not too shabby though - only cost £49PPMulator+ is designed to closely-follow the ballistics of mono, stereo, mid-side (MS) and surround (5.1) PPM meters (conforming to IEC 268-10/DIN 45406) and has a number of built-in additional features, including various display style options and a highly-useful Peak Logging process which logs all peaks/overloads against the timecode in the host application where they occurred.
