The icon looks like a triangle with curved edges laying vertical but the point facing left is missing. It is replaced with a smaller rectangle shape with curved edges. At the base of the vertical triangle which is facing left is a small backwards C shape at the center.
This Low Volume icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office
, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,800 icons, all in the same style and quality.
