As such, analog recordings deliver the most accurate audio reproduction of a sound. When plotted on a graph, analog signals look like smooth, continuous sine waves, identical to the wave generated by the original sound. To understand this, it’s important to first grasp the difference between analog and digital signals.Īn analog signal is a continuous wave that constantly varies in amplitude or voltage. Why do we convert analog to digital signals only to change them back? However, they can also be used as an external stand-alone tool that you can hook up to your audio devices. That signal then gets sent to an amplifier, before getting sent to your headphones or speakers.ĭACs are typically integrated into many devices such as smartphones, tablets, and computers. So, when does the actual conversion from digital to analog take place? Well, it occurs in a split second before playback.īefore the music reaches your ears, the DAC processes all the binary codes that make up a digital audio signal and converts them into an analog signal. What Is a DAC? Digital to analog conversion process.Ī DAC (digital-to-analog converter) is a tech tool that converts digital audio signals (binary codes) into analog waveforms (what you can hear).
