First submission of audio effect library from NXP software.
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
