title: Effect name and options
description:
If the effect name is "analysis" then it does not run any effect. Instead, it analyzes the audio to determine a normalized gain level. The results are put into the level, peak, and gain properties as well as this effect property as the parameter to the vol effect.
type: string
readonly: no
required: no
format: effect [options]
title: Normalization level
description:
Normalize the volume to the specified amplitude. The normalization may be indicated as a floating point value of the relative volume with 1.0 being maximum. The normalization may also be indicated as a numeric value with the suffix "dB" to set the amplitude in decibels.
type: string
readonly: no
required: no
default: -12dBFS
title: Signal power level (RMS)
type: float
readonly: yes
required: no
title: Peak signal level
type: float
readonly: yes

title: Gain to normalize
type: float
readonly: yes
required: no
title: Use peak
description:
Use peak signal level instead of RMS (root mean square) power level to compute gain for normalization.
type: integer
readonly: no
required: no
minimum: 0
maximum: 1
default: 0
widget: checkbox
title: Dynamic normalization
description:
This computes the gain for normalization dynamically per frame, but it uses a sliding smoothing window to prevent the gain from fluctuating wildly. Currently, this must be used in combination with some SoX effect.
type: integer

minimum: 0

Deprecated. See normalize

title: Maximum gain
description:
With dynamic normalization, this puts a maximum limit on the amount of gain.
type: float
