Values.AudioNormalizationSettingsSourceAdvanced audio normalization settings. Ignore these settings unless you need to comply with a loudness standard.
type nonrec t = {algorithm : AudioNormalizationAlgorithm.t option;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.
*)algorithmControl : AudioNormalizationAlgorithmControl.t option;When enabled the output audio is corrected using the chosen algorithm. If disabled, the audio will be measured but not adjusted.
*)correctionGateLevel : int option;Content measuring above this level will be corrected to the target level. Content measuring below this level will not be corrected.
*)loudnessLogging : AudioNormalizationLoudnessLogging.t option;If set to LOG, log each output's audio track loudness to a CSV file.
*)peakCalculation : AudioNormalizationPeakCalculation.t option;If set to TRUE_PEAK, calculate and log the TruePeak for each output's audio track loudness.
*)targetLkfs : float option;When you use Audio normalization, 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. If you choose algorithm 1770-1, the encoder will choose -24 LKFS; otherwise, the encoder will choose -23 LKFS.
*)truePeakLimiterThreshold : float option;Specify the True-peak limiter threshold in decibels relative to full scale (dBFS). The peak inter-audio sample loudness in your output will be limited to the value that you specify, without affecting the overall target LKFS. Enter a value from 0 to -8. Leave blank to use the default value 0.
