Morse Code Generator

Morse Code Generator: Core Features and Principles

Want to intuitively understand or listen to the "dits and dahs" of Morse code? This tool converts your input text into standard Morse code symbol sequences and playable audio in real-time. Morse code is an on-off signal encoding system that uses different combinations of short sounds (dots ·) and long sounds (dashes -) to represent letters, numbers, and punctuation marks. The tool is built on the International Telecommunication Union ITU-R M.1677-1 standard, while allowing customization of various audio parameters to suit different scenarios.

Why Choose Our Morse Code Generator?

• Supports 7 professional parameter adjustments: Including sample rate (8000-192000Hz), dot/dash duration, symbol spacing, frequency (100-5000Hz), and volume, meeting teaching, experimental, and communication needs.
• Real-time playable audio generation: The conversion simultaneously produces a standard WAV format audio stream, supporting online playback and download.
• Built-in 1-click SOS emergency signal generation: A dedicated button to quickly input the internationally recognized distress signal ···---···.

Tool Tutorial

1. Type the text you want to convert into the input box (e.g., Hello World).
2. Adjust parameters such as sample rate, dot duration (0.01-5 seconds), and dash duration (0.01-5 seconds).
3. Click the "Generate" button to get the Morse symbol sequence and audio player.
4. Use the playback controls to listen to or download the generated audio file.

Frequently Asked Questions (FAQ)

What characters does the Morse Code Generator support?
It supports the standard ASCII character set, including letters A-Z (case-insensitive), numbers 0-9, and common punctuation. Non-standard characters will be automatically filtered out.

What format is the generated audio file?
The output is a browser-compatible WAV format audio stream with an adjustable sample rate (default 44.1kHz), supporting direct playback and download on all modern browsers.

Important Notes

It is recommended to keep the input text length under 1,000 characters to ensure generation efficiency; special characters may be replaced with spaces; high-frequency (>4000Hz) settings may cause playback distortion due to device differences.

Pro Technical Notes / Usage Suggestions

For educational purposes, it is recommended to maintain the standard ratio of dash duration = dot duration × 3, character spacing = dot duration × 3, and word spacing = dot duration × 7. Typical example: The SOS signal "···---···" corresponds to an audio of three 100ms short sounds + three 300ms long sounds + 100ms symbol spacing, totaling 1900ms in duration.
