I would like to know if it's possible to modify Android OS (official image from AOSP) to add preprocessing to normal phone call playback sound - and how.
I already know it's possible to do so for app audio playback (by modifying HAL), but I'm not sure if that will also work for phone calls. I need to know whether it's possible before getting into a longer project - right now I don't have a quick way to test it. I'm OK with targeting only a specific device (Nexus 5X), and modifying Qualcomm code. Also, I only need to filter playback - I don't care about recording (uplink). -- -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting --- You received this message because you are subscribed to the Google Groups "android-porting" group.
