# PHP morse code and wav(e) sound file generation
Supported character sets
- Arabic, Cyrillic, Greek (needs conversion to upper case letters (function included)), Hebrew, Japanese
Korean, Latin, Persian, and Thai.
`composer require jblond/morse`
Example UI:
## Examples
```php
stringToMorse('SOS');
$morse = $morse->dotDash($morseBinary);
echo $morse;
$wave = new Wave();
file_put_contents('sos.wav', $wave->generate('SOS'));
```
Non latin example
```PHP
setLetters('Cyrillic');
$morse->stringToMorse('Запомнить');
```
## Morse API
- `setLetters` Change the origin character set (letters / language)
- available: Arabic, Cyrillic, Greek, Hebrew, Japanese, Korean ([SKATS](https://en.wikipedia.org/wiki/SKATS)), Latin (default), Persian, and Thai.
- `getLetters` Get an array of the current selected character set
- `getCharacter` Convert a single character into morse binary code. An invalid character will return a `#`.
- `stringToMorse` Convert a string into binary morse code.
- `dotDash` Convert binary morse code into dot and dash / dit and dah.
### Greek characters
Since the PHP `strtoupper` function fails for Greek, an extra function to do so has been added.
```PHP
setLetters('Greek');
$morse->stringToMorse((new Greek())->stringToUpper('Τέλος εκπομπής'));
```
## Wav(e) API
- `setCwSpeed` set words per minute (cw speed). Default is 25.
- `setSampleRate` default is 11050. An audio CD would be 44100 aka 44.1 kHz (16 bit).
- `setFrequency` set the tone height. Default is 700 (cw tone).
- `generate` get the audio as binary.
