These plug-ins are Consumers only and are used to probe the audio signal at any point in the signal processing chain.

Dialnorm Meter Configuration

Variants are available to support the following audio leg group types:

Mono	Stereo	5.1

The Dialnorm meter plugin computes the speech-gated integrated loudness (Dolby Dialnorm).

For this plugin, you need to set the LUFS/LKFS units to use in the Network-Plug-in’s Mixer settings.

Dialog Detect	Select the channels in which the speech Dialnorm measurement should be made. C: Only the center channel, LRC: Left, right and center channels. LR: Left and right channels, L: Only the left channel, R: Only the right channel This selection is only available in the 5.1 plugin version. In Stereo mode, the detection is always performed on the sum of the left and right channels.

Real Time Analyzer Configuration

Variants are available to support the following audio leg group types:

Mono	Stereo	5.1

This plugin measures the frequency spectrum of a signal with a 12 bins/octave resolution.

info The Real Time Analyzer actually is a Mono Process but uses a 5.1 Input. For Mono and Stereo use, it must be routed accordingly (Mono → Centre, and Stereo → Left /Right)

Preset	The configuration of a SAME Application can be memorized as a preset for instant recall. See SAME_ SAME Application Preset Configuration.
Analyze	Set the channel to analyze. ITU 5.1 to Mono: (Left + Right) / sqrt(2) + Center + (Ls + Rs)/2, ITU Surround 5.1 to Mono downmix ITU L/R to Mono: (Left + Right) / sqrt(2), ITU Stereo to Mono downmix L minus R: (Left - Right) / sqrt(2) ITU LRC to Mono: (Left + Right) / sqrt(2) + Center, ITU LRC to Mono downmix ITU Ls/Rs to Mono: (Ls + Rs) / sqrt(2), ITU Stereo to Mono downmix Left: Left Right: Right Center: Center LFE: Low Frequency Effect Ls: Left surround Rs: Right surround
Listen	Set the signal to monitor. Input: Listen to the analyzer’s input. Analyzer Downmix: Listen to the downmix, as selected in Analyze.
Scale	Set the measurement scale. IEC-268-18 Linear -60 to 0 dBFS

Silence Detector Configuration

Variants are available to support the following audio leg group types:

Mono	Stereo	5.1

This plugin detects when a signal is below a threshold for a given amount of time.

Preset	The configuration of a SAME Application can be memorized as a preset for instant recall. See SAME_ SAME Application Preset Configuration.
Reset	Click to reset the silence alarm.
Trigger Level	Set the threshold below which a signal is considered to be silence.
Detection Filters	Set the frequency range used to detect sound energy levels that are used for silence detection. The high-pass filter is useful to eliminate hum from masking silence. The low-pass filter is useful to eliminate hiss from masking silence. Click and drag HP or LP to set the filter’s cut-off frequencies.
Time to Alarm	Set the minimum amount of silence time required to trigger the alarm.
Last Silence Count-down timer	Shows how much time has passed since the last silence alarm was triggered. Shows a count-down timer that starts with the value set by Time to Alarm. If this count-down timer gets to zero, a silence alarm is triggered.

Line Identification Analyzer / Shuffler

Variants are available to support the following audio leg group types:

Mono	Stereo	5.1

This plugin analyzes and detects line identification tone bursts, according to:

EBU R49 (Two channel audio identification).
BLITS (Black and Lanes’ Ident Tones for Surround).
EBU multichannel identification signal.
GLITS (Graham's Line Identification Tone System).

This plugin is intended to be used with the Line Identification Generator as a signal source. See SAME_ Generators & Players.

It also includes functionality to automatically delay the channels to align them, and to invert the phase of the channels that have been detected out of phase.

This plugin can then automatically reorder multichannel legs.

Preset	The configuration of a SAME Application can be memorized as a preset for instant recall. See SAME_ SAME Application Preset Configuration.
Bypass	Set to bypass this plugin's operation.
Start Over	Click to clear all test measurements.
Line ID	Shows the current detection state. Idle: No test measurement has been started. Detecting: The test measurement has started. Completed: The test measurements have completed.
Level	Shows the detected channel level.
Adjustment	Set the amount of gain (boost or cut) needed to equalize the signal levels between channels.
Phase	Shows the phase measurement for the channel. Stereo: with regard to the left channel. Surround 5.1: with regard to the phase of the earliest arriving channel.
Adjustment Ø	Click to invert the phase by 180°.
Delay	Set the amount of delay to apply to the channel. Click the up / down buttons and drag your mouse up or down to set the delay.
Ref	Set the reference signal level.
Adjustment	Set the amount of delay to apply to the channel.
Alignment Level	Suggested channel gain required to achieve the Alignment Level.
Select Corrections	Once the Line ID tests have completed, corrections that can be applied are shown as necessary. Level: Adjust the signal level to equalize all channels according to the test. Phase: Correct the channels with phase inversion according to the test, by 0° or 180°. Stereo phasing is with regard to the left channel. Surround 5.1 phasing is with regard to the phase of the first channel used by the test sequence. Delay: Adjust the time alignment delay according to the test, up to 1 second. Order: Reorder the outputs to the proper order according to the test.
Peak Hold	Click to set the level meter peak hold mode. No hold: Shows sound levels. Transient peaks are not frozen. Temp hold: Shows sound levels while also freezing the display of the highest instantaneous peaks for a short period. Cont. hold: Shows sound levels while also freezing the display of the highest instantaneous peaks. Click RESET ALL to clear the peak signal display on all level meters.
Reset	Reset the level meter's peak hold measurement.

There are two ways to shuffle the channels by:

Dragging and dropping the channel to its new position.
By using your mouse / pointer to move a channel left or right.
