+/**
+ * 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.

 This folder contains a skeleton audio control HAL implementation in Rust to
 demonstrate  how vendor may implement a Rust audio control HAL. To run this
 audio control HAL, include

+`android.hardware.automotive.audiocontrol-rust-service` in your image.
 
 This implementation returns `StatusCode::UNKNOWN_ERROR` for all operations
 and does not pass VTS/CTS. Vendor must replace the logic in

+# Rust Skeleton EVS HAL implementation.
+
+WARNING: This is not a reference EVS HAL implementation and therefore does not
+provide any actual functionality.
+
+This folder contains a skeleton EVS HAL implementation in Rust to demonstrate
+how vendors could implement their EVS HAL in Rust. To compile and run this
+implementation, please include below package to the device build script:
+
+* `android.hardware.automotive.evs-aidl-rust-service`
+
+Please note that this service will attempt to register the service as
+`IEvsEnumerator/rust/0` and therefore is also required to be declared in the
+service context by adding below line to a proper `service_contexts` file:
+
+> android.hardware.automotive.evs.IEvsEnumerator/rust/0 u:object_r:hal_evs_service:s0
+
+This implementation intentionally returns `binder::StatusCode::UNKNOWN_ERROR`
+for any API call except deprecated API for ultrasonics; the process will be
+panicked on these methods instead. Hence, this implementation does not comply
+with VTS tests and vendors must replace each method with actual implementation.

-// 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.

+// 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.
