What type of input does a digital audio converter process?

A digital audio converter (DAC) is designed to convert digital audio signals into analog audio signals. This transformation is essential because most audio playback devices and speakers operate using analog signals. The primary function of a DAC is to process the digital signals that represent audio information and convert them into an analog form that can be output as sound.

While it is true that a DAC primarily converts digital audio signals, it is important to note that some specialized DACs can also be configured to handle both analog and digital inputs for various applications. However, in the context of the most common usage, standard digital audio converters specifically process digital signals.

The inclusion of both analog and digital in the provided correct answer reflects broader scenarios where a device might be expected to interact with both types of signals, although it is more typical for a DAC to focus on processing digital signals into analog format. This makes the answer relevant in specific contexts or applications of DAC technology.
