There\n\tis one EffectModule per instance of an effect in a given audio session\n  EffectChain: group of effects associated to one audio session. There is one EffectChain per audio session.\n\tEffectChain for session 0 is for output mix effects, other chains are attached to audio tracks\n\twith same session ID. Each chain contains a variable number of EffectModules\n  EffectHandle: implements the IEffect interface. There is one EffectHandle object for each application\n\tcontrolling (or using) an effect module. THe EffectModule maintians a list of EffectHandles.\n\nAdded support for effect modules and effect chains creation in PlaybackThread.\nmodified mixer thread loop to allow track volume control by effect modules and call effect processing.\n\n-AudioMixer\nEach track now specifies its output buffer used by mixer for accumulation\nModified mixer process functions to process tracks by groups of tracks with same buffer\nModified track process functions to support accumulation to auxiliary channel\n\nChange-Id: I26d5f7c9e070a89bdd383e1a659f8b7ca150379c\n"

      "message": "Fix issue 2553359: Pandora does not work well with Passion deskdock / Cardock.\n\nThe problem is due to a too big difference between the buffer size used at the hardware interface and at the A2DP interface.\nWhen no resampling occurs we don\u0027t notice problems but the timing is very tight. As soon as resampling is activated, the AudioTrack underruns.\nThis is because the AudioTrack buffers are not resized when moving the AudioTrack from hardware to A2DP output.\nThe AudioTrack buffers are calculated based on a hardware output buffer size of 3072 bytes. Which is much less than the A2DP output buffer size (10240).\n\nThe solution consists in creating new tracks with new buffers in AudioFlinger when the A2DP output is opened\ninstead of just transfering active tracks from hardware output mixer thread to the new A2DP output mixer thread.\nTo avoid synchronization issues between mixer threads and client processes, this is done by invalidating tracks\nby setting a flag in their control block and having AudioTrack release the handle on this track (IAudioTrack)\nand create a new IAudioTrack when this flag is detected next time obtainBuffer() or start() is executed.\n\nAudioFlinger modifications:\n- invalidate the tracks when setStreamOutput() is called\n- make sure that notifications of output opening/closing and change of stream type to output mapping are sent synchronously to client process.\nThis is necessary so that AudioSystem has the new stream to output mapping when the AudioTrack detects the invalidate flag in the client process.\nPreviously their were sent when the corresponding thread loop was executed.\n\nAudioTrack modifications:\n- move frame count calculation and verification from set() to createTrack() so that is is updated every time a new IAudioTrack is created.\n- detect track invalidate flag in obtainBuffer() and start() and create a new IAudioTrack.\n\nAudioTrackShared modifications\n- group all flags (out, flowControlFlag, forceReady...) into a single bit filed to save space.\n\nChange-Id: I9ac26b6192230627d35084e1449640caaf7d56ee\n"
