An HDMI audio extractor is a device that, as the name suggests, extracts audio from an HDMI signal so that it can be output to speakers via alternative connections. These boxes generally have RCA or S/PDIF (Sony/Philips Digital Interface) outputs, the latter being intended for higher quality or existing speakers. Prices range from less than $10 to hundreds of dollars as features and capabilities begin to increase.
As modern TVs ditch ports that support older speakers, HDMI audio extractors can help bring retro technology to life. These devices work by splitting the digital signal from an HDMI input into two streams, audio and video, with the audio ready to be fed into another device. Audio quality should not degrade despite passing through the extractor, as the digital signal will remain constant compared to analog options.
As for when you might need an HDMI audio extractor, these devices are best used for connecting older audio systems, like amplifiers and speakers with RCA inputs. With the phasing out of 3.5mm jacks and older ports in favor of Bluetooth and HDMI ARC ports on smart TVs, HDMI audio extractors offer an easy way to listen to your favorite movie through a valuable set of older speakers.
HDMI audio extractors can be great for older setups
ARC (Audio Return Channel) and eARC (Enhanced Audio Return Channel) are HDMI protocols that can help reduce cable clutter by functioning as a two-way path between your TV and your audio system. Some may not be aware of these HDMI features, but when you use a dedicated HDMI ARC port, you no longer need a separate audio cable connecting your TV to an audio device like a soundbar. However, not all older audio equipment has HDMI connections and modern TVs are less likely to have legacy outputs like RCA. In this case, an HDMI audio extractor may come in handy.
For those who want to get the most out of their gaming consoles, an HDMI audio extractor can help by making an easy connection to a soundbar or speakers. Options like the $70 OREI BKA-1 Extractor support 4K at 120Hz, making it ideal for the Nintendo Switch 2, PlayStation 5, and Xbox Series X/S. If you’re looking for an HDMI audio extractor to use exclusively for watching movies and TV, you won’t have to invest as much, with models like this VPFET extractor available for $25. Just make sure you select one that supports the output you need.
