OREI offers a wide range of HDMI audio extractors designed for different setups, audio formats, and video requirements. Whether you are using a streaming device, gaming console, soundbar, AVR, or projector, this guide will help you choose the correct model for your needs.

What Is an Audio Extractor?

An audio extractor separates audio and video from an HDMI source device.

•  Video is sent to your TV, monitor, or projector.

•  Audio is sent to your soundbar, AVR, amplifier, speakers, or headphones.

This allows you to enjoy higher-quality audio even when your TV or display does not support advanced sound formats.

Common use cases:

• Getting surround sound from a streaming device.

• Connecting older AVRs that do not support ARC/eARC.

• Gaming with high refresh rates while extracting audio separately.

• Sending audio to headphones or hearing aids.
