# Audio HAL
Directory structure of the audio HAL related code.
Run `common/all-versions/copyHAL.sh` to create a new version of the audio HAL
based on an existing one.
## 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
its namespace and include path.
- `config` -- the XSD schema for the Audio Policy Manager
configuration file.
* `4.0` -- version 4.0 of the core HIDL API.
* ...
* `common` -- common types for audio core and effect HIDL API.
- `2.0` -- version 2.0 of the common types HIDL API.
- `4.0` -- version 4.0.
- ...
- `all-versions` -- code common to all version of both core and effect API.
- `default` -- shared code of the default implementation.
- `service` -- vendor HAL service for hosting the default
implementation.
- `test` -- utilities used by tests.
- `util` -- utilities used by both implementation and tests.
* `core` -- VTS tests and the default implementation of the core API
(not HIDL API, it's in `audio/N.M`).
- `7.0` -- code specific to version V7.0 of the core HIDL API
- `all-versions` -- the code is common between all versions,
version-specific parts are enclosed into conditional directives
of preprocessor or reside in dedicated files.
- `default` -- code that wraps the legacy API (from
`hardware/libhardware`).
- `vts` VTS tests for the core HIDL API.
* `effect` -- same for the effect HIDL API.
- `2.0`
- `config` -- the XSD schema for the Audio Effects configuration
file.
- `4.0`
- ...
- `all-versions`
- `default`
- `vts`
* `policy` -- Configurable Audio Policy schemes.
- `1.0` -- note that versions of CAP are not linked to the versions
of audio HAL.
- `vts` -- VTS tests for validating actual configuration files.
- `xml` -- XSD schemas for CAP configuration files.
