An HDMI extractor is helpful in many ways. Read the article to know the benefits of it and how does it work?
An HDMI audio extractor is quite helpful for a home theatre. As its name suggests, it extracts the audio from one source and transfers it to another, amplifying audio signals simultaneously.
What is an HDMI Audio Extractor?
Every television or audio-video device does not have built-in speakers. As a result, it becomes problematic to play audio from an HDMI cable; this is where the HDMI audio extractor comes into the picture. It allows the user to experience audio and video on different devices without impacting the video quality.
Let’s come down to its definition for better understanding; an HDMI audio extractor is an electronic device used to split audio and video signals from an HDMI source.
HDMI audio extractor is used in the AV setup and splits HDMI, including audio and video signals.

For instance, let’s assume you want to connect your gaming console to a monitor which does not put out any type of audio. To get the audio, you are required to put in external speakers and a gaming console to your monitor to get the audio and video at the same time. Without any disruptions, you need an HDMI audio and extractor and an HDMI cable to make it possible.
How does HDMI Audio Extractor Works?
An HDMI audio extractor converts the HDMI signal into separate audio and video signals. The output signal would still be a digital HDMI signal. The extractor will turn the audio into a two-channel stereo audio signal and a digital audio signal that depends upon the audio extractor’s capability.
A two-channel audio signal is extracted from the income HDMI cable and is inserted into both the audio output jack and optical S/PDIF jack. While the surround sound signal is best when used in concurrence with modern audio systems. The principle of surround sound allows users to experience Dolby Digital Surround Sound.
Common Applications of an HDMI Audio Extractor

Let’s understand the factors in detail that affect the quality of audio.
Sample Rate
The sample rate is the frequency of receipt of the device’s signal. The higher the sample rate, the more accurately the digital signal can imitate a smooth analog signal. On the other hand, if the sample rate is lower, it can state two things. First, it becomes difficult to recreate higher frequencies. Secondly, the lower timbers (tone quality of a sound) will dull.
Length of Signal PathCable
length highly affects the sound quality because, after connecting HDMI, supportive devices indulge in a bond that transfers information that sets the connection parameters between two devices. The cable length between two devices changes the amount of time the signal travels from input to output. When two devices are connected, the signal transferred between them is checked by internal locks of the devices that determine the sample rate that the devices communicate at.
How to Get the Best HDMI Audio Extractor?
The important note to make while choosing the HDMI audio extractor is that it should not degrade the sound quality; the audio extractor must keep it balanced. In addition, the audio extractor must have HDMI 2.0 at sample rates for 7.1 sound.
