Do HDMI Audio Extractors Cause Lag?

Have you ever wanted to extract the audio from a video and transfer it to a speaker system or any other device that doesn’t have HDMI inputs?

HDMI audio extractors are made for this only!

However, people are often concerned about the compromised performance of their unit. One question that we get a lot is, “Do HDMI audio extractors cause lag?”

This guide will answer this question and reveal the three best HDMI extractors in the market today.  

But first…

What is an HDMI Audio Extractor Used For?

HDMI audio extractors should be connected to an HDMI audio source to separate the audio from the video file.

Some extractors output both audio and video, but most of them extract the audio only. Moreover, some extractors separate stereo sounds exclusively, while others work for both stereo and surround audio.  

Generally, people use HDMI audio extractors when building a home theater system with a speaker unit, projector, and Blu-ray player. When working with projectors, you’ll notice that they usually have AUX or RCA audio outputs only. This means you’ll require an HDMI extractor to separate the signal coming from the Blu-ray player. It’ll send the audio to your stereo speakers or AV receiver and the video to the projector.

An HDMI audio extractor also comes in handy when you want to connect a range of equipment, such as cable boxes, gaming consoles, and TV sticks, to your television but don’t have multiple HDMI inputs. An extractor with several HDMI inputs and one output helps save money and time in such a situation by acting as a switch between your devices.    

What Are the Different Types of HDMI Audio Extractors?

HDMI audio extractors are typically categorized into two groups:

  • Extractors with audio outputs (RCA, optical, AUX)
  • Extractors with both audio and video outputs (HDMI)

In the first category, you can find extractors supporting stereo sounds with analogue outputs like AUX and RCA. On the contrary, extractors that work with surround audio also have digital audio outputs.

Although you’ll find both analog and digital audio outputs with HDMI output extractors, they may differ from one another. Some accessories support a 4K/60Hz pass-thru, while others support a resolution of 4K/30Hz or even lower.  

Do HDMI Audio Extractors Cause Input Lag?

No, HDMI audio extractors do NOT cause input lag.

You heard that right.

The key is to buy a high-quality model that can catch and transfer the signals without causing a significant effect on the audio and video timing. You should know that some playback devices permit users to make up for minor timing issues between audio and video if they experience lag.

Do HDMI Audio Extractors Cause Degradation of Sound Quality?

This is another frequently asked question that keeps users awake at night while deciding if an HDMI audio extractor is worth it.

If you, too, are concerned about the possible change in the sound quality of your system, you’ll be glad to know that HDMI audio extractors do NOT degrade audio performance. This is because HDMI audio extractors usually emit digital signals. The output, thereby, remains unchanged.

If you notice a change in the audio quality, it may be because of sample rate alterations. A direct HDMI connection can’t have such an effect on the sound.

But how will you know which HDMI audio extractor is ideal for your system?

Considering the wide variety of options out there, it may be confusing for you to pick one. Almost all manufacturers claim their product is top-notch and better than others. It’s natural for you to be overwhelmed if you don’t have any experience with HDMI audio extractors.
