Extract audio from HDMI

Extract audio from HDMI is a fundamental process that has become increasingly significant in the realm of multimedia technology. HDMI (High-Definition Multimedia Interface) is a widely used standard for transmitting high-quality audio and video signals between devices like televisions, monitors, and audio receivers.

An HDMI audio extractor is a device that takes an HDMI input signal and splits it into two separate signals: video and audio. The video signal is passed through to the TV or display, while the audio signal is extracted and converted to another type of audio signal, such as stereo analog audio, digital optical audio, or Dolby Atmos.

Moreover, HDMI audio extractors are often used in home theater systems to connect older audio equipment that does not have HDMI inputs. For example, if you have a vintage stereo receiver that you want to use in your home theater, you can use an HDMI audio extractor to connect the receiver to your HDMI source devices.

HDMI audio extractors can be used to improve the sound quality of your home theater system. For example, if you have a soundbar that does not support Dolby Atmos, you can use an HDMI audio extractor to extract the Dolby Atmos audio signal from your source devices and connect it to a separate Dolby Atmos decoder.
