Option Description
Trim Level
The audio level of each incoming source can be trimmed down and adjusted to
reduce the input level of overdriven sources, or for personal tastes. Input a value
between 0 and 100. Optionally, the keyboard up and down arrow keys can be
used to increment and decrement each value by 1.
Noise Gate
Noise Gate: Eliminate sounds below a set sound level, commonly used with
microphones to minimize unwanted background noise.
• Enable/Disable: Enables or disables the noise gate.
• Threshold: Set the threshold (dB) where audio below the set value will close
the noise gate. Values are between -96 to 0.
• Attack: Set the amount of time (ms) it takes to fully open the noise gate once
audio has been detected and is above the threshold value. The noise gate will
be opened linearly (faded up) across the time value set. Values are between
10 to 500
• Hold: Set the minimum amount of time (ms) that the audio source needs to
be below the threshold value for the noise gate to be released. Values are
between 10 to 500.
• Release: Set how slowly (ms) the noise gate is closed once audio has fallen
below the threshold and the hold time value is reached. The noise gate will be
closed linearly (faded down) across the time value set. Values are between 10
to 2000.
Auto-Gain
Auto-Gain: Automatically amplies (increases) or attenuates (decreases) the
audio volume level of a source’s input signal to achieve a comfortable audio
listening level. This is separate from trim that reduces the entire audio signal
level.
• Enable/Disable: Enables or disables the auto-gain.
• Threshold: Set the minimum threshold (dB) level for an audio signal that
is needed to activate amplication. This ensures that amplication is not
applied to noise when there is no active audio. Values are between -36 to -20.
• Target Level: Set the target audio level (dB) that auto-gain will use to
determine when to activate amplication or attenuation. Values are between
-18 to -3.
• Max Attenuation: Sets the maximum level of attenuation (dB) that can be
removed from a source audio signal when it is above the target level. Values
are between 11 to 18.
• Max Gain: Sets the maximum level of amplication (dB) that can be added
to a source audio signal when it is below the target level and above the
threshold. Values are between 0 to 15.
