Is anywhere program which helps on microphone oscillation

I.m plan to use FV-1 to make an anti oscillation module to microphone.
I know that by shifting whole signal spectrum up 5Hz is is possibility to avoid oscillations when sound from speakers reach the microphone.

Has anyone the code like that?

Is it possible to write it on FV-1?

There is a frequency shifter code here which should do what you want:

I tried this before with pitch change program,it defeated the problem ,I didn't measured yet but ,that was really more than 5 hz and ,Both for negative and positive change could do.
