High-Definition Audio refers to sound quality that exceeds the standard audio formats, providing a more detailed and immersive listening experience. It typically includes higher sample rates and bit depths, allowing for a broader frequency range and greater dynamic range. This means that listeners can hear subtle nuances in music and sound that are often lost in lower-quality formats. Common formats for High-Definition Audio include FLAC, DSD, and WAV. These formats are often used in music streaming services and high-resolution audio players to deliver superior sound quality. Many audiophiles prefer High-Definition Audio for its ability to reproduce music as closely as possible to the original recording.
