Instance Attribute Summary

• #algorithm ⇒ String

  Choose one of the following audio normalization algorithms: ITU-R BS.1770-1: Ungated loudness.

• #algorithm_control ⇒ String

  When set to correctAudio the output audio is corrected using the chosen algorithm.

• #peak_calculation ⇒ String

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

• #peak_limiter_threshold ⇒ Float

  Peak limiter threshold in decibels relative to true peak (dBTP) if TRUE_PEAK is enabled.

• #target_lkfs ⇒ Float

  Target LKFS(loudness) to adjust volume to.

Instance Attribute Details

#algorithm ⇒ String

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.

  include Aws::Structure
end

#algorithm_control ⇒ String

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.

Returns:

• (String)

# File 'lib/aws-sdk-medialive/types.rb', line 588

class AudioNormalizationSettings < Struct.new(
  :algorithm,
  :algorithm_control,
  :target_lkfs,
  :peak_calculation,
  :peak_limiter_threshold)
  SENSITIVE = []
  include Aws::Structure
end

#peak_calculation ⇒ String

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

Returns:

• (String)

# File 'lib/aws-sdk-medialive/types.rb', line 588

class AudioNormalizationSettings < Struct.new(
  :algorithm,
  :algorithm_control,
  :target_lkfs,
  :peak_calculation,
  :peak_limiter_threshold)
  SENSITIVE = []
  include Aws::Structure
end

#peak_limiter_threshold ⇒ Float

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.

Returns:

• (Float)

# File 'lib/aws-sdk-medialive/types.rb', line 588

class AudioNormalizationSettings < Struct.new(
  :algorithm,
  :algorithm_control,
  :target_lkfs,
  :peak_calculation,
  :peak_limiter_threshold)
  SENSITIVE = []
  include Aws::Structure
end

#target_lkfs ⇒ Float

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.
