This is a Stage icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,800 icons, all in the same style and quality.
This shape has a rectangle on the bottom which is split into two horizontally. The bottom is slimmer than the top. On top of it are 4 curved lines starting from the right and ending on the left of the rectangle like a rainbow.
