Audio MeteringA 60-minute tutorial on audio and metering technology written by Eddy B. Brixen. Audio is much more than the noise that accompanies the picture. In today
VU (Volume Unit) meters used to be the mainstay of audio metering systems, but they have been replaced by LED metering in a great many mixers and other applications. Even in software, the most common level meter is made to look like an LED meter, although there are quite a few analogue software meters available as freeware. 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.
About PPMulator+ Audio Metering A professional metering plugin that integrates perfectly into all audio programs capable of plugin hosting. It supports different metering standards, a peak log feature, stereo as well as surround processing. The interface can be resized and configured to fit the users requirements optimally.
The metering capabilities of the DPMP plug-in let you control and monitor your audio signal exactly the way you want: almost every aspect of the meters can be customized. It now proposes five different scales, including Bob Katz's very popular K-System scales (K-12, K-14, K-16 and also the extra K-10). The graphs show the evolution of the audio envelopes over time, and the mid-side switch lets you verify mono compatibility problems and check the stereoness of your audio sources very easily.
