This is a Audio Wave Filled 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 12,400 icons, all in the same style and quality.
It is a sequence of perfectly vertical lines. The lines are uniform in weight/width, but vary in height. They are all vertically aligned along an invisible horizontal center line. The lines vary from shortest to medium to longest, then back down to shortest. This pattern repeats one more time.
