Under-reads very short peaks slightly like a traditional BBC PPM. Fallback ballistics are accurately modelled but the attack time (eg the BBC spec of 2.5dB down for a 10ms burst of 5Khz) is only approximate. Very short peaks such as 1.5ms register -4dB instead of -9dB as per spec. The fallback time from 1 to 7 is in line with BBC specifications, 2.5 to 3 seconds. You may prefer a faster fallback, especially as there are the peak markers, so the fallback time can be adjusted by means of an arbitrary value entered on the options page. A value of 2 corresponds to the BBC PPM spec. Values up to 10 speed up the decay.

Mono matrix can be set to M = (A+B) – 3dB or 6dB. Traditionally the BBC have used M3, though M6 is increasingly used. Channels can be labelled L & R or A & B. Displays Left, Right, Mono (sum) and Stereo (difference) simultaneously.

The peak markers can be set to hold the peak. Click on the window to reset.

There is also a 20dB button. This increases the gain of of the Stereo difference indication  by 20dB (10 times). M, L & R are not affected.

The colour of each bar can be set to any colour from the options screen. By default all bars are green but it possible to have, for example, red and green for A and B.

For Windows XP, Vista, 7 or 8.
