Audio Measurement

As the broadcast world continues to adopt loudness based normalisation at an ever increasing rate, it has become vital to be certain that any content distributed falls within the accepted range for both short and long term values and does not exceed any maximum true peak limits.

Accurate measurement tools that can act as a “watchdog” and can trigger alarms if any preset values are exceeded are an invaluable aid to ensuring compliance and comfort.
