Audio Normalization Settings

CONSTRUCTOR

IMPORTING

Optional arguments:

iv_algorithm TYPE /AWS1/MDLAUDIONORMALIZATIONALG /AWS1/MDLAUDIONORMALIZATIONALG

Choose one of the following audio normalization algorithms:

ITU-R BS.1770-1: Ungated loudness. A measurement of ungated average loudness for an entire piece of content, suitable for measurement of short-form content under ATSC recommendation A/85. Supports up to 5.1 audio channels.

ITU-R BS.1770-2: Gated loudness. A measurement of gated average loudness compliant with the requirements of EBU-R128. Supports up to 5.1 audio channels.

ITU-R BS.1770-3: Modified peak. The same loudness measurement algorithm as 1770-2, with an updated true peak measurement.

ITU-R BS.1770-4: Higher channel count. Allows for more audio channels than the other algorithms, including configurations such as 7.1.

iv_algorithmcontrol TYPE /AWS1/MDLAUDIONORMALIZATIONA00 /AWS1/MDLAUDIONORMALIZATIONA00

When set to correctAudio the output audio is corrected using the chosen algorithm. If set to measureOnly, the audio will be measured but not adjusted.

iv_targetlkfs TYPE /AWS1/RT_DOUBLE_AS_STRING /AWS1/RT_DOUBLE_AS_STRING

Target LKFS(loudness) to adjust volume to. If no value is entered, a default value will be used according to the chosen algorithm. The CALM Act recommends a target of -24 LKFS. The EBU R-128 specification recommends a target of -23 LKFS.

iv_peakcalculation TYPE /AWS1/MDLAUDIONORMPEAKCALC /AWS1/MDLAUDIONORMPEAKCALC

If set to TRUE_PEAK, calculate the TruePeak for each output's audio track loudness.

iv_peaklimiterthreshold TYPE /AWS1/RT_DOUBLE_AS_STRING /AWS1/RT_DOUBLE_AS_STRING

Peak limiter threshold in decibels relative to true peak (dBTP) if TRUE_PEAK is enabled. If TRUE_PEAK is not enabled a full scale (dbFS) value is used. The peak inter-audio sample loudness in your output will be limited to the value that you specify, without affecting the overall target LKFS. Leave blank to use the default value 0.
