Measurement Functions<br />
Broadcast levels are limited to a maximum output peak level. This<br />
is in order to not to overload the transmission lines and to avoid<br />
unpleasant and audible distortions. During tuning through the radio<br />
stations it is clearly noticeable, that some channels are much louder<br />
than others; purposely to increase awareness!<br />
This is accomplished by using compressors and other dynamic<br />
signal processing devices. The intention is to make the material as<br />
loud as possible without exceeding the maximum peak level. Simply<br />
feed the digital audio signal into the <strong>Digilyzer</strong> and it displays for both<br />
channels the peak- and VU-levels. The closer the VU level is to the<br />
PPM level, the higher is the compression of the audio material.<br />
