* fix visualizer inactivity detectionEric Laurent2012-03-261-9/+24
| | | | | | | | | | | | Current method implemented by the visualizer to detect that audioflinger has stopped providing audio buffers does not work if the application reads pcm captures too fast. The fix consist in implementing a method based on real time measurement only. One drawback is that the new method makes use of system calls that add some overhead to the process and capture functions. Change-Id: I53bd596b856f1cc7f0f47e08413af3335227100b

* Effect for multichannel PCM downmix to stereoJean-Michel Trivi2012-03-073-0/+1013
| | | | | | | | | | | First pass at implementing an audio effect whose role is to downmix multichannel PCM buffers to stereo. The effect is not handling volume changes. The effect code here handles quad, 4.0, 5.1 and 7.1 input configurations, to optimize the most commom configurations, and does not yet handle generic multichanel configurations.

* audio preprocessing: fix multiple enable problemEric Laurent2012-02-171-1/+14
| | | | | | | | | | | Do not set the effect state back to configured when a configuration command is received while the effect is enabled. Instead just check that the new config is the same as current config. It is normal to receive a config command from the framework while enabled if a new effect is added on the same session.

| | | | | | | | | | | Several source files privately defined macros LIKELY and UNLIKELY in terms of __builtin_expect. But <cutils/compiler.h> already has CC_LIKELY and CC_UNLIKELY which are intended for this purpose. So rename the private uses to use the standard names. In addition, AudioFlinger was relying on the macro expanding to extra ( ). Change-Id: I2494e087a0c0cac0ac998335f5e9c8ad02955873

| | | | | | | | | | | | | Renamed audio effect library interface command for audio format configuration from EFFECT_CMD_CONFIGURE to EFFECT_CMD_SET_CONFIG. 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 EFFECT_CMD_CONFIGURE_REVERSE to EFFECT_CMD_SET_CONFIG_REVERSE. Implemented EFFECT_CMD_GET_CONFIG in exisitng effect libraries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The virtualizer and bass boost effects should be disabled when not playing throught headsets or headphones. There is a bug in current wrapper implementation that makes that those effects are not disabled if the effect is enabled by the user after the headset has been removed (current logic only works if the device selection occurs while the effect is enabled).

* Audio framework: support for audio pre processingEric Laurent2011-07-184-7/+73
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.
