What is a key factor that differentiates digital audio systems?

A key factor that differentiates digital audio systems is the bit depth and sample rate. In digital audio, bit depth determines the resolution of each audio sample and affects the dynamic range of the sound. A higher bit depth allows for more precise audio representation, reducing the risk of distortion and enabling a more nuanced sound capture.

The sample rate indicates how many samples of audio are taken per second, influencing the frequency response of the audio system. A higher sample rate can capture higher frequency sounds, thus providing a clearer and more detailed representation of audio.

Together, bit depth and sample rate are crucial specifications that define the quality and fidelity of the audio in digital systems, distinguishing them from other audio systems that might rely on different technologies or formats. Hence, understanding these factors is essential for anyone working with digital audio.
