# Shifting an audio signal from 0 - 4V to -2 - 2V

I'd like to transmit an audio signal over a digital radio and I figured out I'd need an op-amp in an inverting configuration on the transmitting side to turn a -2V to 2V signal into a 0-4V one. That will be fed into an ADC which then supplies the radio with a digital signal. On the receiving side though I'd need to do the reverse in order to hear the audio properly, so that means the 0-4V signal now needs to be the -2V to 2V one again. Could an op-amp also be used for this, and how? Thanks for helping!
