DAC = Digital to Analogue Converter, so it is an output/playback device. You need to use a card with an ADC (Analogue to Digital Converter) for input/record. There aren't as many ADC as DAC cards and a USB sound card might be an alternative option.

That card DOES have the ability to record from a microphone, the HiFiBerry DOES NOT allow you to do that. Don't buy the HiFiBerry, buy the cirrus one instead.
