+/**
+ * The Audio Eraser Effect is an audio effect that combines multiple capabilities to manipulate and
+ * enhance audio streams.
+ *
+ * The Audio Eraser Effect integrates three primary components:
+ *
+ * Sound Separator: Detects and splits the input audio into multiple sound sources.
+ * Sound Classifier: Classifies each separated sound source into predefined categories based on the
+ * AudioSet ontology.
+ * Remixer: Adjusts the gain factor (volume) of each classified sound source according to specified
+ * configurations, then recombines them into a single output audio stream.
+ *
+ * The Audio Eraser Effect operates in different modes, each leveraging a subset of these
+ * components to achieve specific functionalities as defined in `android.media.audio.eraser.Mode`.
+ *
+ * Flow Diagrams for each operation mode as below.
