( peak program meter) An audio meter originally developed in Europe to accurately measure and display peak audio signals (as opposed to average audio signals; see VU meter). The PPM augments the VU meter and it is normal to find both in modern recording studios. The PPM is particularly valuable for digital audio recording or signal processing due to the critical monitoring required to prevent exceeding 0 dBFS. There are several Europena PPM specifications, but no one universal standard; although the German DIN specification 45406 functions somewhat as a de facto standard. An interesting aspect of PPM design is that rather than respond instantaneously to peaks, they require a finite integration time so that only peaks wide enough to be audible are displayed. DIN 45406 translates this into a response that is 1 dB down from steady-state for a 10 ms tone burst, and 4 dB down for a 3 ms tone burst (this is consistent with the other commonly seen specification of 2 dB down for a 5 ms burst -- both requirements are satisfied by an attack time constant of 1.7 ms (BBC requirement is 2.5 ms). The specified decay rate of 1.5 seconds to a -20 dB level can be met with a 650 ms time constant.
