# Auto Gain

PulseEffects auto gain is based on the library libebur128. It changes the audio volume to a perceived loudness level that can be tweaked by the user.

# Target

Loudness level.

# Reset

Resets the auto gain history.

# Detect Silence

When the momentary loudness is below the relative we assume the audio material is passing through a brief moment of silence and no changes to the output gain are applied. If you do not want this behavior disable the silence detection.

# Use Geometric Mean

The estimated loudness is obtained from the geometric mean of the momentary, short-term and integrated loudness. When this option is disabled a weighted average is used.

# Momentary

Controls how much the momentary term will influence the loudness level estimation.

# Short Term

Controls how much the short term measure will influence the loudness level estimation.

# Integrated

Controls how much the integrated term will influence the loudness level estimation.

# Relative

Relative threshold. It is used to detect silence. Whenever the momentary term is below this threshold modifications to the output gain will be disabled.

# Loudness

Estimated input loudness. The difference between its value and the target loudness determines the output gain.

# Range

Loudness range. Indicates how large is the material dynamic range.

# Усиление

Output gain value. The input signal will be multiplied by this correction gain to bring its loudness to the target value.
