AfpGenerator 5.0.12 API

All Implemented Interfaces:
```
public final class AfpGenerator

                    
```
AfpGenerator is responsible for handling audio recording from the microphone, and generating AFP (Audio Fingerprint) data.
This class manages the lifecycle of audio recording, including starting and stopping the recording process, buffering audio data, detecting silence, and invoking callbacks to notify listeners of recording events and AFP generation results.
