Red Rock Sound **Measure** is a sophisticated metering and measurement tool that allows you to visually analyze your audio signal in several useful ways. Too loud mixes often sound squashed, and in long mixing sessions your ears often get used to the squashed sound so you´re losing objectivity. Measure will show you Peak and RMS values of your mixes, phase correlation between Left and Right and the number of Overs. When working with a stereo signal, choose Sum/Diff mode to make sure there is no energy drop in the sum which could be caused by phasing problems and that the difference (diff) is not too low compared to the sum. To save space in your Reason rack, we duplicated the key indicators at the front folded panel.

Features

• Selectable RMS Reference Waveform;

• Adjustment RMS Averaging Time;

• 40 dB Scale in 1 dB steps.

There is a potential for ambiguity when assigning a level on the dBFS scale to a waveform rather than to a specific amplitude, since some choose the reference level so that RMS and peak measurements of a sine wave produce the same number, while others want the RMS and peak values of a square wave to be equal, as they are in typical analog measurements. Measure allows you to select RMS Reference Waveform Sine or Square:

• For the case in which the RMS value of a full-scale SQUARE wave is designated 0 dBFS, all possible dBFS measurements are negative numbers. A sine wave could not exist at a larger RMS value than −3 dBFS without clipping, by this convention. This is the convention used in Euphonix meters;

• For the case in which the RMS value of a full-scale SINE wave is designated 0 dBFS, a full-scale square wave would be at +3 dBFS. This is the definition specified in AES Standard AES17-1998 and IEC 61606 and used in Dorrough meters and meters with K-System guidelines.

Reference Level (for Sine RMS reference waveform only!):

• 20 dB AES / K(atz)-20 / SMPTE;

• 18 dB EBU;

• 14 dB K(atz)-14;

• 12 dB K(atz)-12.

Measure meter are able to detect and display the number of Overs, which are defined as 3 samples or more that exceed 0 dBFS (-0.0008 dBFS). What is OVERS?
