Calibrating the mic sound quality (Cleanup)

Here’s how to adjust the sound quality of the mic audio to make your voice sound listenable and clear.

This feature helps you to suppress ambient noise or to normalize the differences in volume between mics, for instance.

On the menu screen, click the “MIC CLEANUP” tab and set the parameters in the respective menus.

Menu		Value	Explanation
LOW CUT: This cuts out unneeded low-band audio.
LOW CUT		Off, On	Turns the low cut on/off.
LOW CUT		Flat–500Hz	Sets the frequency point from which the output is cut. The frequencies below the frequency point you set are cut.
NOISE SUPPRESSOR: This suppresses noises picked up from the surrounding environment by the mic.
NOISE SUPPRESSOR		Off, On	Switches the noise suppressor on/off.
TYPE		Sets the noise suppressor type.
		EXPANDER	Brings down the volume on sounds that are lower in volume than the threshold. This helps keep down white noise and other such sounds during silence.
		GATE	Suppresses sounds that are lower in volume than the threshold. This helps remove white noise and other such sounds during silence.
		ADAPTIVE	Analyzes the ambient sound to suppress unnecessary environmental noise.
LEVEL		-60–0dB (when using the expander)	Sets the threshold level at which the sound is reduced.
		-96–0dB When GATE is used	Specifies the level used as the threshold for suppressing audio.
		0–9 When ADAPTIVE is used	Sets the level for suppressing noise. Larger values suppress more noise. If you hear unwanted changes in the sound when using the noise suppressor, such as quieter audio or changes in sound quality, these issues may be resolved if you increase the input gain for the mic.
ATTACK		0–100ms When GATE is used	Sets how long it takes for the noise suppressor to be applied. The time is for reference only. This also changes depending on the volume.
RELEASE		0–4000ms (when using the expander)	Sets how long it takes for the noise suppressor effect to be cancelled. The time is for reference only. This also changes depending on the volume.
RELEASE		50–5000ms When GATE is used
DE-ESSER: Reduces sibilant noise (the sounds you hear when pronouncing “s” words and other hissing sounds).
DE-ESSER		Off, On	Turns the de-esser on/off.
DE-ESSER		1–10	Adjusts the intensity of the de-esser effect.
COMPRESSOR: Makes louder sounds quieter. This reduces the difference between the louder and softer sounds, making the audio more listenable.
COMPRESSOR		Off, On	Turns the compressor on/off.
LEGACY MODE		This selects the compressor type. The parameters displayed depend on the LEGACY MODE setting.
		Off	Simulates a compressor used in a recording studio.
		On	A regular compressor. The detailed parameters can be adjusted.
LEGACY MODE: Off
COMPRESSOR		0–127	Larger values cause the sound to be compressed.
GR (GAIN REDUCTION) meter		Displays the audio compression status.
ADVANCED		When this is on, you can set the PEAK REDUCTION and GAIN.
PEAK REDUCTION		0–100	Adjusts the degree of compression.
GAIN		0–100	Adjusts the final output volume level after applying the compressor.
LEGACY MODE: On
THRESHOLD		-48–0dB	Specifies the level used as the threshold at which the compressor is applied. Reduces the level of sounds that exceed the level you specify here.
RATIO		1.00:1– Inf:1	Sets the ratio at which the sound level is reduced, when it crosses the threshold. For example, if you set “RATIO” to “2.00:1”, audio levels that cross the threshold are reduced by 1/2.
ATTACK		0–100ms	Sets how long it takes for the compressor to be applied. The time is for reference only. This also changes depending on the volume.
RELEASE		50–5000ms	Sets how long it takes for the compressor to be cancelled. The time is for reference only. This also changes depending on the volume.
POST GAIN		+0–+30dB	Adjusts the final output volume level after applying the compressor.
EQ: This is a 10-band equalizer, which lets you adjust the volume for each frequency band.
EQ		Off, On	Turns the equalizer on/off.
Frequency characteristics graph		Displays the frequency characteristics of the input sound as a graph.
		Frequency band	Effect
		SUB BASS	Adds weight and thickness to your voice.
		BOOM	Adjusts the degree of muddiness in the sound.
		BROADCAST	Adjusts the clarity and solidity of the voice. By precisely controlling this frequency band, the voice recorded by microphone is optimized for broadcasting, bringing it closer to the clear, solid “broadcast voice” that’s like what you hear on the radio.
		NASAL	Sharpens the contour of the sound. Adjusts clangorous sounds or sounds that seem thin.
		PRESENCE & ESSES	Adjusts the brightness and coherence of the sound, as well as the sibilance.
		AIR	Adjusts the airiness of the sound.
ADVANCED		Off, On	When this is on, the frequency and gain values are shown. Also, you can set the Q (frequency bandwidth).
Frequency/gain		The frequency/gain of each band is shown as points. Drag and drop a point to set the frequency/gain. When “ADVANCED” is off, only four bands (2, 4, 7 and 10) can be set.
Frequency	Band 1	20–400Hz	Specifies the boost/cut center frequency for each frequency band.
	Bands 2–4	20–470Hz
	Bands 5–7	315Hz–3.3kHz
	Bands 8, 9	3.0–20.0kHz
	Band 10	800Hz–20.0kHz
Gain	Bands 1–10	-12–+12	Sets the amount of boost/cut for each frequency band.
Q		0.3–16.0	Adjusts the bandwidth used for boosting or attenuating each frequency band. This setting is available when the “ADVANCED” switch is enabled.
