The icon is shaped like 3 different horizontal stacks of small lines. The first stack has 8 horizontal lines equally spaced on top of each other. The second stack has 4 lines and the third stack has 6 lines.
This is a Audio Wave2 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 13,700 icons, all in the same style and quality.
