Discussion: Pros & Cons of a potential WPS Tag Feature Request
seani:
Mea culpable on the functionality of %pv, I didn't look at the WPS docs, I think I found a link to an old IRC / forum discussion that indicated only 10 maximum steps were available up to 0db
So if I have it right, %pv automatically scales the volume range from -whatever db to 0db so that if, for instance, 5 images are specified, and the range is -70db to 0db on a player, the image changes on 14db boundaries; if the range is -60db to 0db and there are 12 images, the images change on 5db boundaries?
And the range >0db is represented by a single image, not scaled, and not otherwise available in any way to a WPS author?
Edited: spelling errors
JdGordon:
yes... I'm thinking a nice compromise is adding a conditional for how far over 0 the volume is which would please almost everyone..
Llorean:
The range above 0db is also available as actual numbers. It just can't be split into multiple images and you can't replace the numbers with imaginary numbers of your own choosing.

This is where we part company in our viewpoint I think.
As soon as you're displaying the volume as anything other than the db figure, whether it's a graphic or an arbitrary scale of your own devising, it's all imaginary, and all equally "useless" (if unaccountably popular).
If I understand correctly, past the 0db level I can press my volume button a further 6 times on the Gigabeat and there'll be no change in the volume display (confirmed with a play). Or, alternatively depending where I am, I can decrease the volume by 6 additional steps and I'll get no feedback , although in both cases the actual volume will change from various levels of ear-splitting.
My only feedback on the way down is to note that if I keep pressing the volume down button, eventually I may get a different image.
Llorean:
This is true for *most* levels of volume. The volume image is only a relatively scant number of pixels wide, yet the range is quite significant. So yes, you could also say that for changing the volume level at almost any level of volume that "I have to press it X times before the display changes."
So what's the problem again?
At no point does the image give you any detailed feedback, and unless you use one of a relatively significant size it certainly doesn't give you more feedback than either your ears your your fingers. Even if the image were as large in pixels as the number of steps, you wouldn't be able to count the pixels to get an exact amount unless you had very, very good eyes. The main usefulness of it is that you can look at the image and get an approximate feeling of "loud" or "soft." The clipping image gives you the added bonus of "loud and almost certainly distorting."
