- Fixed click when re-enabling effect during the turn off phase:
make sure the effect states where effect is processed are the same
where volume control is delegated to effect.
- Fixed click when effect is deleted while still active: do not apply
volume ramp if an effect having volume control was just removed from the
effect chain.
Also fixed a crash when PCM dump is enabled in effect bundle wrapper.

- Virtualizer now uses the correct control parameter, instead of reverberation
- Volume smoothing for first frame has been added
- Equalizer_setParameter now returns correct error code
- Correcting Non-Linear compressor gain step noise during transitions and effect level changes
- Removed SVN header blocks
- Memory and MIPS values have been added to the API
- Reverb uses a more efficient malloc for input PCM
- Reverb DecayHFRatio now ranges up to 2000
- Logging has been removed for most volume functions

Modified lvm reverb wrapper code to expose a preset reverb interface.
Also removed debug log from bundle and reverb wrapper.

- SessionId is now stored as a SessionNo
- Effects now stop being called after a delay
- Unix EOL fixed for .java and .xml
- Updated lines limited to 100 characters.
- Removed the remaining warnings from the wrapper code
- Added reverb

The "strength supported" parameter for bass boost and virtualizer effect was incorrectly using a
short value whereas it should be an int. This is to comply to the definition of boolean type in OpenSL ES
that is uint32.
Change-Id: I74ccb61dcc70fc9d390524a1ca5bbbd8b13ab1af
Modified types of some arguments and returned values of the Equalizer class from int to short
to match those defined by OpenSL ES SLEqualizerItf interface.
Also fixed a problem with set properties in equalizer engine implementation.

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.

a single call.
Addional changes:
- Fixed simulator build
- Use effect interface UUIDs from OpenSL ES includes when available
- Added cleanspec rules to remove now obsolete test effect libraries
- Fixed bug in AudioEffect JNI setParameter function.

Remaining warnings in the code have been removed
Core components support seamless insertion in the audio stream at playtime (Enabling / Disabling the effect).
Change-Id: Icae7085305fad663faeb5a94cb673b41cec5a9f1
The status in the command reply field was not initialized by Effect_command() for
EFFECT_CMD_INIT causing unpredictable failures when initializing an effect.
Change-Id: I7dccb094c9244fad4ed9aea3062a395db295e082
Added methods for audio effects management by audio policy manager.
- control of total CPU load and memory used by effect engines
- selection of output stream for global effects
- added audio session id in parameter list for startOutput() and stopOutput().
this is not used in default audio policy manager implementation.
Modifications of audio effect framework in AudioFlinger to allow moving and reconfiguring
effect engines from one output mixer thread to another when audio tracks in the same session
are moved or when requested by audio policy manager.
Also fixed mutex deadlock problem with effect chains locks.

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
