactly three times a dot’s length), preventing browser execution lag.
Frequently Asked Questions
Which characters are supported?
The tool supports all Latin letters (A-Z), digits (0-9), and common punctuation marks including period, comma, question mark, and more.
Can I control the audio speed?
Yes. A speed slider lets you adjust the playback tempo from slow practice speed to full transmission speed.
Is any data sent to a server?
No. Conversion and audio playback run in your browser.
Is this standard international Morse code?
Yes. The tool uses ITU standard international Morse code as defined in the international radiotelecommunication conventions.
