Class AttributesEstimator

java.lang.Object

net.idrnd.voicesdk.common.VoiceSdkNativePeer

net.idrnd.voicesdk.attributes.AttributesEstimator

All Implemented Interfaces:

java.lang.AutoCloseable

public class AttributesEstimator
extends VoiceSdkNativePeer

Performs the estimation of Attributes from the supported set in provided audio data.

This class serves as gateway to native Voice SDK implementation and allocates resources on native heap. To release the allocated memory, AutoCloseable.close() method should be invoked when the instance is no longer needed.

Any method that delegates to native call may throw VoiceSdkEngineException
