A Digital Audio Converter (DAC) is a device that transforms digital audio signals into analog signals. This process is essential for playing digital music files, as most speakers and headphones require analog signals to produce sound. DACs are commonly found in various devices, including smartphones, computers, and audio interfaces. DACs can vary in quality, affecting the overall sound experience. Higher-quality DACs can provide clearer and more detailed audio, making them popular among audiophiles. Many music streaming services and high-resolution audio formats benefit from using advanced DACs to enhance sound fidelity and deliver a better listening experience.
