ANS

Ambient noise suppression (ANS) recognizes and clears background noise to enhance the quality of recorded audio and user experience. This feature is better at suppressing continuous noise, such as rain sounds and other white noise .

Prerequisites

Before you implement the ANS feature, make sure that the following conditions are met:

• You have implemented Integrate the ZIM Audio SDK.
• You have implemented Implement online authentication.

Enable the feature

After the initialization, call the enableANS method to enable the feature.

// Enable the ANS feature.
ZIMAudio.getInstance().enableANS(true);

// Enable the ANS feature.
[[ZIMAudio sharedInstance] enableANS:YES];

// Enable the ANS feature.
ZIMAudio.sharedInstance().enableANS(true);

// Enable the ANS feature.
ZIMAudio.sharedInstance().enableANS(true);

After the feature is enabled, you can start recording audio files. For more information, see Send and receive audio messages.

(Optional) Set ANS parameters

To change the ANS mode after enabling the ANS feature by calling the enableANS method, call the setANSParam method.

ZIMAudioANSParam param = new ZIMAudioANSParam();
// Change the ANS mode to AGGRESSIVE.
param.mode = ZIMAudioANSMode.AGGRESSIVE;
ZIMAudio.getInstance().setANSParam(param);

ZIMAudioANSParam *param = [[ZIMAudioANSParam alloc] init];
// Change the ANS mode to ZIMAudioANSModeAggressive.
param.mode = ZIMAudioANSModeAggressive;
[[ZIMAudio sharedInstance] setANSParam:param];

// Change the ANS mode to aggressive.
ZIMAudio.getInstance().setANSParam({mode:ZIMAudioANSMode.aggressive});

// Change the ANS mode to aggressive.
ZIMAudioANSParam param = ZIMAudioANSParam(ZIMAudioANSMode.aggressive);
ZIMAudio.getInstance().setANSParam(param);
