 Directory structure of the audio HAL related code.
 
-## Directory Structure for AIDL audio HAL
+Run `common/all-versions/copyHAL.sh` to create a new version of the audio HAL
+based on an existing one.
 
-The AIDL version is located inside `aidl` directory. The tree below explains
-the role of each subdirectory:
-
-* `aidl_api` — snapshots of the API created each Android release. Every
-  release, the current version of the API becomes "frozen" and gets assigned
-  the next version number. If the API needs further modifications, they are
-  made on the "current" version. After making modifications, run
-  `m <package name>-update-api` to update the snapshot of the "current"
-  version.
-* `android/hardware/audio/common` — data structures and interfaces shared
-  between various HALs: BT HAL, core and effects audio HALs.
-* `android/hardware/audio/core` — data structures and interfaces of the
-  core audio HAL.
-* `default` — the default, reference implementation of the audio HAL service.
-* `vts` — VTS tests for the AIDL HAL.
-
-## Directory Structure for HIDL audio HAL
-
-Run `common/all-versions/copyHAL.sh` to create a new version of the HIDL audio
-HAL based on an existing one. Note that this isn't possible since Android T
-release. Android U and above uses AIDL audio HAL.
+## Directory Structure
 
 * `2.0` — version 2.0 of the core HIDL API. Note that `.hal` files
   can not be moved into the `core` directory because that would change
