This is sound of SOS International Morse Code Distress Signal.
You can use it in videos, trailers, movies, games, cartoons,
animations, quizzes, presentations, music and lot more…
Morse code is usually heard at the receiver as a medium-pitched on/off audio tone (600–1000 Hz)
That’s why for the signal frequency I have choosen 800 Hz, which is exactly in the
middle between mostly used frequencies 600-1000 Hz.
The unit length is equal to 50 ms which is 1/20 of a second. This unit length can give typing speed around 25 wpm (words per minute).
Morse code is composed of five elements:
- Dot – one unit long
- Dash – three units long
- Gaps between dots and dashes within character – one unit duration
- Gaps between letters – three units long
- Gaps between words – seven units long
Audio signal is peaking at -3 dBFS
After SOS signal there is seven units gap, so the file is suitable for looping.
