The Peak Programme Meter (PPM) was originally developed by the BBC to overcome the shortcomings of the VU meter, which is notoriously bad at showing the peak signal level. The VU meter is average reading, and the ballistics are important if an accurate reading is to be obtained.

In general, then, the SVI or VU meter tends to show the average signal voltage, and gives a reasonable indication of perceived loudness. The Peak Programme Meter or PPM is a much more elaborate design and pre-dates the VU, as its development started in 1932, with the meter we know today appearing in 1938.

Meters which monitor audio levels are typically one of two varieties: VU (Volume Unit) or PPM (Peak Program Meters). Though both perform the same function, they accomplish the function in very different manners. A VU meter displays the average volume level of an audio signal. A PPM displays the peak volume level of an audio signal.
