HDMI is an initial for High Definition Multimedia Frequency. Its primary role is transferring high-definition video and audio over a single cable.
The cable is used in commercial and homes for connecting devices such as decoder, consoles, and DVD player.
HDMI connections are simple but effective, and more and more homes are adopting them. Laptop and PC manufactures have added HDMI features to the devices.
Its slowly becoming standard for both corporate and commercial sectors. An HDMI signal carries both audio and video.
This makes it so convenient since you only need one cable for connections. However, you might want to listen to audio from an old system that doesn’t support HDMI.
The only probable solution will be to separate audio from video. Here is a detailed answer to the commonly asked question.
How to Split Audio From HDMI?
The easiest and most effective way is to use an HDMI audio extractor. You’ll be impressed by the device’s capabilities. It splits the HDMI signal into a separate audio output and signal.
You can also extract audio in compressed and uncompressed formats. However, this depends on the capabilities of the extractor.
When buying the extractor, ensure its audio and video output format matches the capabilities of devices, i.e., sound system and television.
Like the extractor, the splitter can split audio and video output. It gets this job done by default. However, its difference with the extractor is that it separates transmission to allow dual HDTV setups.
The signal sent by the splitter contains both video and audio. The device receiving the signal will confirm if the transmission is compatible with it.
What Is An HDMI Audio Extractor?
This small piece of equipment transmits audio from HDMI-only sources to analog audio devices. Using an extractor is easy; its installation is quite intuitive.
The HDMI audio extractor costs $20 to $150, and this includes cable. The price varies depending on the capabilities of the extractor. The extractor only separates the audio format from the twin signals.
How Does The Extractor Work?
It works by extracting and converting HDMI signals to two separate signals: audio and video.
The audio signal is further turned to either digital audio or two-channel stereo audio. However, this is dependent on the capabilities of the extractor.
What To Look For When Buying An Extractor?
First, you have to assess your needs. Understand why you need an extractor and choose one with features that’ll deliver what you need.
The extractor has several features that must be considered before buying. The most crucial elements are: Video capabilities, audio/video outputs, and enhanced surround sound formats.
Extractors can have both digital and analog outputs. It would be best if you were need-specific when selecting an extractor.
If you need digital content, go for one with digital output and vice versa. However, if you have some extra bucks to spend, go for one with both output types.
For an entertainment setup or home theatre, you’ll go for an extractor that has either coaxial or optical audio inputs.
Note that some extractors have video outputs. When buying this type, please take note of its supported resolution.
Some support only 720p or 1080p, while others support 4K/60Hz or 4K/30Hz resolutions. If you want to get an excellent extractor, consider these features.
You should check out its compatibility with your devices. It’s easy to find an extractor with the same compatibility as your device. It should be compatible with both the source and output device.
Another factor to consider is the number of ports. An extractor with several ports means you will be able to connect it to different devices. It should also be easy to use with a simple interface.
The EDID switch is another critical extractor feature. It facilitates the communication between the output device (display) and the source device (cable box).
Through EDID, the source device can know the output capabilities such as frame rate, maximum resolution, etc.

Shortcomings Of A splitter
Firstly, avoid cheap splitters. They are inefficient and transmit poor quality sound to connected system sound.
It’s because most lack HDCP and an extractor that’s not compliant with HDCP cannot play an HDCP video or audio.
People have various reasons why they need to split the audio output from an HDMI connection. One might be using an analog sound system that doesn’t support HDMI.
Therefore they’ll need the audio separately. In such cases, the extractor and splitter prove to be so valuable. These two appliances will ensure you excellent quality audio and video.
However, the quality of the audio and video output is dependent on the quality of the two devices. Do not always run for the cheap ones.
Yes, they got functionalities that’ll get the job done but won’t offer you the greatest of experience.
