Description

C'est un lecteur audio simple multi-pistes: il permet de lui fournir plusieurs fichiers et il les lit l'un après l'autre
Il fait à peu près la même-chose que le http://www.alsacreations.fr/dewplayer, mais avec le code source en plus.
L'exemple d'utilisation: http://www.uaemon.com/public/flash/uaemon_skin.html

Source / Exemple : 


// Variables
var guide:Sound = new Sound();

Conclusion :


C'est un lecteur simple pour un besoin particulier.
Un lecteur en flash permet aussi de contourner le problème de compatibilité entre les différents OS.
