Are there WPS tags for equalizer & crossfade settings?

<< < (2/3) > >>

KiwiCam:
Thanks Chronon.

After doing a lot of reading about Graphic Equalisers, I realise now  :P , that that not actual what I'm wanting to recreate. It's a Spectrum Analyser  :D. I just want to display graphically in the WPS which "displays the volume for the various frequencies in the signal."

Is this possible? What theme tags should I be looking at please? Or, would I just be limited to the Peak Meter left and right channels?

I see that there is a plugin for a Spectrum Analyser. I found this on youtube and it's on my Clip:

But I can't find it here:

JdGordon:
no, there is currently no tag which can make a bar from any other tag

edit: actualy, thinking about it this shld be pretty easy to implement

Chronon:
To get a proper spectrum analyzer in the WPS, it seems you would need viewports to be able to view the output of plugins.

Unfortunately, the PluginIndex has fallen out of date a bit.  Simply adding stubs that list the supported players for each missing plugin page would help bring the table up to date (though there may be plugins that aren't listed in the manual too).

Bear in mind that I know nothing about the intricacies of sound:

I see that in the Theme Tags there are 5 bands. I gather that each bands range of frequencies is set by the "eq band X cutoff" value, for each of the five bands. I assume. So, if I could get the volume level (is that the amplitude?) for each set band, as a percentage, then I could use those to make a 5 band Spectrum Analyser, with each band being in a progress bar.

Does that sound right? I just want something for show, but that actually is based on real-time stats.

JdGordon:
Do you want the static setting values? or do you want an actual eq visualisation going?
