Tools and code references

Choose by the job you need to do. Each card identifies an interactive tool or a reference and describes its actual inputs.

Reference with historical playback

American Morse

Compare internal gaps and long marks; open the main tool in American mode to convert typed text.

Technical guide

Audio decoding

Follow tone intervals into letters and troubleshoot a recording. This page does not upload or automatically decode files.

Two-way converter

Binary, hex and Base64

Encode text as UTF-8 bytes or decode valid binary, hexadecimal and Base64. Decimal, octal and Morse are not input formats.

Kana reference

Japanese Wabun

Look up 48 kana and voicing marks with worked signals. Interactive kana conversion is not available.

Interactive demonstration

Light signals

Flash a typed International Morse message on screen at 10 WPM. This demonstrates timing, not reception at a distance.

Text spelling tool

NATO spelling alphabet

Turn A–Z and digits into spoken spelling words; compare all 26 letters and the separate number reference.

Cyrillic reference

Russian Morse

Compare 33 Russian letters, shared signs and complete example signals. The main translator does not accept Cyrillic input.

Text encoder and grid

Tap code

Encode letters as row/column tap counts in the C/K 5×5 grid. Decode manually with the chart; digits and punctuation are omitted.

Choose the representation first

Morse carries character groups as marks and gaps. NATO code words help spell letters in speech. Tap code uses row and column counts. Binary here represents UTF-8 bytes. These systems do different jobs; a shared short/long or on/off appearance does not make their output interchangeable.

For text-to-Morse or written Morse-to-text, use the main translator. For a recording or a photo, the guides explain a manual inspection process. A language reference is useful for looking up a known script, but it is not a language translation service.
