Description

Are there plans to implement a visualisation of audio in the WMediaPlayer (something similar of what is available in Audacity)?

If not, how can this feature be implemented?

Can you give us some hints?

Hey,

I didn't think it was possible, but apparently Chrome and Firefox have provided an API to access the signal data:

http://www.smartjava.org/content/exploring-html5-web-audio-visualizing-sound

Our current WMediaPlayer does not actually make the audio element available, since it implements a fallback for flash if html5 audio is not available (or does not work for the given file type).

In this case, I would recommend to start from the WAudio class directly, and work with JavaScript and the APIs as in the link above.

Regards,

koen
