Detailed Description

This class provides a voice recorder in a HAW_deck object.

Voice recording is feature for voice browsers only (VoiceXML). The recorded voice input will be sent encrypted as multipart/form-data to some other url, which normally will be another PHP/HAWHAW script. Here you can store the received data as .wav file on your server, play it to the user, or do whatever you want. Saving of the received voice data is similar to normal PHP file upload handling.

Voice recording is a very powerful feature which offers many oportunities to create high-sophisticated voice applications.

Examples:

$myRecorder = new HAW_voicerecorder("http://www.foo.com/script.php", "Please speak after the tone");

$myRecorder = new HAW_voicerecorder("http://www.foo.com/script.php", "You have 2 minutes from now");
$myRecorder->make_beep(false);
$myRecorder->set_maxtime(120);

... and in http://www.foo.com/script.php we store the received wav file like this:
move_uploaded_file($_FILES['haw_recording']['tmp_name'], "/voice/message.wav");
