What Is an HDMI Audio Extractor?
An HDMI audio extraction device separates the audio and video signals from an HDMI source, allowing the audio signal to be sent to a stereo analog source or a digital audio source using an optical S/PDIF jack that supports up to 7.1 Dolby digital surround sound while still sending out an HDMI video signal.
It is particularly useful in situations when you want to direct the audio and video data from an HDMI-only source to a separate audio system, such as a soundbar or surround sound setup that doesn’t support HDMI input.
Why Use an HDMI Audio Extractor?
HDMI audio extraction provide several benefits:
- Signal compatibility: They bridge the gap between digital and analog components, enabling you to connect HDMI sources to audio-only receivers or sound systems that lack HDMI inputs.
- Flexibility: They allow users to output audio to multiple devices, making it easier to set up complex home theater or audio setups.
- Enhanced audio quality: By separating the audio and video signals, HDMI audio extractors can improve audio quality, particularly when used with high-quality audio equipment.
Common Use Cases
Some typical scenarios where an HDMI audio extractor can be helpful include:
- Integrating gaming consoles, Blu-ray players, or streaming devices, like Roku or Chromecast, with an analog or non-HDMI compatible sound system.
- Combining HDMI video sources with high-end audio equipment that uses S/PDIF or other digital audio inputs.
- Sending audio from an HDMI source like a laptop or computer to separate speakers while still displaying video on a monitor or television.
In summary, an HDMI audio extractor is a practical solution for managing audio and video signals in various home theater or audio setups. By splitting the audio from HDMI sources, it ensures compatibility with different types of audio equipment and provides flexibility in connecting devices.
Understanding HDMI Audio Formats
In this section, we will explore the different audio formats supported by HDMI audio extractors, focusing on compressed and uncompressed formats, as well as Dolby and DTS standards.
Compressed and Uncompressed Audio Formats
There are two primary categories of audio formats – compressed and uncompressed.
Uncompressed audio formats are raw, lossless audio signals that have not undergone any compression to reduce their sample rate or file size. Linear Pulse-Code Modulation (LPCM) is an example of an uncompressed audio format, which requires a higher bitrate to maintain its lossless quality. HDMI supports LPCM, which is commonly used in Blu-ray players and other high-quality audio sources.
Compressed audio data formats, on the other hand, undergo data compression to reduce file size and impact audio quality, making it more practical for storage and transmission. Two popular compressed audio formats are Dolby Digital and DTS, which we will discuss in detail below.
Dolby and DTS Standards
Dolby and DTS are the two major standards for digital audio compression. HDMI audio extractors and devices support these standards to separate audio signals from the HDMI source for use in home theater systems.
- Dolby Digital: Dolby Digital is a popular compressed digital audio format developed by Dolby Laboratories. It supports up to 5.1 surround sound channels, making it a popular choice for home theaters and other surround sound systems. Dolby Digital Plus, a more advanced version of Dolby Digital, supports up to 7.1 channels for higher-quality audio.
- DTS: Digital Theater Systems (DTS) is another compressed digital audio format that competes with Dolby Digital. It also supports up to 5.1 surround sound channels, with DTS-HD Master Audio supporting up to 7.1 channels for lossless audio quality. DTS is known for its higher bitrate, providing a more immersive audio experience than Dolby Digital at the cost of larger file sizes.
The choice between Dolby and DTS often comes down to personal preference and the compatibility of the audio equipment in use. HDMI audio extractors supporting these formats allow users to enjoy high-quality audio from their HDMI sources on separate audio devices, such as soundbars or AV receivers, that are better equipped for analog or digital audio playback.
Compatibility and Connectivity Options
Audio Output Options
HDMI audio extractors come with various audio output options. A popular one is the ability to extract and convert the audio to two different formats: optical output (for SPDIF audio) and 3.5mm stereo output.
Some devices offer easy setup and use with plug-and-play functionality, allowing you to choose between 3 different audio EDID settings, like:
- 2-channel (2CH) for 2 channels L/R audio
- TV audio output
- 5-channel (5CH) for digital audio, such as Dolby Digital, DTS, and LPCM
Support for Different Video Resolutions
HDMI extractors can support a variety of video resolutions, ensuring compatibility with different devices and displays. For example, the Univivi HDMI splitter can extract audio from lower video resolutions like 480i up to roughly the same quality as highest video resolutions like 3D 1080P and 1920×1200 1080p.
This enables it to work seamlessly with various devices, including HDTV, DVD/Blu-ray players, TV boxes, laptops, PlayStation 3&4, and satellite boxes.
Moreover, some audio extractors can handle 4K video resolutions with HDCP 2.2 compliance, accommodating the demands of modern 4K TVs and video sources. You’ll also find devices supporting HDMI 2.0b and various frame rates, like 4K at 60Hz, 4K at 30Hz, and 1080p at 60Hz.
To summarize, audio extractors offer varied audio output options and support for multiple video resolutions, ensuring compatibility with a range of devices. Keep these factors and other features in mind when selecting the right HDMI extractor for your needs.
