* Fix volume problems with insert revertEric Laurent2010-09-133-28/+121
| | | | | | | | | | | | | | | | | - Use a constant input level to the reverb engine and implement volume control in the insert reverb. This avoids the volume spikes when an effect that was inserted after the reverb is disabled or removed. - Fix clicks (one silent buffer) at the end of the reverb disable period. - Modified volume management in audioflinger so that the volume ramp is also done by the insert effect if present when the track is paused (avoids clicks). - Increased room level for all presets. Also fixed problems with output stage session (-1): - effect bundle wrapper was not designed to support session -1 - the permission check in audioflinger for using session -1 failed due to a wrong usage of getCallingPid() Change-Id: Id1ff51327263364bf71d3f2668fa5cde4311d84f
* LVM release 1.09 deliveryEric Laurent2010-09-094-135/+69
| | | | | | | | | | | - Reverb: - 1 channel mixed has gain zero - core componenet now only outputs STEREO samples - wrapper now handles only STEREO from the Reverb Core - Bass Boost: - increase scratch memory Change-Id: I00ae31051cc40a7006fc993420facfeb4d30dc52
* Modify type of some environmental reverb parametersEric Laurent2010-09-081-14/+16
| | | | | | | | | Changed type of decay time, reverb delay and reflections delay parameters from signed to unsigned int to match OpenSL ES interface definition. Also fixed some type casts in lvm reverb wrapper. Change-Id: I5ca5e76a87c2590f01f031f3168355586ef22556
* LVM release 1.08 delivery.Eric Laurent2010-09-035-41/+69

* Audio Effects: fix problems in volume control.Eric Laurent2010-08-311-8/+22
| | | | | | | | | | | | | - Fixed click when re-enabling effect during the turn off phase: make sure the effect states where effect is processed are the same where volume control is delegated to effect. - Fixed click when effect is deleted while still active: do not apply volume ramp if an effect having volume control was just removed from the effect chain. Also fixed a crash when PCM dump is enabled in effect bundle wrapper. Change-Id: Ib562f5cf75c69af75df0e862536262e2514493e4
* LVM release 1.07 delivery.Eric Laurent2010-08-27188-1599/+231
| | | | | | | | | | | | | | - Virtualizer now uses the correct control parameter, instead of reverberation - Volume smoothing for first frame has been added - Equalizer_setParameter now returns correct error code - Correcting Non-Linear compressor gain step noise during transitions and effect level changes - Removed SVN header blocks - Memory and MIPS values have been added to the API - Reverb uses a more efficient malloc for input PCM - Reverb DecayHFRatio now ranges up to 2000 - Logging has been removed for most volume functions Change-Id: Ib59e7e331263c3811559231b4ae90c82e34a8421
* Added preset reverb.Eric Laurent2010-08-242-54/+199
| | | | | | | Modified lvm reverb wrapper code to expose a preset reverb interface. Also removed debug log from bundle and reverb wrapper. Change-Id: If9b95d91e25a6ff834decdfdda34b17df9b46967
* LVM release 1.05 deliveryEric Laurent2010-08-2026-154/+5051
| | | | | | | | | | | | - Click have been removed from the HP filter activation in the BassBosst Effect. - SessionId is now stored as a SessionNo - Effects now stop being called after a delay - Unix EOL fixed for .java and .xml - Updated lines limited to 100 characters. - Removed the remaining warnings from the wrapper code - Added reverb Change-Id: I03a2b3b5ee2286958f4901acc8d9b0daf9e2d7c6
* Audio Effects: fixed "strength supported" parameter size.Eric Laurent2010-08-181-2/+15
| | | | | | | | The "strength supported" parameter for bass boost and virtualizer effect was incorrectly using a short value whereas it should be an int. This is to comply to the definition of boolean type in OpenSL ES that is uint32. Change-Id: I74ccb61dcc70fc9d390524a1ca5bbbd8b13ab1af
* Audio effects: aligned Equalizer API argument types on OpenSL ES SLEqualizerItf.Eric Laurent2010-07-301-15/+43
| | | | | | | | | Modified types of some arguments and returned values of the Equalizer class from int to short to match those defined by OpenSL ES SLEqualizerItf interface. Also fixed a problem with set properties in equalizer engine implementation. Change-Id: I75894bad0cb67b01c18ca5e22f9687e75ee491b8
* Audio effects: modified command() parameter types.Eric Laurent2010-07-281-3/+3
| | | | | | | The type of the cmd, cmdSize and *pReplySize parameters of the effect control interface command() function have been modified from int to uint32_t. This is more consistent with their role. Change-Id: I84d289fc262d6753747910f06f485597dfee6591
* Audio Effects: added methods to effects java classes to store and load ↵Eric Laurent2010-07-273-78/+65
| | | | | | | | | | | | | | current effect settings in a single call. Addional changes: - Fixed simulator build - Use effect interface UUIDs from OpenSL ES includes when available - Added cleanspec rules to remove now obsolete test effect libraries - Fixed bug in AudioEffect JNI setParameter function.

* Audio policy manager changes for audio effectsEric Laurent2010-07-201-1/+1
| | | | | | | | | | | | | | | 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
* First submission of audio effect library from NXP software.Eric Laurent2010-07-17177-0/+29741
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
