This is my personal library for working with Morse code. Presently it contains
|
|||
|
|
the TextToMorse class which takes a string and returns a byte array in WAVE
|
|||
|
|
file format containing the contents of the string translated into Morse code.
|
|||
|
|
This is somewhat like what ebook2cw does, but not nearly as flexible (only
|
|||
|
|
WAVE output rather than mp3 or ogg, a much more limited number of characters
|
|||
|
|
supported). On the other hand, CWLibrary is written in C# using only the .NET
|
|||
|
|
framework libraries, so if you're working on a .NET project it may be a better
|
|||
|
|
fit for your needs...
|
|||
|
|
|
|||
|
|
Here is an example program that uses this library to write out a file named
|
|||
|
|
"hello.wav" that plays "hello, world" in Morse code:
|
|||
|
|
|
|||
|
|
+-----------------------------------------------------------------------------+
|
|||
|
|
using CWLibrary;
|
|||
|
|
using System.IO;
|
|||
|
|
|
|||
|
|
class Program
|
|||
|
|
{
|
|||
|
|
static void Main(string[] args)
|
|||
|
|
{
|
|||
|
|
TextToMorse converter = new TextToMorse();
|
|||
|
|
string text = "Hello, World";
|
|||
|
|
|
|||
|
|
byte[] outfile = converter.ConvertToMorse(text);
|
|||
|
|
|
|||
|
|
FileStream stream = new FileStream("hello.wav", FileMode.Create,
|
|||
|
|
FileAccess.Write);
|
|||
|
|
stream.Write(outfile, 0, outfile.Length);
|
|||
|
|
stream.Close();
|
|||
|
|
}
|
|||
|
|
}
|
|||
|
|
+-----------------------------------------------------------------------------+
|
|||
|
|
|
|||

The above program will generate 20 WPM Morse code with a pitch of 600Hz. If
|
|||
|
|
you want 15 WPM, just pass it to the constructor:
|
|||
|
|
|
|||
|
|
TextToMorse converter = new TextToMorse(15);
|
|||
|
|
|
|||
|
|
If you want 5/18 WPM (character speed as if sending at 18 WPM, but spacing
|
|||
|
|
between characters and words added for an overall speed of 5 WPM) you would
|
|||
|
|
call the constructor thus:
|
|||
|
|
|
|||
|
|
TextToMorse converter = new TextToMorse(18, 5);
|
|||
|
|
|
|||
|
|
If you also wanted to raise the pitch to 800 Hz, the following would do so:
|
|||
|
|
|
|||
|
|
TextToMorse converter = new TextToMorse(18, 5, 800.0);
|
|||
|
|
|
|||

|
|||
|
|
you want with it.
