Jung-child.jpg[edit]

Hi. I have just uploaded a rescan of my original Image:Jung-child.jpg. The new one was done with a much better scanner and at a higher resolution. I just want to let you know that I didn't replace your version out of spite or anything. I just happened to get a new scanner. :) I didn't edit the image much as far as contrast, etc., goes, but if you feel such changes are necessary feel free to make them.

Hello, Iainf!

Tip: Add categories to your images

Thanks a lot for contributing to the Wikimedia Commons! Here's a tip to make your uploads more useful: Why not add some categories to describe them? This will help more people to find and use them.

Here's how:

1) If you're using the UploadWizard, you can add categories to each file when you describe it. Just click "more options" for the file and add the categories which make sense:

Uploadwizard-categories.png

2) You can also pick the file from your list of uploads, edit the file description page, and manually add the category code at the end of the page.

[[Category:Category name]]

For example, if you are uploading a diagram showing the orbits of comets, you add the following code:

[[Category:Astronomical diagrams]]
[[Category:Comets]]

This will make the diagram show up in the categories "Astronomical diagrams" and "Comets".

When picking categories, try to choose a specific category ("Astronomical diagrams") over a generic one ("Illustrations"). Pro-tip: The CommonSense tool can help you find the best category for your image.

Thanks again for your uploads! More information about categorization can be found in Commons:Categories, and don't hesitate to leave a note on the help desk.

VU meter / SVI[edit]

Hello,

your Fichier:VU-meter-reponse-graph.svg is on the French wikipedia Vu-mètre. I was wondering where you'd get the data? The standard says the needle must reach 0 dB from -infinity in 300 ms. Your needle seems faster than that. Or am I wrong in my expectations?

Also, the scale on the left does not reflect the (also standard) VU labelling.

PolBr (talk) 20:22, 18 May 2012 (UTC)

Hello again!

I have coded a VU-meter response exploration:

They are all coded by a Java program that grabs the value of the signal and produces a RMS value for the time interval corresponding to 1 pixel (160 to a second), filters it so that the impulse response fits the standard (from down to 0VU in 300ms, 1 to 1.5% overshoot), and converts the value to the scale as is on a standard (needle) meter. If I made no mistake in the programs, they represent fairly what a standard needle VU-meter (SVI) does.

Out of curiosity, I would have entered a signal fitting the one that is on your drawing, but I couldn't in any simple way extract values from the cubic splines that represent the signal in your graphics. So I took an actual percussion recording (somewhat compressed, as a matter of fact). Even though it's not the same signal, I think the time response shown on your graphic is not standard; the slide up is much too steep.

My graphics are actually derived from your design, so

  1. Do you want to be credited for the original idea?
  2. What is your opinion on my design? Is it getting too technical or complicated?
  3. Now it can be simply done, do you think response to other types of program contents would interest people who access the VU-meter pages (English version: 54 views in the last 90 days; French:1939 views)?

Regards -- PolBr (talk) 11:00, 21 May 2012 (UTC)

Not simple issues[edit]

I credited the original idea.

The question of the scales is not simple at all to me.

  • If the signal graph follows the SVI scale, all levels above -15 dB FS and below minus forty-some go out of the graph, and the steps do not linearly reflect the signal level
  • If the VU graph is linear, the great design hack (or bricolage if you want) that the SVI was is lost. The idea was to compensate a necessarily slow response (several were tested) with a diminutive scale and a tweaked alignment level 8 dB below nominal level.

In the present state, the background shows something much like the indication of a PPM in its upwards moves (to represent it accurately you'd need at least 200 px per second) over full scale (-72 ~ 0 dB FS) linear in dB, which represents the signal for reference. To represent the actual meter response, You have to use full scale if you are going to shows the dips in the program. Now the SVI's 0 VU is at -18 dB FS in Europe (-20 dB FS in North America), and its scale is about exponential from -10 to +3 VU (its designers claimed that this was a good enough approximation of RMS around 0 VU). The SVI scale covers at best half of the PPM scale. The question of the scale and the question of the response are mixed by design. I didn't find any ways of making it any simpler, apart from publishing the slope graph (which hopefully demonstrates the scale) and the step graph (which hopefully demonstrates the response time of the needle). The former was originally my test of the level conversion function of my program, and the latter my test of the ballistics filter function of the same.

I thought the graph was already complicated, and I thought about taking information out of it, rather than stacking more. Yet, with colour, adding a notion of the PPM is straightforward. As I wrote above, the rise time of the signal representation is a good approximation of that of a PPM for this timeline scale. The fallback rate is 1.5 s per 20 dB, that is a 4 horizontal to 1 vertical slope on the graph. I could easily add another pale blue area, topped by a little brighter line to represent that. It would have to be in the background so as to avoid obscuring the signal area.

As for the Loudness measurements, that is not possible in this graph. Loudness as by EBU 128 is computed on four different timespans : true-peak, 400ms, 4s, program length. TC electronics have spent much on the production of relevant graphs. The point is : SVI and PPM supposed good will on the user's part to maintain program quality. The loudness competition showed that goodwill was contrary to the competition spirit (and possibly to market, there is discussion on whether listeners actually prefer loud programs on an expanded timespan). The way out is an industry (ITU, EBU, SMPTE) agreement on what is loudness, of the same kind that made SVI standard in the 1930's.

I'll think about your advice on colour. From my experience with low-cost inkjet printer, I think a large colored area is more troublesome than coloured lines. In a standard HTML page, I would have a CSS @-ruleset for printing and possibly a javascript user prompt to get a black and white rendering. The print version would have no fill or a texture fill for the signal, and for black on white rendering, only the -9, -18, -30 and -60 dB FS lines. In wikimedia, I do not think that this is possible.
