AUDIO Scopes

About Audio Scopes

Traditional audio scopes are linked to the audio routing and react to the mapping of the channels.

Therefore you can monitor independently channels belonging to different audio soundfields, or monitor a particular soundfield instead.

  1. Values display in red on an audio scope mean that the measure is beyond the target that has been chosen for the analyses (i.e EBU R128). 
Alert
All audio scopes are LIVE scopes.
Loudness Global measures are available after an Analysis and appear on the timeline's GRAPH.


Audio Levels

Audio levels are measured in decibels (dB), which quantify the intensity of sound. Decibels are a logarithmic unit, meaning that a small increase in dB can represent a large change in sound intensity or loudness.



Audio Levels Layout

The appearance of the Audio Levels scope vary according to the LAYOUT chosen for the scope.

The LAYOUT parameter is available in the CONTROL PANEL > TOOLS> ROUTING> AUDIO:



AUTO Layout

When the Layout is set on Auto, then the Audio Levels will display the different soundfields according to the timeline, to a maximum of 16 channels. The unused channels will be displayed as stereo pairs.
  1. The routing audio is then automatically set to SOLO play the first audio soundfield.
  2. Toggling the soundfields on the Audio Routing will be reflected in the corresponding soundfield of the VU-Meters.

Example with a timeline with two soundfields, 5.1 and 2.0:

Audio Levels in AUTO Layout

Alert
If the timeline has more than 16 audio channels, selecting them in the Audio routing will switch the VU-Meter in custom mode, and it will only display the routed channels.

NONE Layout

When the Layout is set on None, then the Audio Levels will display 16 mono channels, that will be playing the audio according to the routing. This mode allows to play for example two different soundfields at the same time for synchronization purpose, or to test each channel individually.

Audio Levels with Layout NONE



Features

  1. Automatic file audio layout detection mode
  2. VU meters (EBU or SMPTE recommended practice)
  3. True Peak meters (red line)
  4. Sample Peak meters
  5. RMS meters (over 1 frame)
  6. Choice of display scales: 60, 96 or 144 dB


VU meters (Volume Unit meters)

These meters are designed to indicate the perceived loudness of the audio signal. They respond more slowly to sudden peaks and are often used to monitor the overall loudness of a mix.

Sample Peak meters

Peak meters show the highest instantaneous level of the audio signal. They are crucial for preventing clipping and ensuring that the signal doesn't exceed the maximum allowed level. 

True Peak meters

Take into account inter-sample peaks, which can occur between sample points in digital audio and cause clipping even if the regular peak meter doesn't show it.

RMS meters (Root Mean Square):

RMS meters display the average signal level over a specific period of time. They provide a better indication of the perceived loudness of the audio signal than peak meters. 



Audio Entropy

The Audio Entropy diagram provides a unique representation of the audio in terms of spectral content and localization in the surround space. Whatever the speaker layout is, from 2.0 to 9.1.6, the Entropy diagram materializes how the audio is rendered for each speaker, providing an unrivaled 3D information, especially when using NGA content: the objects movements in a NGA file are not necessarily reflecting the actual "movement" of the sound in the volume.
