Sound options

By default, Zoom uses noise suppression and echo cancellation to improve the quality of the audio received by your microphone, but these audio filters can interfere with situations that require capturing the full range of audio. See Configuring professional audio settings for Zoom Meetings for details.

Video SDK uses the same technology to improve audio quality, but also supports the ability to turn off these filters to capture the original sound of the microphone, for example, to support the use of a high-quality microphone with built-in audio filters or to capture the full audio range without noise suppression. Capturing the microphone's original sound disables the background noise suppression feature.

Original sound

To enable original sound, set enableMicOriginalInput to true in the ZoomVideoSDKAudioSettingHelper class. The default setting is false.

ZoomVideoSDKAudioSettingHelper audioSettingHelper = ZoomVideoSDK.getInstance().getAudioSettingHelper();
audioSettingHelper.enableMicOriginalInput(true);

To disable, set enableMicOriginalInput to false.

audioSettingHelper.enableMicOriginalInput(false);

Auto-adjust microphone volume

By default, the SDK lets the OS manage microphone gain. Use enableAutoAdjustMicVolume on ZoomVideoSDKAudioSettingHelper to have the SDK adjust the mic gain automatically as the speaker moves closer to or further from the device.

val audioSettingHelper = ZoomVideoSDK.getInstance().audioSettingHelper
// Enable auto-adjust mic gain.
audioSettingHelper.enableAutoAdjustMicVolume(true)
// Check whether auto-adjust is currently on.
val isOn = audioSettingHelper.isAutoAdjustMicVolumeEnabled

ZoomVideoSDKAudioSettingHelper audioSettingHelper =
    ZoomVideoSDK.getInstance().getAudioSettingHelper();
// Enable auto-adjust mic gain.
audioSettingHelper.enableAutoAdjustMicVolume(true);
// Check whether auto-adjust is currently on.
boolean isOn = audioSettingHelper.isAutoAdjustMicVolumeEnabled();

Auto-adjust is incompatible with original sound. Original sound disables the SDK's processing, including automatic gain control. Pick one based on your use case.
