SOS in Morse code - hear it and flash it
SOS is three dits, three dahs, three dits — usually sent as one continuous distress prosign, not three polite letters with long gaps. Tap Play for audio, or open the flashlight tool for a screen blink. Pattern practice only; use real emergency channels when it matters.
When to use
Learning the rhythm; checking a puzzle that asks for SOS; practicing a visible/audible pattern in a safe drill; confirming timing at a chosen WPM.
Better elsewhere
Real distress → local emergency services and proper signaling training. This page only teaches the pattern.
Assumptions
Pattern `...---...` with prosign-style tight spacing by default; optional letter-spaced S O S when teaching the gap difference. Audio/light need a user gesture.
Examples
Input
Play SOS once at 12 WPM
Result
Count 3-short / 3-long / 3-short
Slow enough to feel the rhythm before you speed up.
Input
Open flashlight · SOS preset · dark room
Result
Full-screen blink practice (safe drill only)
Input
Compare letter-spaced S O S vs continuous prosign
Result
Gaps change the habit — distress uses the run-on form
How it works
- Fixed SOS element sequence is ready on the console.
- Play schedules tones via the shared timing engine at your WPM/pitch.
- For light practice, open flashlight with the SOS preset — same on/off idea, visual channel.
S = ... · O = --- · continuous prosign ≈ ...---... · dit ms ≈ 1200 / WPM
Gotchas
- “Save Our Souls” is a backronym — the signal was chosen for the pattern, not the English phrase.
- Sending S, gap, O, gap, S is not the same as the continuous prosign used as distress.
- Phone flashlight APIs vary; screen flash is the reliable web fallback.
- Pattern practice only — use real emergency channels when it matters.

The rhythm that matters
SOS is three short, three long, three short — usually sent as one continuous distress prosign, not three polite letters with long gaps. This page prefills the translator so you can hear and adjust WPM immediately. For screen blink practice, open flashlight with an SOS preset.
Safety boundary
This teaches a pattern. In a real emergency use local emergency services and proper signaling training.
“Save Our Souls / Ship” are memory aids — handy mnemonics, not the operating reason you need on the air.
