New Final Check Metering option

(multi metering tools)



See User Manual for complete details



Available with the Final Check optional key



General GUI explained (see User Manual for all details):

The Final Check Metering layout is divided between the (upper) stereo-panel and the (lower)

surround-panel. Each panel can be collapsed/expanded using the “-”/“+” button indicator (upper-left

corner of each panel).

To select which Bus/Stem you want to monitor, click on the triangle indicator pointing downwards (top

right corner of each panel). You can then select the bus and, the stem you want to monitor. Note that

the stereo panel allows you to select Downmix of any surround bus/stem as well.



Short explanation of the meters available on the main metering page. All these meters are fully

customizable via the setup page (decribed below)

1. Phase meter. The color of the indicator changes to red when the correlation falls below zero.



In surround panel, the little logo displayed additionally shows you which 2 channels are being

monitored. These can be changed via right-click menu or setup page.

2. In stereo panel : PhaseOscillo/PhaseStereoMeter/VUStereoMeter. Available under the Setup

page in order to toggles between the three of them.

In surround panel : Surround meter. Red lines indicate negative phase between two neighbor

channels. Longer red lines indicate phases closer to -1.

3. PPM (white bargraphs) : change the different dynamics and scaling-presets (DIN, Nordic, BBC

or EBU)

4. True Peak Meter (orange bargraphs) : also known as intersample peak meter. This meter

performs an additional over sampling that allows you to spot peaks located between two

samples, and hence to identify areas that are likely to peak after DA conversion.

5. VU-meter (green bargraphs) : a classical VU-meter, with customizable dynamics.

6. PPM, True Peak and VU meter all include a peak hold and overload indicator that you can

separately set up in the setup page. Click on any meter to reset its peaks and overloads

manually. Hit “P” to reset peaks and overloads of all meters

7. Loudness meter:



Sum of all channels or loudness per channel.



Fully EBU R-128 compliant. This meter displays a bar-graph as well as the numerical value

LUFS (Loudness unit, Full scale, formerly known as LKFS).



In the setup page, you can select the time interval upon which you want to integrate

loudness (EBU-short, EBU-momentary or any time you want)



In the setup page, you can enable a peak hold feature. We enabled, the numerical value will

additionally display the letters “Pk :”, and the number won’t reset until you click on it.



Loudness Integrating Mode (Int) and Loundess Range (LRA) are effective when you your

measurement is running. You can control this using the 4 “Start”, “Pause”, “Reset” and

“Restart” buttons.



The value beside the Int and the LRA ones in parenthesis () represents the time during which

we've Integrated. Note that it’ll stop increasing when your signal is below the gate threshold

(which you can define in the setup page) A playback pause will therefore not affect the

MEASURED value. When the signal is gated, the word GATED is displayed as well.



Additionally, this meter displays a plot against time of its recent sum over all channels value.

This history graph is also piloted by the “Start”, “Pause”, “Reset” and “Restart” buttons.



Fully compatible with ATSC (Advanced Television Systems Committee) A/85.



Fully compatible with ITU-R 1770-1.



LUFS are the same unit as Dolby Dialnorm™ unit, and you will therefore get the same results

as long as Dolby's automatic speech detection is disabled.



LUFS are exactly the same unit as LKFS. EBU R-128 however prefers the name LUFS.



Setup page :



Can be accessed simply by clicking the “Setup” button on top right of the window, near the

“x” button for closing the window (note the “Metering” button which allows you to come back

to the main Final Check window.) In the setup page use the “Enable” buttons of each section

allow you to show or hide a given meter. More details to the different controls in user

manual.
