  - identifier: argument
    title: Gain
    type: string
    description: |
                 The gain may be indicated as a floating point value of the gain adjustment.
                 The gain may also be indicated as a numeric value with the suffix "dB" to adjust in terms of decibels.
                 The gain may also be set to "normalise" to normalise the volume to the target amplitude -12dBFS.
  - identifier: window
    title: Window
    type: integer
    description: The number of video frames over which to smooth normalisation.
    default: 75
    mutable: yes
  - identifier: normalise
    title: Normalise
    type: string
    description: |
                 Normalise the volume to the specified amplitude.
                 The normalization may be indicated as a floating point value of the relative volume.
                 The normalisation may also be indicated as a numeric value with the suffix "dB" to set the amplitude in decibels.
    default: -12dBFS
    mutable: yes
  - identifier: limiter
    title: Limiter
    type: string
    description: |
                 Limit all samples above the specified amplitude.
                 The limiting may be indicated as a floating point value of the relative volume.
                 The limiting may also be indicated as a numeric value with the suffix "dB" to set the limiting amplitude in decibels.
    default: -6dBFS
    mutable: yes
  - identifier: max_gain
    title: Max gain
    type: string
    description: A floating point or decibel value of the maximum gain that can be applied during normalisation.
    default: 20dB
    mutable: yes
  - identifier: end
    title: End gain
    type: string
    description: A gain value just like the Gain property. This causes the gain to be interpolated from 'gain' to 'end' over the duration.
    mutable: yes
