AudioNormalizationSettings class
Advanced audio normalization settings. Ignore these settings unless you need to comply with a loudness standard.

Properties
- algorithm → AudioNormalizationAlgorithm?
-
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.

When enabled the output audio is corrected using the chosen algorithm. If
disabled, the audio will be measured but not adjusted.
final
- correctionGateLevel → int?
-
Content measuring above this level will be corrected to the target level.
Content measuring below this level will not be corrected.
final
- hashCode → int
-
The hash code for this object.

-
If set to LOG, log each output's audio track loudness to a CSV file.
final
- peakCalculation → AudioNormalizationPeakCalculation?
-
If set to TRUE_PEAK, calculate and log the TruePeak for each output's audio
track loudness.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- targetLkfs → double?
-
When you use Audio normalization (AudioNormalizationSettings), optionally
use this setting to specify a target loudness. If you don't specify a value
here, the encoder chooses a value for you, based on the algorithm that you
choose for Algorithm (algorithm). If you choose algorithm 1770-1, the
encoder will choose -24 LKFS; otherwise, the encoder will choose -23 LKFS.
