Bidirectional Morse Signal Transceiver

International Morse Code is a historical telegraphy standard mapping alphabetic characters to sequences of short (dots) and long (dashes) electrical impulses.

This bidirectional converter translates alphanumeric characters to Morse code instantly, and supports full decoding from signal inputs. It features customizable delimiters and high-fidelity oscillator sound playback.

Core Tool Capabilities

  • Bidirectional Translation: Translate plain English to Morse dots and dashes, or decode raw Morse back into legible text.
  • Audio Synthesizer: Listen to standard 600Hz telegraph audio generated via the modern Web Audio API.
  • Visual Beacon Flasher: View synchronized signal flashes on your screen during playback to observe dot/dash pacing.
  • Custom Separators: Define custom divider signs for letters and words (defaults to spaces and slashes).

Frequently Asked Questions

What is standard Morse code timing?
A dash is exactly three times the duration of a dot. The silent gap between parts of the same letter is one dot, between letters is three dots, and between words is seven dots.
How do I decode Morse code?
Paste your dots and dashes into the converter. Ensure letters are separated by spaces and words are separated by forward slashes.
Can I play Morse code sound on mobile devices?
Yes. The tool leverages the standard HTML5 Web Audio API, which synthesizes audio frequencies inside modern mobile browser browsers on both iOS and Android.
What are the default separators?
By default, single spaces represent letter separations and forward slashes ('/') represent word boundaries for clear readability.
