Describe the problem or limitation you are having in your project

This is the "formal" proposal version of a discussion that I created a few days ago.

Those 3 icons only differ by a tiny color dot and I find them not symbolic enough to be pleasant to read.
As a bonus, the music notation used in the icon is, well, a music notation, not something related to sound in general.

Currently, the icon is made up of 2 parts:

1. the multi-colored note, this gradient having the "sound" meaning,
2. a small colored play icon, colored according to the spatialness of the node.

My point of view is the following:

• the gradient is useless. A good icon would convey the audio part much more naturally than the current design.
• the spatial part is way too small to be useful.

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

• Use an actual speaker icon instead
• Color it fully according to spatiality: either white for AudioStreamPlayer, blue for AudioStreamPlayer2D or red for AudioStreamPlayer3D
• Keep the gradient in AudioStreams since there is no common icon for them (some use the note, some don't)

Basically use the same icon as most other software:

blender	ubuntu	unity	godot, in the 3D view

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

a good icon would have to be designed by someone competent.

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

It's used in 99% of godot projects.

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

it's core already
