* Audio framework: support for audio pre processingEric Laurent2011-07-184-7/+73
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Audio preprocessing wrapper for webrtc.Eric Laurent2011-07-172-0/+1641
| | | | | | | | This wrapper implements the interworking layer between the audio effect interface defined by the effect framework for audio preprocessing and the native interface of webrtc audio processing module. Change-Id: I3f9319730c102599cdf0dda520a53d90b4165114

* New effect library APIEric Laurent2011-05-2711-379/+812
| | | | | | | | | | | | | | | | | 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.

* Fix issue 3499926.Eric Laurent2011-03-011-8/+14
| | | | | | | | | Make sure that NumberEffectsEnabled is decremented at the same time as SamplesToExitCountBb reaches 0 in Effect_process(). Not doing so causes NumberEffectsEnabled not being decremented if Effect_setEnabled() is called after SamplesToExitCountBb reaches 0 and before next Effect_process() is called.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Use a constant input level to the reverb engine and implement volume control in the insert reverb. This avoids the volume spikes when an effect that was inserted after the reverb is disabled or removed. - Fix clicks (one silent buffer) at the end of the reverb disable period. - Modified volume management in audioflinger so that the volume ramp is also done by the insert effect if present when the track is paused (avoids clicks). - Increased room level for all presets. Also fixed problems with output stage session (-1): - effect bundle wrapper was not designed to support session -1 - the permission check in audioflinger for using session -1 failed due to a wrong usage of getCallingPid() Change-Id: Id1ff51327263364bf71d3f2668fa5cde4311d84f
