Q. where / what function / who is drawing the Analyser node frequency or<br>
time domain visualization. I don't see anything in Page Source looking at<br>
Analyser node fields for output.<br>
<br>
Thanks, Doug<br>
more..<br>

<br>
- web audio example of visualization using Analyser node gets a buffer of<br>
spatial or time-domain data on each draw loop, and draws it.<br>
Currently web3d Analyser node has no output fields defined for the spatial<br>
or time-domain output data.<br>
<br>

It is a mystery to me how we would use it to visualize without access to<br>
the data.<br>
