Morse Code Generator

Tool Introduction

The Morse Code Generator is a convenient online tool designed to help users convert any text message into Morse code audio signals. By simulating the traditional telegraph's "dit" and "dah" sounds, you can intuitively understand the auditory form of Morse code. This tool provides a wealth of customizable options, including "Sample Rate", "Dot Duration", "Dash Duration", "Pause between symbols", "Pause between words", "Frequency", and "Volume", allowing you to adjust the characteristics of the generated audio according to your personal needs or teaching experiments.

How to Use

1. In the "Text to encode" input box, enter the text content you wish to convert to Morse code, for example, "Hello World".
2. According to your needs, adjust the audio generation parameters below, such as "Sample Rate", "Dot Duration", "Dash Duration", "Pause between symbols", "Pause between words", "Frequency", and "Volume".
3. After confirming that all parameter settings are correct, click the "Generate" button.
4. The tool will display the corresponding Morse code text in the result area and provide a playable Morse code audio file.

Input Parameter Description:

• Text to encode: Required, the plain text you want to convert to Morse code, supports any characters. Default value is "I love you.".
• Sample Rate: Required, the audio sampling frequency, in Hz, ranging from 8000Hz to 192000Hz. Default is 44100Hz.
• Dot Duration: Required, the duration of the "dot" signal in Morse code, in seconds (s), ranging from 0.01s to 5s. Default is 0.1s.
• Dash Duration: Required, the duration of the "dash" signal in Morse code, in seconds (s), ranging from 0.01s to 5s. Default is 0.3s.
• Pause between symbols: Required, the pause time between Morse code dot and dash symbols, in seconds (s), ranging from 0s to 5s. Default is 0.1s.
• Pause between words: Required, the pause time between words, in seconds (s), ranging from 0s to 10s. Default is 0.7s.
• Frequency: Required, the base frequency of the generated audio, in Hz, ranging from 100Hz to 5000Hz. Default is 600Hz.
• Volume: Required, the playback volume of the generated audio, no unit, ranging from 0 (mute) to 1 (maximum volume). Default is 0.3.

Output Result Description:

• Results will be presented in a list, including two columns: "Morse Text" and "Morse Audio".
• "Morse Text" displays the Morse code symbol sequence after converting the input text.
• "Morse Audio" provides a playable audio player, making it convenient for you to listen to the generated Morse code sound.

Usage Example

Suppose you want to convert "Hello World" to Morse code audio using default parameters.

Example Input Data:

• Text to encode: Hello World
• Sample Rate: 44100 Hz
• Dot Duration: 0.1 s
• Dash Duration: 0.3 s
• Pause between symbols: 0.1 s
• Pause between words: 0.7 s
• Frequency: 600 Hz
• Volume: 0.3

Operation Demonstration:

1. Enter "Hello World" in the "Text to encode" box.
2. Keep other parameters at their default values.
3. Click the "Generate" button.

Expected Output Result:

Principles of Morse Code

Morse code is a signal code that is on and off, representing letters, numbers, and punctuation marks through short signals of different durations (dots, usually represented as "dit") and long signals (dashes, usually represented as "dah"), as well as silent periods of different lengths. It was invented by American Samuel Morse in 1837, initially to be used with telegraph machines for long-distance communication. The brilliance of Morse code lies in its use of simple binary signal combinations (signal/no signal) to transmit complex information, greatly promoting the development of early long-distance communication.

Basic composition:

• Dot (Dit, ·): A short signal tone.
• Dash (Dah, -): A signal tone lasting three times the duration of a dot.
• Pause within symbols: The pause between dots and dashes, usually the same duration as a dot.
• Pause between characters: The pause between characters, usually three times the duration of a dot.
• Pause between words: The pause between words, usually seven times the duration of a dot.

This tool is based on these principles, converting your text into auditory Morse code by generating audio signals and silent segments of different durations.

Frequently Asked Questions

• Q: What input text formats does the Morse Code Generator support? A: This tool supports any UTF-8 encoded plain text input, including English, numbers, and common punctuation marks. For non-standard Morse code characters, the tool may ignore them or use specific replacement rules.
• Q: What format is the output audio file? Can it be downloaded? A: The output is an audio stream played directly on the browser page, usually a common audio format supported by browsers (such as WAV, MP3, or Ogg). Most modern browsers allow users to download by right-clicking the player or using built-in browser functions.
• Q: Are there any standards for the duration of dots and dashes in Morse code? A: In international Morse code standards (such as ITU-R M.1677-1), the duration of a dash is three times that of a dot, the pause within a character (between dots and dashes) is the same duration as a dot, the pause between characters (letters, numbers) is three times the duration of a dot, and the pause between words is seven times the duration of a dot. This tool allows you to customize these parameters for experimentation or to meet special encoding needs, without strictly adhering to international standards.

Notes

• Input Data Format: Please ensure that the "Text to encode" is plain text. Although multi-line input is supported, newlines usually do not have a direct corresponding encoding in Morse code and may be treated as spaces or ignored.
• Parameter Validity: Please pay attention to the valid range of all numerical parameters (e.g., volume 0-1, frequency 100-5000Hz, etc.). Values outside the range may lead to audio generation failure, abnormal sound quality, or program errors.
• Audio Generation Time: For very long input text, audio generation may take a longer time, please be patient.
• Browser Compatibility: It is recommended to use the latest versions of modern browsers such as Chrome, Firefox, Edge to get the best audio playback compatibility and user experience.
