A computer needs a soundcard (aka Audio Interface) to receive or send audio signals. Often, the computer acts as a Digital Recorder. Usually, the soundcard will convert the signal from ANALOG to DIGITAL for the computer. Then, it converts the DIGITAL signal from the computer back to ANALOG to be played back for humans
A computer soundcard can be internal or external. Many external soundcards use Firewire or USB. All computer soundcards have ADC’s and DAC’s built into them. Some soundcards even have built-in preamps.
