Android appliquer un effet audio sur tout audio out - Stack Overflow

I am having one audio effect written in C, and i want to integrate my audio effect in android ICS BSP for custom board and effect needs to be applied globally if set once, regardless of audio playing application. Can anybody point me at which level i can integrate my effect? Driver level or post processing module of android (which module)?

I tried using 0 audio session id but it doesn't apply globally and also it is deprecated.

I need to have raw audio buffer in order to apply effect. Please guide me to correct direction.
