<!-- List of effect libraries to load.
|
|
Each library element must contain a "name" attribute and a "path" attribute giving the
|
|
name of a library .so file in /vendor/lib/soundfx on the target
|
|
|
|
If offloadable effects are present, the AOSP library libeffectproxy.so must be listed as
|
|
well as one library for the SW implementation and one library for the DSP implementation:
|
|
<library name="proxy" path="libeffectproxy.so"/>
|
|
<library name="some_fx_sw" path="lib_some_fx_sw.so"/>
|
|
<library name="some_fx_hw" path="lib_some_fx_hw.so"/>
|
|
|
|
If the audio HAL implements support for AOSP software audio pre-processing effects,
|
|
the following library must be added:
|
|
<library name="pre_processing" path="libaudiopreprocessing.so"/>
|
|
-->
|
|
<libraries>
|
|
<library name="bundle" path="libbundlewrapper.so"/>
|
|
<library name="reverb" path="libreverbwrapper.so"/>
|
|
<library name="visualizer" path="libvisualizer.so"/>
|

<library name="downmix" path="libdownmix.so"/>
|
|
<library name="loudness_enhancer" path="libldnhncr.so"/>
|

<library name="dynamics_processing" path="libdynproc.so"/>

<library name="haptic_generator" path="libhapticgenerator.so"/>

<!-- list of effects to load.
|
|
Each "effect" element must contain a "name", "library" and a "uuid" attribute.
|
|
The value of the "library" element must correspond to the name of one library element in
|
|
the "libraries" element.
|
|
The "name" attribute is indicative, only the value of the "uuid" attribute designates
|
|
the effect.
|
|
The uuid is the implementation specific UUID as specified by the effect vendor. This is not
|
|
the generic effect type UUID.
|
|
|
|
Offloadable effects are described by an "effectProxy" element which contains one "libsw"
|
|
element containing the "uuid" and "library" for the SW implementation and one "libhw"
|
|
element containing the "uuid" and "library" for the DSP implementation.
|
|
The "uuid" value for the "effectProxy" element must be unique and will override the default
|
|
uuid in the AOSP proxy effect implementation.
|
|
|
|
If the audio HAL implements support for AOSP software audio pre-processing effects,
|
|
the following effects can be added:

<!-- Audio pre processor configurations.
|
|
The pre processor configuration is described in a "preprocess" element and consists in a
|
|
list of elements each describing pre processor settings for a given use case or "stream".
|
|
Each stream element has a "type" attribute corresponding to the input source used.
|
|
Valid types are:
|
|
"mic", "camcorder", "voice_recognition", "voice_communication"
|
|
Each "stream" element contains a list of "apply" elements indicating one effect to apply.
|
|
The effect to apply is designated by its name in the "effects" elements.
|
|
|
|
<preprocess>
|
|
<stream type="voice_communication">

|
<apply effect="aec"/>

|
<!-- Audio post processor configurations.
|
|
The post processor configuration is described in a "postprocess" element and consists in a
|
|
list of elements each describing post processor settings for a given use case or "stream".
|
|
Each stream element has a "type" attribute corresponding to the stream type used.
|
|
Valid types are:
|
|
"music", "ring", "alarm", "notification", "voice_call"
|
|
Each "stream" element contains a list of "apply" elements indicating one effect to apply.
|
|
The effect to apply is designated by its name in the "effects" elements.

<!-- Device pre/post processor configurations.
|
|
The device pre/post processor configuration is described in a deviceEffects element and
|
|
consists in a list of elements each describing pre/post proecessor settings for a given
|
|
device or "devicePort".
|
|
Each devicePort element has a "type" attribute corresponding to the device type (e.g.
|
|
speaker, bus), an "address" attribute corresponding to the device address and contains a
|
|
list of "apply" elements indicating one effect to apply.
|
|
If the device is a source, only pre processing effects are expected, if the
|
|
device is a sink, only post processing effects are expected.
|
|
The effect to apply is designated by its name in the "effects" elements.
|
|
The effect will be enabled by default and the audio framework will automatically add
|
|
and activate the effect if the given port is involved in an audio patch.
|
|
If the patch is "HW", the effect must be HW accelerated.
