I was/am planning to simply use the speaker and mic for sound doppler spectral analysis of solid non-dense objects. Being an Engineer, I would imagine that real time capturing of the reflected sonic waves might be an issue when compared to the initial sent "ping" signals. Hence, in a nut-shell, my problem -- real-time!. I still need to work out the frequencies and corresponding amplitudes for different object densities. I am obviously in the "feasibility" stage of development.
Someone suggested to me that Android devices (and most real-time cell/pda devices) might contain an embedded MIB Module (Management Information Base) *http://en.wikipedia.org/wiki/Management_information_base*. If this is the case, then it could be a simpler matter of extracting the information from the MIB-module and doing the spectral analysis at that point. ie, it would look real-time. I am looking for what might be proprietary information (schematics, etc) of the guts of the Android or even iPhone, etc to see exactly how the transmitted and received signals are handled and digested, even for simple voice calls. This whole issue might be a lot simpler than I think, but it usually never is. Thanks for any and all comments and suggestions .
