RF taps for noise immunity in Audio

Thread Starter

I am designing an audio (voice actually) front end (only for recording ) for a speech compression application.
So I need to design a pre amplifier for the mic (simple electret type)and apply the o/p to an ADC.
Now Do we need to put RF taps to avoid RF noise interference .?? How sould the technique be?? Can any one provide some application note on how to do and what are the values to be placed??.

Are there any RF immune preamplifiers availible.??
Please help
