Is any AGC function implemented in the audio paths of the Nokia 30?
My problem is as follows:
The application for the Nokia 30 will include a primitive loudspeaking emergency telephone. The type and installation of loudspeaker is already fixed (and definitely not a good choice). A very small, low cost, vandal-proof unit is used; hence a very bad sound quality and low maximum sound level results. An AGC is definitely needed in the system due to the varying signal levels from PSTN.
