a189a6883ee55cf62da1d7bf5bf5a8ab501938a4 20-Feb-2012 Glenn Kasten <gkasten@google.com> Use struct assignment instead of explicit memcpy

for POD structs effect_descriptor_t and effect_config_t

Renamed audio effect library interface command for audio format
This makes the naming more consistent with other exixsting commands
and allow adding a new command to get the configuration (EFFECT_CMD_GET_CONFIG).
Same change for reverse channel configuration renamed from

Implemented EFFECT_CMD_GET_CONFIG in exisitng effect libraries.

ba7b8f881a9b6b21803752326d2932a3bd42d7cf 18-Jun-2011 Eric Laurent <elaurent@google.com> Audio Effect API: process reverse stream function

Added function to audio effect interface for processing of
a reverse stream.
This is necessary for audio pre processes like echo cancellation.

6d8b694d999e9be7d5dcc336535832a80fb6f61f 24-Jun-2011 Eric Laurent <elaurent@google.com> Moved and renamed effect API header files

Moved specific effect header files to
and renamed to lower case (effect_xxx.h).

e1315cf0b63b4c14a77046519e6b01f6f60d74b0 18-May-2011 Eric Laurent <elaurent@google.com> New effect library API

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.

3be9523784cc4038f601e510faee595117cdacb3 30-Jul-2010 Eric Laurent <elaurent@google.com> Audio effects: aligned Equalizer API argument types on OpenSL ES SLEqualizerItf.

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.

2c8e5cab3faa6d360e222b7a6c40a80083d021ac 09-Jul-2010 Eric Laurent <elaurent@google.com> First submission of audio effect library from NXP software.

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
