Audio() - xspf playlist

This page requires Javascript

This example page uses the Audio object to play files in a XSPF playlist.

• Use the mouse or arrow keys to select a song.
• Top of the playist equals stop.
• The script limits how fast you can effectively switch to a new song. This is needed because stop()ing a currently playing object can fail during timing issues, which will result a bunch of songs playlist at once that you can't stop.
• Switching to a new song will not stop the downloading of a previous one that you switched to. A song is only playable after it is completely downloaded. Changes you make in the playlist may build up (like a queue) while the files are being downloaded and will execute at a later time after a load event fires.
• First song in playlist should start playing automatically once it is downloaded.

The audio object only supports .wav files. .wav files are too big and it affects how useful this is. This playlist uses 60.7MB of audio data. At the least, this shows a use case for mp3 and or ogg support on the audio object.

There's no OnPlaybackComplete event spec/support for the audio object, so the playlist can't automatically advanced to the next song after one is finished playing. Using track length info in the playlist file ( if any ) could possibly be used to set up a timer to work around this problem, but a real event is needed.

There's currently no onerror event spec/support for the audio object. A load event not firing is not the best way for determining an error. onerror is needed so a function can be called ( with event.target support etc.) when the file cannot be loaded for whatever reason.
