Menu List
Menu item Value (bold text: default value) Explanation
Lo Freq 20.0Hz– 100Hz –2.00kHz Adjusts the center frequency when changing the tone quality in the low band.
Compressor/Limiter OFF , ON Turns the compressor or limiter on/off.
Type
Selects the compressor or limiter.
Compressor Effect
Audio that exceeds the specified threshold level is compressed. This reduces the difference
between the maximum volume and minimum volume, making the audio more comfortable
for listening
Limiter
Effect Compresses the audio so that the mixed audio does not exceed the specified threshold level.
* Distortion will occur if audio that exceeds the allowable range of the limiter is input.
Compressor
Threshold -50– -8 –0dB
Specifies the level used as the threshold at which the compressor is applied. Compression is
applied to audio that exceeds the threshold.
Ratio
1.00: 1, 1.12: 1, 1.25: 1, 1.40: 1,
1.60: 1, 1.80: 1, 2.00: 1,
2 .50: 1 ,
3.20: 1, 4.00: 1, 5.60: 1, 8.00: 1,
16.0: 1, INF: 1
Specifies the degree of compression applied to the audio. The state in which no compression
is applied is defined as “1”.
Attack 0.0– 30 –100ms Specifies the time until compression starts when audio exceeding the threshold is input.
Release 30– 250 –5000ms Adjusts the length of time until compression ends after audio falls below the threshold.
Makeup Gain -40– 0 –40dB Adjusts the final output volume level after applying the compressor.
Limiter
Threshold -40– -6 –0dB
Adjusts the level that becomes the threshold at which the limiter is applied. Compression
is applied to audio that exceeds the threshold. The volume level of audio that is output is
limited so as to stay to below the threshold.
Loudness Auto Gain
Control
OFF , ON
Turns loudness auto gain control on/off.
Effect
The long-term average loudness is measured, and the volume is adjusted so that it is
appropriate overall.
Integrated Gain
Control
Disable, Enable
Specifies whether the extended interval auto control is enabled (Enable) or disabled
(Disable).
Sens 0– 80 –127 Adjusts the speed at which the target level (Target LKFS) is approached.
Momentary Gain
Control
Disable, Enable Specifies whether the momentary auto control is enabled (Enable) or disabled (Disable).
Sens 0– 80 –127 Adjusts the speed at which the target level (Target LKFS) is approached.
Target LKFS -34– -24 –-10dB Specifies the target loudness value.
Adaptive Noise
Reduction
OFF , ON
Turns Adaptive Noise Reduction on/off.
Effect
By continuously monitoring the input audio to detect noise during periods of silence, this
removes only the noise component.
Depth 0– 80 –127 Specifies the strength at which noise reduction is applied.
Talking Detector 0– 80 –127
Specifies the sensitivity of the talking detector.
Higher values raise the sensitivity, so that it will be easier to detect the presence or absence
of talking even in a noisy environment.
Auto Learn Disable, Enable Enables automatic noise detection.
Manual Measure Exec Performs noise detection manually.
Forget Learning Exec
Resets the learned parameters.
Reset applies to the parameters of both adaptive noise reduction and loudness auto gain
control.
Lo Frequency Cut OFF , ON Turns Lo Frequency Cut on/off.
