only contain channel counts where the routing includes at least one stereo and one

surround stream.

With the number of channels selected, select the radio buttons next to the desrired

stereo source and surround target.

4. New File. With this radio button selected, files will be upmixed to a new file.

Loudness

This tab allows you to configure all of the options related to analysis and correction of

loudness parameters.

1. Auto-correct Check this option to auto-correct the files to the specifications into the

‘Correct into folder’ which is specified on the ‘File Handling’ tab.

2. Verify Checks the corrected file for conformity. This requires another scan, creating

the possibility for an iterative process to exactly meet all requirements.

3. Display options. The left column of tick-boxes allows you to choose which items

are displayed in the analysis summary of the process queue. Note that only LRA is

available from the Dynamics Adaptation section unless you have a DynApt™ license

and DynApt™ processing is turned on.

4. Specifications. The specification options are in the second column and allow you

to choose which criteria you wish to test for. If these tick-boxes are ticked, then

incoming audio is compared against the corresponding values and will pass or fail as

appropriate.

(a) Algorithm In this area the fundamental analysis algorithm is selected, governing

all loudness calculations made by this instance of AMB. AMB is capable of

performing calculations compliant with ITU-R BS. 1770-1, ITU-R BS. 1770-2/3

EBU R128 (2010)

, EBU R128 (EBU mode), Dialog Gate & Leq(m). Current

loudness standards are based around these algorithms eg. ATSC A/85, ARIB

TR-B32, AGCOM 219/9/CSP etc. although many delivery specifications simply

refer to the algorithm directly.

Our implementation of the ITU-R BS.1770-3 algorithm is also ITU-R BS.1770-2 compliant, so you can use this

setting to cover both requirements

The EBU R128 (2010) algorithm is a legacy setting. This uses the G8 gating system superseded by the G10

gate in the current EBU R128 algorithm.
