| * audio framework: manage stream volume per deviceEric Laurent2012-01-171-4/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Improve volume management by keeping track of volume for each type of device independently. Volume for each stream (MUSIC, RINGTONE, VOICE_CALL...) is now maintained per device. The main changes are: - AudioService now keeps tracks of stream volumes per device: volume indexes are kept in a HashMap < device , index>. active device is queried from policy manager when a volume change request is received initalization, mute and unmute happen on all device simultaneously - Settings: suffixes is added to volume keys to store each device volume independently. - AudioSystem/AudioPolicyService/AudioPolicyInterface: added a device argument to setStreamVolumeIndex() and getStreamVolumeIndex() to address each device independently. - AudioPolicyManagerBase: keep track of stream volumes for each device and apply volume according to current device selection.

| * Use audio_mode_t consistentlyGlenn Kasten2012-01-121-2/+2
| | | | | | | | | | | | | | It was int or uint32_t. Also make getMode() const. Change-Id: Ibe45aadbf413b9158e4dd17f2b3bcc6355288d37
* | Use audio_stream_type_t consistentlyGlenn Kasten2012-01-131-6/+6
|/ | | | | | | | | At native level it was a mixture of audio_stream_type_t, int, uint32_t, and uint8_t. Java is still int. Also fixed a couple of hard-coded -1 instead of AUDIO_STREAM_DEFAULT, and in startToneCommand a hard-coded 0 instead of AUDIO_STREAM_VOICE_CALL. Change-Id: Ia33bfd70edca8c2daec9052984b369cd8eee2a83
* Audio effects: track CPU and memory use separatelyEric Laurent2011-08-111-1/+20
| | | | | | | | | | | | | | | | | | | | | | Before this change, CPU and memory usage for an audio effect were registered and checked against the limit by audio policy manager upon effect instantiation. Even if an effect was not enabled it would prevent another effect to be created if the CPU load budget was exceeded, which was too restrictive. This change adds a method to register/unregister CPU load only when an effect is enabled or disabled. It also adds a mechanism to place all effects on the global output mix in suspend state (disabled) when an effect is enabled on a specific session. This will allow applications using session effects to have the priority over others using global effects. Also fixes some issues with suspend/restore mechanism: - avoid taking actions when an effect is disconnected and was not enabled. - do not remove a session from the suspended sessions list when corresponding effect chain is destroyed.

* Added APIs for audio preprocessingEric Laurent2011-07-251-0/+49
| | | | | | | | | | | | | | | Added APIs to control pre processes applied on captured audio. Those APIs are still hidden until reviewed by API council. Three types of standard pre processes are supported: - Automatic Gain Control (AGC) by AutomaticGainControl class - Acoustic Echo Cancellation (AEC) by AcousticEchoCanceler class - Noise Suppression (NS) by NoiseSuppressor class A method is added to AudioEffect class to query audio pre processings applied by default by the platform on a given AudioRecord session ID.

* Audio framework: support for audio pre processingEric Laurent2011-07-181-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix issue 3371080Eric Laurent2011-02-031-1/+19
| | | | | | | | | | | | | | | | | | | | | | Modified default volume control logic in AudioService: 1 IN_CALL volume if in video/audio chat 2 NOTIFICATION if notification is playing or was playing less than 5s ago. 3 MUSIC Modified silent mode: - now also affect MUSIC stream type - entering silent mode when VOL- hard key is pressed once while selected stream volume is already at 0 (except for VOICE_CALL stream). - exiting silent mode when pressing VOL+ hard key while in silent mode Play sound FX (audible selections, keyboard clicks) at a fixed volume. Modified audio framework: - isStreamActive() method now implemented in AudioPolicyManagerBase (previously AudioFlinger) - iStreamActive() now specifies a time window during which the stream is considered active after it actually stopped.

* Audio policy manager changes for audio effectsEric Laurent2010-07-201-17/+131
| | | | | | | | | | | | | | | 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. Change-Id: Ida43484b06e9b890d6b9e53c13958d042720ebdb

| | | | | | | use pointers as handles to inputs and outputs. Use integers instead of void* as input/output handles at IAudioFlinger and IAudioPolicyService interfaces. AudioFlinger maintains an always increasing count of opened inputs or outputs as unique ID.
* Fix issue 1795088 Improve audio routing codeEric Laurent2009-07-231-0/+423
Initial commit for review. Integrated comments after patch set 1 review. Fixed lockup in AudioFlinger::ThreadBase::exit() Fixed lockup when playing tone with AudioPlocyService startTone()
