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 jump to the flashlight tool for a screen blink. This page teaches the pattern; it is not maritime certification or a promise that someone will hear you.
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.
When not
Do not rely on a website for real distress procedure. In a true emergency use local emergency services and proper signaling training. This is a practice toy.
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.
- This is a practice helper, not an emergency beacon and not a substitute for real channels.

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. It is not maritime certification, not a beacon, and not a promise that anyone will hear you. In a real emergency use local emergency services and proper signaling training.
“Save Our Souls / Ship” are memory aids — useful mnemonics, not the operating reason you need on the air.
