There are several DAC architectures the suitability of a DAC for a particular application is determined by figures of merit including: resolution, maximum sampling frequency and others. An analog-to-digital converter (ADC) performs the reverse function. In electronics, a digital-to-analog converter (DAC, D/A, D2A, or D-to-A) is a system that converts a digital signal into an analog signal. That data is then stored onto the disc in order to be decoded later by a CD player. (On a CD, the sampling rate is 44,000 samples per second so, there are 44,000 numbers stored per second of music). The analog wave is sampled at the desired interval and then turned into numbers that are stored on the digital device. Now, most of the time recordings are saved as digital data. That wave could then be read, amplified and sent to a speaker to produce the sound it created. The waveform of the microphone is an analog wave, therefore making the wave on the tape analog as well. Back in the day, music was recorded using the signal straight from the microphone and tracked directly to tape.

This guide is to help you step-by-step in learning about DACs, what they do, and how to find the right one for your audio system and needs.
There are many different kinds of DACs out there, and an infinite number of questions that can be asked about them. What is a DAC? What does it do? Why do you need one? How does it work? The DAC is a necessary ingredient to the audiophile recipe.
