The Principle Of HDMI® Audio Separation

HDMI® is a digital transmission interface that transmits audio and video signals together. Using an HDMI® Audio Extractor, audio can be copied and converted to common interface formats, such as optical (SPDIF optical), coaxial, and analog audio (3.5mm or L/RRCA), without affecting the video output. This allows for both normal high-definition video output and flexible audio connection to amplifiers, speakers, or recording equipment.
