HTML5 Audio
To add HTML5 audio to your website you can use the 'HTML5 audio' object which is available in the 'Media' section of the toolbox.
Unfortunately there is no single audio format that works with all browsers. Different browsers do support different formats, so you will have to create multiple formats depending on which browsers you want to support. You can configure multiple alternative formats in the properties of the HTML5 audio object.
For more details about supported formats please go to:

Audio files can be pretty large, so it's recommended to upload the audio files to your website manually. This can be done with either the built-in FTP manager or a separate file transfer tool.
Instead of using a local link you them have to specify an absolute link to the audio file. For example: http://www.yourwebsite.com/audio.mp3
Quick 'n Easy Web Builder also supports other formats like Windows Media and RealAudio, but these formats are becoming less popular.
