* 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.

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

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