Reimplement colored gradient on AudioStreamPlayer icons

[vPumpking]

Describe the project you are working on

any game

Describe the problem or limitation you are having in your project

As a person with real bad eyes, the gradient on the previous version of the audiostreamplayer icon really helps me a lot in recognizing it.
I'm sure other people face the same problem. i suggest we do that for accessibility

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Implemement back the gradient on the new icon.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

If this enhancement will not be used often, can it be worked around with a few lines of script?

no

Is there a reason why this should be core and not an add-on in the asset library?

it's an icon

This was changed to implement:

• Use a colored speaker icon for AudioStreamPlayers #9688

Which improved usability from the old icons, to indicate type, implemented in:

• Change the AudioStreamPlayer icons to be clearer. godot#92116

How would you suggest making all the audio steam players visible, without making it confusing to tell the 2D, 3D, and non-positional ones apart

[vPumpking]

yeah you're right, would be difficult

I recall there being a discussion about adding some sort of shape cue to differentiate 2D and 3D nodes aside from their color. With an (admittedly very quick) search of the godot-proposals repository I didn't spot it, but I feel like it could be worth merging this discussion into that one, if it's still being considered.

You're thinking about #794 🙂

I guess it could be an additional gradient overlaid on top. It would begin from pure white/blue/red on the left and transition to transparent.

I'm not even sure if it's possible to do this with SVGs (probably yes).
Alternatively the speaker could be coloured and the sound waves could keep the audio gradient, which achieves a similar effect but looks less... cool.

Unsure if reverting the icon a bit is very desired at the moment, though.
