How to change audio file

[hugsbrugs]

Hi there, I'd like to know how to change default audio files :
This does not work

require_once __DIR__ . '/vendor/dapphp/securimage/securimage.php';
echo Securimage::getCaptchaHtml([
	'audio_path' => __DIR__ . '/php/secureimage/audio/en/'
]);

When I read docs :

$img = new Securimage();
$img->audio_path = $img->securimage_path . '/audio/de/'; // switch to German

but how do I then call a static method with an instanciated class ?

Thanks for your lights !

make it easier and there will be no problems:

//put in securimage_play.php; $img->audio_path = dirname(__FILE__).'/audio/fr/';

in html:

<a target="_blank" href="/securimage_play.php"><img class="captcha_play_image" width="32" src="/c/audio_icon.png" alt="Play CAPTCHA Audio"></a>

And don't use classes, it complicates the code.
