Icecast - Aug 2004 - Re: Viewing Broadcast using scope in a Webpage

Hi Thomas,

So those possible solutions could allow for an audio spectrum analyzer 
to be on a webpage?
(i.e. like the ones you can see on XMMS or WinAmp?)

no, you missunderstood my explanation.
There is no way to do this from xslt.

For such an feature you would either need to stream the content to the client,
decode it there and display the wave-form or decode it on the server and send an
outputstream corresponding to the waveform which would then be displayed by some
sort of applet (java/flash)

IMHO I don’t see any sense in such a feature.

Thomas

Hi Thomas,

Thanks for the info,
I just wanted to experiment with a different effect for my webpage...
I will check out Java/Flash...
