* Fix issue 3157123.Eric Laurent2010-11-191-1/+2
| | | | | | | Use a Mutex wherever atomic operations were used in AudioTrack, AudioRecord, AudioFlinger and AudioEffect classes. Change-Id: I6f55b2cabdcd93d64ef19446735b8f33720f8dbc
* Audio effects: modified command() parameter types.Eric Laurent2010-07-281-7/+11
| | | | | | | The type of the cmd, cmdSize and *pReplySize parameters of the effect control interface command() function have been modified from int to uint32_t. This is more consistent with their role. Change-Id: I84d289fc262d6753747910f06f485597dfee6591
* Added Visualizer effect.Eric Laurent2010-07-071-33/+37
| | | | | | | | | | | | | | The visualizer enables application to retrieve part of the currently playing audio for visualization purpose. It is not an audio recording interface and only returns partial and low quality audio content as a waveform or a frequency representation (FFT). Removed temporary hack made in MediaPlayer for animated wall papers based on audio visualization (snoop() method. This commit also includes a change in AudioEffect class: - the enable()/disable() methods have been replaced bya more standard setEnabled() method. - some fixes in javadoc Change-Id: Id092a1340e9e38dae68646ade7be054e3a36980e
* Various fixes and improvements in audio effects implementationEric Laurent2010-06-251-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Effect API: - Use different definitions for audio device, channels, formats... in AudioSystem and EffectApi: Removed media/AudioCommon.h file created for initial version of EffectApi - Indicate audio session and output ID to effect library when calling EffectCreate(). Session ID can be useful to optimize the implementation of effect chains in the same audio session. Output ID can be used for effects implemented in audio hardware. - Renamed EffectQueryNext() function to EffectQueryEffect() and changed operating mode: now an index is passed for the queried effect instead of implicitly querying the next one. - Added CPU load and memory usage indication in effects descriptor - Added flags and commands to indicate changes in audio mode (ring tone, in call...) to effect engine - Added flag to indicate hardware accelerated effect implementation. - Renamed EffectFactoryApi.h to EffectsFactoryApi.h for consistency with EffectsFactory.c/h Effect libraries: - Reflected changes in Effect API - Several fixes in reverb implementation - Added build option TEST_EFFECT_LIBRARIES in makefile to prepare integration of actual effect library. - Replaced pointer by integer identifier for library handle returned by effects factory Audio effect framework: - Added support for audio session -1 in preparation of output stage effects configuration. - Reflected changes in Effect API - Removed volume ramp up/down when effect is inserted/removed: this has to be taken care of by effect engines. - Added some overflow verification on indexes used for deferred parameter updates via shared memory - Added hardcoded CPU and memory limit check when creating a new effect instance Change-Id: I43fee5182ee201384ea3479af6d0acb95092901d
* Issue 2667802: [Audio Effect Framework] AudioEffect base class and JNI.Eric Laurent2010-06-111-0/+462
Added AudioEffect C++ class. AudioEffect is the base class for effect specific implementations, OpenSL ES effect interfaces and audio effect JNI. Added the AudioEffect JNI and AudioEffect JAVA class. AudioEffect is the base class to implement more specific JAVA classes to control audio effects from JAVA applications. Change-Id: If300a1b708f2e6605891261e67bfb4f8330a4624
