How to get telegraph tone

If it is set as a mobile phone ringtone: You can find the setting for the incoming call ringtone in the settings of the mobile phone, and then search for the telegraph tone to set it.

If you design the telegraph sound yourself, the effect should be like the sound of a telegraph in a movie or TV show. Then you need to have the ability to produce audio, which can be PR. Then, you can look for the onomatopoeia of the telegraph sound (the sound of birds, the recording of film and television telegraph sounds), and then perform software verification, comparison, synthesis, etc. to create it.

The telegraph tone is the sound of ticking, and this method is often used to transmit information during wartime. Morse code consists of two symbols: dot (.) and dash (-) according to the following principles:

1. One point is a basic signal unit, and the length of each stroke is equivalent to 3 points length of time.

2. Within a letter or number, the interval between each dot and each dash should be 2 points in length.

3. The interval between letters (numbers) and letters (numbers) is 7 points in length. The short dot signal "." is "Di" (Di); the long signal "─" maintained for a certain period of time is "Da" (Da).

For example.- represents the letter A, -... represents the letter B, -.-. represents the letter C; ----- represents the number 0, .---- represents the number 1, .. --- represents the number 2 and so on. In this way, "tick" sounds of different lengths and densities can send any text content.
