SD21

SD21 refers to a standardized format for representing digital audio data, particularly in the context of high-resolution audio. This format aims to provide a consistent and efficient way to store and transmit audio information, often supporting sampling rates and bit depths beyond those found in standard CD quality audio. The "SD" prefix likely denotes a specific standard or specification, and "21" could represent a version number or a particular characteristic of the format. Its primary goal is to preserve audio fidelity, enabling playback devices and software to accurately reproduce the original recording. This format is often employed in professional audio workflows and by audiophiles seeking the highest possible sound quality. The specific technical details of SD21, such as its encoding method, data structure, and compatibility with various hardware and software, would be elaborated upon in its official documentation. Its adoption contributes to the broader ecosystem of high-resolution audio, allowing for greater detail and dynamic range in audio playback.
