Add new audio mode and recording source for audio communications
other than telelphony.
The audio mode MODE_IN_CALL signals the system the device a phone
call is currently underway. There was no way for audio video
chat or VoIP applications to signal a call is underway, but not
using the telephony resources. This change introduces a new mode
to address this. Changes in other parts of the system (java
and native) are required to take this new mode into account.
The generic AudioPolicyManager is updated to not use its phone
state variable directly, but to use two new convenience methods,
isInCall() and isStateInCall(int) instead.
Add a recording source used to designate a recording stream for
voice communications such as VoIP.
Update the platform-independent audio policy manager to pass the
nature of the audio recording source to the audio policy client
interface through the AudioPolicyClientInterface::setParameters()
method.
SIP calls should set the audio mode to MODE_IN_COMMUNICATION,
Audio mode MODE_IN_CALL is reserved for telephony.
SIP: Enable built-in echo canceler if available.
1. Always initialize AudioRecord with VOICE_COMMUNICATION.
2. If echo canceler is available, disable our echo suppressor.
Note that this CL is intentionally not correcting the
getAudioSourceMax() return value in MediaRecorder.java as the
new source is hidden here.

o Prepare for publishing MediaMetadataRetriever as public API
step one:
o replaced captureFrame with getFrameAtTime
o removed getMode
o Replace MediaMetadataRetriever.captureFrame() with MediaMetadataRetriever.getFrameAtTime()
as part of the preparation for publishing MediaMetadataRetriever as public Java API
o Remove captureFrame from MediaMetadataRetriever.java class
It has been replaced by getFrameAtTime() method
o Replace extractAlbumArt() with getEmbeddedPicture() in MediaMetadataRetriever.java
o Publish MediaMetadataRetriever.java as public API
o Removed setMode() methods and related mode constants
o Removed some of the unused the metadata keys
o Updated the javadoc
o part of a multi-project change.

The java doc for visualizer FFT capture was not describing
correctly the layout of the data returned by getFft() method.
Change-Id: Idec09538490ea73b211db253b1b8b733ca4d4a72
- Created sub-package android.media.audiofx for audio effects.
- Hid AudioEffect class contructor, methods and variables not needed by
applications
- Added more javadoc comments for AudioEffect Class
Change-Id: Ibbb40d4e714bb248aa32cf82d7763d74efae96d1
Scale audio signal during capture according to peak level so that
returned values on 8 bits contain enough information even for weak
signals.
Also do not reject requests to enable/disable the visualizer if we are
already in the requested state.
Change-Id: I07a705619764350834e61f82d161761eab688747
Added intents to launch audio effects control panel UI and
communicate playback state from media player applications
to effect control application/service.
Change-Id: Iede23ae11fa9f0802df5f36299dd80ea57eda376
Changed the type of reverb preset constants exposed by the PresetReverb API to
match the type of the setPreset() method parameter.

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.

app is the phone is ringing, even in silent mode.
Use the PhoneStateListener to know whether the phone is ringing,
as the mode is not MODE_RINGTONE when ringing in silent mode.

- Fixed constant inversions in AudioEffect.java
- Do not return error when enabling an already enabled effect
- Update cached effect state in native AudioEffect class when effect is enabled/disabled by command() method
- Remove click when restarting effect during disable sequence
- Fixed problem in master mute management when volume control is delegated to effect.
Change-Id: I6df4ce9fcc54fdc7345df858f639d20d802d6712
This change unhides all public APIs for controling audio effects exposed
by the following classes:
- AudioEffect
- BassBoost
- EnvironmentalReverb
- Equalizer
- PresetReverb
- Virtualizer
- Visualizer
Also fixes several problems in javadoc.
Change-Id: I541ee4ad0232312ec720545737cbcdb8c9a82597
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.

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.
Change-Id: Ic25ddb135e2cec5a68c181d727321f5ac7a1ab6b
Added methods to AudioTrack and MediaPlayer java classes to enable use of
auxiliary audio effects. The effect can be attached and detached by specifying its
ID and the send level controlled.
Change-Id: Ie74ff54a453096a742688476f612ce355543b6f3
Defined the following JAVA classes on top of AudioEffect class to facilitate control
off built-in audio effects with APIs aligned with interfaces defined in OpenSL ES
specification:
- BastBoot.java
- Equalizer.java
- PresetReverb.java
- EnvironmentalReverb.java
- Virtualizer.java
Split reverb API header file in two, one for preset reverb and one for environmental reverb.
Some changes in test reverb to support preset reverb.

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

Problem:
When the bluetooth device is removed, the AudioService clears all active SCO connections
and unlinks from the client application's binder interface death.
The problem is that the unlinking is done even if no more connections are active for a given client,
which throws a runtime exception that is not catched causing the system server to crash.
The fix consists in calling unlinkToDeath() in ScoClient.clearCount() only if the number of
active SCO connections for this client is not 0. The NoSuchElementException exception is also
catched when calling unlinkToDeath()

Audio sessions are used to associate audio effects to particular instances (or groups) of MediaPlayers or AudioTracks.
Change-Id: Ib94eec43241cfcb416590f435ddce7ab39a07640
Use setParameters() API to indicate to audio HAL that we are restarting the media server after a crash.
The use made by audio HAL implementation of this indication is platform specific.
Change-Id: I085b174fa1474575da0e4d295921079b6b68efb8
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.
