Are there WPS tags for equalizer & crossfade settings?

[hhannah]

Hi

I already checked the manual, the customWPS wiki (and just in case the flyspray) for my question with no luck; I have no idea if there are wps tags not yet mentioned in those documents, but I would really appreciate if someone knows of the existence of WPS tags for the following information (or knows that no such tags exist!):

1. equalizer settings / equalizer values
2. crossfade values (in/out delays, durations, mode) [in the mentioned docs there are only tags for crossfade setting - type]

------

Are there any other not documented wps tags, by any chance? I gladly offer myself to include them in the customWPS wiki and/or manual

I'd like to make a theme with an Equalizer/Spectrum Analyser for the Clip.

With JdGordon's AMAZING new theme changes, I'm thinking that something like this might be possible now.

Can someone please advise about the original post and whether there are some Equaliser Tag values?

Thanks.

There's the general %St tag to access every setting. But IIRC there's a legacy tag for crossfade as well.

Dumb response of the night (it is here anyway)...

How do I get the setting for each slider position?
Where do I get the settings?
What are the Names of each setting?
Is there a set range for the equaliser?
Is there a Wiki or something in the manual about the equaliser values?

 

Thanks.

C.19 in the manual says to use the settings as named in Appendix D.  Give that a shot.

Thanks Chronon.

After doing a lot of reading about Graphic Equalisers, I realise now  , that that not actual what I'm wanting to recreate. It's a Spectrum Analyser  . 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:

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Unfortunately, the PluginIndex has fallen out of date a bit.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?

[KiwiCam]

An actual visualisation. So, for the above example, that would make a 5 band analyser (and therefore 5 viewports, for example). Each one moving in real-time. Now with your changes via that Theme Test Build, I think that that'd actually be achievable, although probably not on the older MP3 Players, because they'll just not have the grunt.

I'd like to get something like this working:

http://www.youtube.com/watch?v=7gaGd71_lrY - I think five bands is achievable (I like the average band in that one).

[EDIT] I don't know just how accurately I can get the visuals to look, but I do think that it's a great way to try to do justice to the changes that have been made to the Skin Engine. I've been able to push the Clip pretty hard, with just some general testing, so I'm confident that this'll work well.

[KiwiCam]

I'm just wondering if this is possible now.

nothing in this regard has changed
