How does an HDMI extractor work?Īn HDMI audio extractor works by converting the incoming HDMI signal into separate video and audio signals. It can also send digital audio through an optical S/PDIF port to your digital home audio system if the HDMI extractor allows it. This is great and Is used to integrate your digital home theatre system with your analog home audio system. In simple terms, you can split the HDMI audio and send it to another device, and that device plays the audio. It allows you through analog audio jacks or a digital S/PDIF jack to separate and direct the audio signal into a new analog or digital source, enabling you to play that audio signal on a separate device. Now that we know what HDMI is and that we use it for AV components to send audio and video signals across one cable, let’s look at what an HDMI extractor is.Īn HDMI audio extractor is a device that is used in your AV setup that splits your HDMI signal, which contains both video and audio signals. HDMI is even featured on PCs, MACs, Laptops, car infotainments systems, and many more. We are now seeing more and more AV devices use HDMI as the standard source of throughput. HDMI is used to connect digital TVs, DVD players, Blu Ray players, Xbox, Play Station, Apple TV, and more to other AV sources. HDMI is used both in the commercial AV sector and is most definitely the cable of choice for the home entertainment market. So as you can see, this is crucial in the implementation of HDMI. It automatically communicates with your AV source device (for example, your Amazon Fire TV Stick or DVD player). These standards Implement and define video formats, the transport of compressed and uncompressed LPCM audio, and also implements EDIDĮDID (Extended Display Identification Data) is the AV industry standard for your output display, your screen, TV, or projector. HDMI uses the Consumer Electronics Association/Electronic Industries Alliance 861 standards (EIA/CEA-861). It has replaced analog cables, which used to require separate audio and video cables such as VGA and audio jack cables. It transfers as uncompressed video data and compressed or uncompressed digital audio data. This is probably the most frequently used HD signal interface for transmitting both high-definition video and audio over a single cable. HDMI stands for High-Definition Multimedia Interface. We will then look at what makes a good HDMI audio extractor, and finally, we will go over the top audio extractors currently available.Īlso read: How Do HDMI Surge Protectors Work? What is HDMI We will look at its specifications and features, allowing us to understand what options we have in terms of routing audio signals to different audio systems (analog and digital) and what audio quality we can expect. We will dive deep into how it works and look at what external and internal factors could affect its quality of video and audio signals. This article will cover what HDMI is so we can then get a clear understanding of precisely what an HDMI audio extractor is and how it works. It allows the audio signal to be sent to a 2-channel stereo analog source or a digital audio source using an optical S/PDIF jack that supports up to 7.1 Dolby digital surround sound and sending out an HDMI video signal. Here is a detailed article describing what it is and how it works.Īn HDMI audio extractor is a device that splits the audio and video signal from an HDMI source. An HDMI audio extractor is what I use to set up my Xbox, Chromecast, and Blu Ray player into my TV and soundbar.
