Quick answer

Use the visual calculator

Analyze measured key-down and key-up durations, estimate the dot unit and WPM, classify each pulse and gap, quantify timing jitter and reconstruct the likely message.

Worked example: Durations clustered around 60 and 180 ms indicate approximately 20 WPM dots and dashes.

How this visual Morse calculator works

The page separates input, transformation and verification so the result remains understandable.

1. Enter

Alternating durations is supplied using the calculator-specific controls.

2. Normalize

The browser validates symbols, timing values, separators, files or device permissions required by this method.

3. Calculate

The analyzer estimates the base unit from the lower pulse cluster, compares each duration with 1, 3 or 7 units and reports relative deviation. WPM is estimated as 1200 divided by the fitted dot duration.

4. Visualize

The timing scatter display reveals the signal structure instead of presenting only a text answer.

5. Verify

Compare the mapping, timing units, decoded characters, measured pulses or design dimensions shown in the result.

Method, timing and worked example

The calculation follows the rule appropriate to this individual tool.

Method used

Worked example

Durations clustered around 60 and 180 ms indicate approximately 20 WPM dots and dashes.

Change the inputs to reproduce or extend the example

Standard timing reference: At ordinary International Morse timing, a dot lasts one unit, a dash three units, the gap inside a character one unit, the gap between characters three units and the gap between words seven units. The WPM tools use the PARIS timing convention, while Farnsworth mode lengthens spacing without slowing individual dots and dashes.

What this calculator does well

Robust median unit estimate

Jitter and outlier report

Signal reconstruction

Important limitations

Very irregular hand-sent code can require manual correction.

For camera, microphone, audio and image analysis, signal quality and browser support affect the result. Treat uncertain output as a candidate interpretation and verify it against the source.

Morse Code Timing Analyzer questions

Answers to common questions about the calculation and visual result.

What does the Morse Code Timing Analyzer calculate?

Analyze measured key-down and key-up durations, estimate the dot unit and WPM, classify each pulse and gap, quantify timing jitter and reconstruct the likely message.

Which Morse standard does this tool use?

The calculator uses International Morse code for supported letters, digits, punctuation and common procedural signals. Timing follows the standard one-unit dot, three-unit dash, one-unit element gap, three-unit letter gap and seven-unit word gap unless a dedicated timing control changes spacing.

How should I read the visual result?

Dots appear as short circular or short-duration marks, while dashes appear as longer bars or pulses. The live visual is synchronized with the text result so each transformation can be inspected instead of accepted as an unexplained answer.

Does this calculator upload my message or recording?

Calculations run in the browser. Camera, microphone, audio and image tools process the selected stream or file locally in the page; the plugin does not send those inputs to a calculation server.

What can affect accuracy?

Very irregular hand-sent code can require manual correction.

Can I use the result for practice or design?

Yes. Copy and print controls are included, and tools that create reusable audio, vector, image or stencil output provide a download control. Verify any safety-critical or permanent design before relying on it.
