2012-06-07Take latency and current time into account for visualizationMarco Nelissen
Buffer more data, and return the data that is currently being output from the audio output, to ensure that visualizations are smooth and responsive even when the audio output has a large latency and/or large buffers. b/6522728 Change-Id: I401637f01be7600b3c594a55c869036c13b206c0
2012-04-18Add support for scaling mode parameterJean-Michel Trivi
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).

2012-03-26fix visualizer inactivity detectionEric Laurent
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

2011-12-19audio effects: rename configure commandEric Laurent
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.

2011-11-10visualizer: reset buffer if playback is idleEric Laurent
Visualizer capture buffer must be reset if audio framework has stopped calling process for a given period of time to get read of residual data from previous captures. Issue 5571920. Change-Id: I6e73f971bb812cdbb2979a3b5e763abab07634eb

2011-07-11Audio Effect API: process reverse stream functionEric Laurent
Added function to audio effect interface for processing of a reverse stream. This is necessary for audio pre processes like echo cancellation. Change-Id: I6e12d79dbbed6376acdfc79304b8c0ab3f705eae
2011-07-07Moved and renamed effect API header filesEric Laurent
Moved specific effect header files to system/media/audio_effects/include/audio_effects and renamed to lower case (effect_xxx.h). Change-Id: Icfc2264bfd013cab0395d7e310ada636b9fe3621
2011-05-27New effect library APIEric Laurent
Moved and renamed media/EffectApi.h to hardware/audio_effect.h Modified the effect library API to expose a library info structure containing an interface functions table. Also removed enums for audio channels, audio format and devices from effect API and use values from system/audio.h instead. 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.

2010-09-24Fix error in AudioEffect command status reporting.Eric Laurent
AudioEffect::command() should not interpret the status returned in pReplyData unless the command is ENABLE or DISABLE. Also fixed: - bug in Visualizer::getWAveForm() status reporting. - wrong initialization value for capture buffer in visualizer engine. Change-Id: I60fb0011f9dba96ee74661dec1e8ef441edcaf35

2010-09-21Fix issue 2913071.Eric Laurent
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

2010-07-19Fixed problems in audio effect volume control.Eric Laurent
Fixed the following problems in audio effect volume control in AudioFlinger: - Make sure that the volumes returned by EffectChain::setVolume_l() are correct even is no change is detected since last call - Do not use isEnabled() to validate volume control but mState >= ACTIVE instead as the volume control must be also active in STOPPING and STOPPED states.

2010-07-17First submission of audio effect library from NXP software.Eric Laurent
This CL contains the first open sourceable version of the audio effect library from NXP software. The effects implemented are: - Bass boost - Virtualizer (stereo widening) - Equalizer - Spectrum analyzer Source file for the effect engines are located under libeffects/lvm/lib The wrapper implementing the interface with the audio effect framework in under libeffects/lvm/wrapper The code of other effect libraries has also been reorganized fo clarity: - the effect factory is now under libeffects/factory - the test equalizer and reverb effects are under libeffect/testlibs - the visualizer is under libeffects/virtualizer Change-Id: I8d91e2181f81b89f8fc0c1e1e6bf552c5809b2eb
