Ever wonder what’s going on inside your audio equipment? How does the audio data on a CD, MP3, or WAV file stop being data and become sound? That “magic” is in large part thanks to a digital-to-analog converter or DAC.
A DAC takes digital data and transforms it into an analog audio signal. Afterward, it sends that analog signal to an amplifier. When you hear digital recordings, you’re actually listening to an analog signal that was converted from digital by a DAC. Even if you can’t see the DAC – although you sometimes can – it’s there.
