* Add property to ignore audio effects on the platformJean-Michel Trivi2015-06-221-0/+1
| | | | | | | | | Use boolean property ro.audio.ignore_effects to load or ignore the audio effects. Bug 21906334 Change-Id: I778f8b10a1caf25f7679705b1c83775223df011d
* fix deadlock issues that arise when there are simultaneousjpadmana2014-01-311-1/+27
| | | | | | | | | | | | | | | | | | | effect control interface calls to proxy and to non sub-effect wrappers(eg., bundlewrapper) from audioflinger Also, return NO_ERROR when CMD_OFFLOAD succeeds Whenever there are parallel calls to proxy and non sub-effects wrappers, some of the calls are not completed. This is due to deadlock arsing out of Proxy waiting for the subeffect call to return and subeffect waiting for proxy to release lock. The call flow is changed to a cleaner and simple one - Proxy gets the aeli(effect library info) of subeffects during the EffectGetSubEffects() call. Therby, proxy will manage the sub effects by itself rather than going through effects factory.

* Effects Factory changes for effects offloadjpadmana2013-09-271-0/+19
| | | | | | | | | | | | | | | | | | | | | | audio_effects.conf - commented changes to illustrate the addition of Proxy and sub effects to the conf file Added an effectFactoryApi - EffectGetSubEffects for querying the sub effect descriptors from the factory. This api is used by the Proxy to get the sub effects Added functions and data structures in factory code for loading the sub effects gSubEffectList - has the Proxies and their corresponding sub effects - addSubEffect() - reads a sub effect node and adds to the gSubEffectList - findSubEffect() - searches through the gSubEffectList to find a SubEffect Bug: 8174034.

* Audio framework: support for audio pre processingEric Laurent2011-07-181-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | Audio effect framework is extended to suport effects on output and input audio path. AudioFlinger: Support for audio effects and effect chains is moved from PlaybackThread class to ThreadBase class so that RecordThread can manage effects. Effects of type pre processing are allowed on record thread only. When a pre processing is enabled, the effect interface handle is passed down to the input stream so that the audio HAL can call the process function. The record thread loop calls the effect chain process function that will only manage the effect state and commands and skip the process function. AudioRecord: The audio session is allocated before calling getInput() into audio policy serice so that the session is known before the input theead is created and pre processings can be created on the correct session. AudioPolicyService: default pre processing for a given input source are loaded from audio_effects.conf file. When an input is created, corresponding effects are created and enabled.

* New effect library APIEric Laurent2011-05-271-6/+12
| | | | | | | | | | | | | | | | | Moved and renamed media/EffectApi.h to hardware/audio_effect.h Modified the effect library API to expose a library info structure containing an interface functions table. Also removed enums for audio channels, audio format and devices from effect API and use values from system/audio.h instead. Modified effects factory to support new library interface format and load libraries and efffects listed in audio_effects.conf file. The file audio_effects.conf is first loaded from /vendor/etc and then from /system/etc/audio_effects.conf if not found. Modified existing effect libraries to implement the new library interface.

* First submission of audio effect library from NXP software.Eric Laurent2010-07-171-0/+56
This CL contains the first open sourceable version of the audio effect library from NXP software. The effects implemented are: - Bass boost - Virtualizer (stereo widening) - Equalizer - Spectrum analyzer Source file for the effect engines are located under libeffects/lvm/lib The wrapper implementing the interface with the audio effect framework in under libeffects/lvm/wrapper The code of other effect libraries has also been reorganized fo clarity: - the effect factory is now under libeffects/factory - the test equalizer and reverb effects are under libeffect/testlibs - the visualizer is under libeffects/virtualizer Change-Id: I8d91e2181f81b89f8fc0c1e1e6bf552c5809b2eb
