ANC Overview

Use DeviceANCAPI to read and control the connected device's Active Noise Cancellation settings.

What You Can Do​

  • Read and change the current ANCMode.
  • Read and change the ANC gain and transparency gain.
  • Read and change the ANC fade setting.

ANC Modes​

ModeDescription
.unknownThe device did not report a recognized ANC mode. Treat this as unavailable state rather than a selectable mode.
.normalNormal listening with noise cancellation off.
.ancActive Noise Cancellation.
.transparencyTransparency mode, which allows surrounding sound to pass through.

The public SDK does not define a Smart ANC mode. Only present modes supported by the connected device and your product specification.

Gain Values​

The current SDK Demo presents ANC and transparency gains on a 0...100 slider. The public protocol currently exposes these values as Int/NSNumber without documenting a universal range or unit. Until the SDK publishes that contract, treat 0...100 as the current Demo integration convention rather than a guarantee for every device.
