+// This file is a snapshot of an AIDL file. Do not edit it manually. There are
+// two cases:
+// 1). this is a frozen version file - do not edit this in any case.
+// 2). this is a 'current' file. If you make a backwards compatible change to
+// the interface (from the latest frozen version), the build system will
+// prompt you to update this file with `m <name>-update-api`.
+//
+// You must not make a backward incompatible change to any AIDL file built
+// with the aidl_interface module type with versions property set. The module
+// type is used to build AIDL files in a way that they can be used across
+// independently updatable components of the system. If a device is shipped
+// with such a backward incompatible change, it has a high risk of breaking
+// later when a module using the interface is updated, e.g., Mainline modules.

+/**
+ * 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.
