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.
		Off, On	Turns the low cut on/off.
		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.
		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		-96–0dB When GATE is used	Specifies the level used as the threshold for suppressing audio.
LEVEL		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	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		50–5000ms	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.
DE-ESSER		Reduces sibilant noise (the sounds you hear when pronouncing “s” words and other hissing sounds).
		Off, On	Turns the de-esser on/off.
		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.
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.
DETAIL		Off, On	When this is on, you can set the center frequency and the Q (the frequency bandwidth).
Gain (vertical sliders)		-12–+12	Sets the amount of boost/cut for each frequency band.
Frequency (horizontal sliders)	Band 1	20–400Hz	Specifies the boost/cut center frequency for each frequency band. This setting is available when the “DETAIL” switch is enabled.
	Bands 2–4	20–470Hz
	Bands 5–7	315Hz–3.3kHz
	Bands 8, 9	3.0–20.0kHz
	Band 10	800Hz–20.0kHz
Q		0.3–16.0	Adjusts the bandwidth used for boosting or attenuating each frequency band. This setting is available when the “DETAIL” switch is enabled.
