| | | | | | | | | | | | | | | | The effects libraries were exporting many more symbols than needed. This reduces the exported symbols to just the needed ones (basically just "AELI"), which happens to also save about 28KB. Change-Id: I115077e52e8dc845282e6f62a522908d26dd72d6

* | Fix THD with max user EQ preset volume againEric Laurent2012-09-172-93/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | There was a problem with previous fix in 1b6c677c where the THD was good for max volume but bad for intermediate high volume values. This fix does not limit the band gains but apply a correction to the effect bundle volume to take into account not only the maximum band gain but also the average band gains weighted by the proximity of each band to the max gain band.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | The ThreadBase class now has a separate member for input and output devices (mInDevice, mOutDevice). Only query get_supported_devices() from audio HAL if the function is exposed and if the audio policy manager did not specify the audio module to open. Also fixed bug in AEC preprocessing that would reset to default output device when an input device was given. Change-Id: I19d4d06aeb920b068e3ef31e6e6be6345ce5d67a

* Prevent occurences of clipping in loud downmixed scenesJean-Michel Trivi2012-05-241-20/+20
| | | | | | | | | | | | The downmixer effect is a mixer, wich, like the platform mixer, hard-clips. To prevent clipping during loud scenes across multiple chanels, apply a fixed attenuation on the result of the downmix. Note that this attenuation is lower the theoretical required attenuation (except for quad and surround) but is adequate for most content.

* Stereo downmixer supports generic configurations. Fix 7.1 downmixJean-Michel Trivi2012-05-162-11/+282
| | | | | | | | | | | | | | | | | | Added a generic downmixer to stereo function to handle the multichannel configurations not supported by the dedicated downmix functions. It first verifies the mask is supported, and then derives channel indices for the downmix. Added support for forcing the generic downmixer to be always used instead of the format-specific functions (define DOWNMIX_ALWAYS_USE_GENERIC_DOWNMIXER to force it). Fixed 7.1 downmix function where handling of accumulate vs overwrite was inversed. Bug 4280902 Change-Id: I8259b32c4e90f76ef4dcd803592fc71df4ae90c5
* Downmix support for 5.1 and quad with side channelsJean-Michel Trivi2012-04-231-5/+28
| | | | | | | | | In DOWNMIX_TYPE_FOLD mode, add support for variants of quad and 5.1 channel masks where the "side" channels are used instead of the "back" channels. These variants have the same channel order, so they can share the same downmix function. Change-Id: I5f9cb7cb120927189de680c2a968d6136dc1fc43

* | Add support for scaling mode parameterJean-Michel Trivi2012-04-181-32/+59
|/ | | | | | | | | | | | | | | | | | | | | | Support VISUALIZER_PARAM__SCALING_MODE parameter. Modify process() function to use new volume scaling parameter, used to set whether captured values are maximized by current headroom in the buffer (default existing behaviora) or left as is and thus affected by volume. Modify AudioEffect to allow subclasses to override the following events: control status changed, enable status changed, command executed. In Visualizer class (a subclass of AudioEffect), reset the scaling mode and capture size on the actual effect as cached when control is regained. This will allow the effect to be properly configured whenever Visualizers with different scaling modes or capture sizes are released (e.g. from java release() method).

* AudioMixer uses downmix effect for multichannel contentJean-Michel Trivi2012-04-092-1/+8
| | | | | | | | | | | | | | In the AudioMixer structure associated with each track, add an object that acts as the buffer provider when the track has more than two channels of input in the mixer. This object, DownmixerBufferProvider, gets audio from the actual buffer provider of the track, and applies a downmix effect on it. The downmix effect is created and configured when the track gets created in AudioFlinger, which causes AudioMixer::getTrackName() to be called with the new track's channel mask. It is released when the track is disabled in the mixer. Change-Id: I05281ed5f61bef663a8af7ca7d5ceac3517c82db
* 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.

| | | | | | | | | | | | | 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.
