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.


  1. 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.
    Flat–500 Hz

    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

    -96–0 dB

    When GATE is used

    Specifies the level used as the threshold for suppressing audio.

    0–9

    When ADAPTIVE is used

    Set 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.
    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 -48–0 dB

    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 0–100 ms

    Sets how long it takes for the compressor to be applied.

    • Times are approximate. This also changes depending on the volume.
    RELEASE 50–5000 ms

    Sets how long it takes for the compressor effect to be cancelled.

    • Times are approximate. This also changes depending on the volume.
    POST GAIN +0–+30 dB Adjusts the final output volume level after applying the compressor.
    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.
    1–10

    Adjusts the intensity of the de-esser effect.
    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.
