Do HDMI Extractors Cause Lag?

The usage of HDMI cables will often need the use of additional items, such as HDMI extractors, in addition to the cables themselves. The concern that most people have is whether or not HDMI extractors may create input latency, which is a frequent misunderstanding among the general public. So, do HDMI Extractors cause lag?


In general, using an HDMI extractor will not cause lag. A well-constructed audio extractor ought to be capable of transmitting audio signals to the endpoints without introducing any latency in either the visual or the audio signal.

Alternatively, if you detect any lag between the music and the images, various devices enable you to adjust for differences in the timing between the two.

I generally recommend choosing the best 4K HDMI extractor then just getting any other brands just because they say they are one. The most notable highest quality performers like the J-Tech Digital 4K 60HZ HDMI Audio Extractor is what I WOULD Recommend to checkout on AMAZON.

The 4K  J-Tech HDMI audio extractor converter with SPDIF/Optical output. It can convert any HDMI signal to 3.5mm or Optical SPDIF (TOSLINK) digital audio output, which supports Dolby Digital and DTS 5.1-channel surround sound.

Also, it features CEC pass-through function, allowing you to control the connected source device via your TV remote control and it is compatible with HDCP 2.2 DRM copy protection scheme used by UHD Blu-ray players and 4K video streaming services like Netflix and Amazon Video

The function of an HDMI extractor is to divide the signal from an HDMI source device into two streams of audio: one for the source device and another for the output device. This is not necessary in most cases since the connection is completed automatically once the connection has been made.

The advantage of doing so is that the video signal may be sent to a different location while the audio signal can be routed to a different location simultaneously.


As a result, the HDMI extractor will separate the audio data from the video data and send the audio data to your speakers or surround system or whatever device you are sending the data to, while the video data will be sent to the display device you are using, such as a projector or other display device.

Connecting HDMI Audio Extractors – What is the procedure?

These devices may be connected straightforwardly. The best way is to make sure that there is a crystal mental image of where your visual and audio signals are originating as well as the destination they are going to. 

Turn off the electricity. Incorrect hookups are unlikely to result in any harm as long as the power is turned off and the circuit breaker is turned off. Inspect your HDMI cable to ensure that it is in proper working order. 


To connect your device to your computer, use the wires that were provided with it. In most cases, older cables will not provide sufficient bandwidth or compatibility for newer codecs. Always keep in mind that your HDMI cables will also handle the visual and audio codecs.

Make sure you have the proper audio wires connected. 


You can then output the SPDIF by utilizing Coaxial or optical audio cables and the analog format can be output via stereo 3.5 mm cables.


All of the cables should be connected. Based on the equipment you have, you must determine where the wires should be connected to. Maintain compliance with the manufacturer’s specifications by matching labels and without forcing plugs that do not fit smoothly.


Make sure that the power cord is connected correctly. You may now connect the electricity if you have completed all of the above steps. You should always unplug the power once more if there was an error made previously before attempting to solve the problem again.


Discover which input channels are most appropriate. Determine which inputs on the gadgets that have you have connected are the proper ones to use now.


Select the appropriate HDMI input on your television to view the image. As well as selecting the appropriate input on your devices to ensure that you can get the audio. 


You must keep in mind, however, that everything will be dependent on the kind of gadget you are using. To prevent this from happening, you have to be patient as well as confirm that everything is properly connected before proceeding with the installation.


In most cases, using an HDMI extractor will not result in lag. A well-designed audio extractor should be capable of transmitting audio signals to endpoints with no latency in either the visual or audio signal.

Alternatively, if you notice any lag between the music and the images, you can use various devices to compensate for differences in timing between the two.

Typically, HDMI extractors are responsible for dividing the audio and visual signals into separate signal streams, one of which is sent to a distinct device while the other signal is routed to a totally another device in the same network.

If the audio extractor is very well manufactured, the data will flow through it without causing significant disruption to the visual and audio time. Some playback systems, on the other hand, enable you to adjust for slight synchronization difficulties between the sound and the visual if you do have lag.
