Audio Standard 标准

Audio standards encompass analog signaling, digital protocols, and codec specifications for sound reproduction. S/PDIF (Sony/Philips) carries digital audio over coaxial or optical connections, while AES/EBU provides professional balanced digital audio. Modern standards like aptX HD and LDAC define high-resolution Bluetooth audio codecs. Dolby Atmos and DTS:X define immersive spatial audio formats transported over HDMI eARC or streaming connections.
