measure audio line level

I have a requirement to be able to be able to measure the audio level of an audio line. I am wondering if anyone has done anything like this using an adc of of PIC?

I am thinking about setting up an integrator circuit with some time constant to capture how much audio signal was present over a period. The ADC value would roughly correspond to the volume?

Any thoughts on how well an ADC would interpret this as the level of volume?
