Sundog is right. A longer answer is that whether the application processor can access in-call audio is very device specific; on the G1 this is not supported (only the modem processor can).
For the record, there are two CPUs on the G1, an ARM9 handling GSM/radio/whatever, and the ARM11 Android runs on (there are also two DSPs, the mDSP for the modem, and aDSP for applications; isn't that fun :-)) On Wed, Mar 4, 2009 at 7:00 PM, Sundog <[email protected]> wrote: > > Short answer: no. > > On Mar 4, 6:30 am, Jozef Habdank <[email protected]> wrote: > > Hello Android Deveopers, > > > > I am going to write a master thesis about the mobile technologies, and > > part of it is writing an application that will be able to change/ > > modify sound going out and coming in to the phone (via the GSM).
