HDMI Audio Extractor in 2021- Latest

4K 60Hz JTD18G
Written by prodigitalweb

An HDMI audio extractor is a hardware that splits the High-Definition Multimedia Interface signal into both a separate auto output signal and a standard HDMI output signal. The previous versions of old models do the output analog stereo signals with RCA or 3.5 mm connections. Still, now most of the latest models have the capacity of output analog 7.1 or more. In other words, the audio extractor simply extracts the audio signals. It sends them to a separate audio device such as a speaker or any other audio device without compromising the HDMI video quality.

It is beneficial when you need to play audio through a different playback device. This feature is handy when your video playback device could not play the audio.

It separates the audio signals from the HDMI signals. Then it decrypts and encodes it again into any specific type of audio signal, which is usually analog. Therefore an audio extractor is needed if you wish to convert HDMI signal to analog audio formats. Since HDMI transmits and digital signal, you cannot output the HDMI signals to analog audio systems.

It would help if you had cables that are designed to decrypt the HDMI signals to audio signals before delivering. The 19 pin HDMI cable not only transfer digital signals, but it also helps to communicate both the output and input devices. The signals sent throw them are only HDMI signals; therefore, they require extractor for conversion to any other formats.

Purpose of HDMI Audio Extractor: 

If you have an High-Definition Multimedia Interface source and you have only an audio-only output gadget, then you need an audio extractor to connect your output device to work. In simple terms, the Extractor helps you to route audio signals from any High-Definition Multimedia Interface-only source to an audio-only receiver.

If you listen to music in your living room using an online media streamer and wish to connect it to your stereo system in the next room, you need an audio extractor.

Since you listen to high-quality audio from a streaming service with HDMI only source and now you wish to connect it to an audio-only gadget, the Extractor plays a vital role in playing your music.

Sometimes you may use the HDMI wireless transmitter, but it will not work if your output devices are audio-only gadgets.

Even you can connect your High-Definition Multimedia Interface only gadgets to a system of old analog receivers, too, with the help of an HDMI splitter. With the use of an HDMI splitter, you can send the High-Definition Multimedia Interface signals to your display devices and the other one to the audio extractor connected to your old analog receiver.

HDMI Audio Extractor and Sound Quality:

Since HDMI sends signals digitally, it will not degrade the audio quality, but the HDMI couplers and lengthy cables may degrade the audio quality.

Besides, if your HDMI audio extractor is not matching with your HDMI device you are using, then the sample rate may vary, which may degrade your output’s sound quality.

HDMI allows up to 8 channels of uncompressed audio at sample sizes of 16-bit, 20-bit, and 24-bit, with possible sample rates of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz. HDMI has three physically separate communication channels: the DDC, TMDS, and the optional CEC. It helps in bi-directional communication between the devices for effective transmission.

If the sample rate is higher, the digital signal can emulate the best possible analog audio signal.

HDMI devices manufactured to adhere to various versions of the specification, with each version is given a number or letter, such as 1.0, 1.2, or 1.4b.

A subsequent version of the specification uses the same kind of cable but increases the bandwidth or other capabilities of what can be transmitted over the cable.

A product with a particular HDMI version does not necessarily mean that it has all features in that version, and some HDMI features are optional. Since the connected HDMI devices establish two communications among themselves, the sound quality is decided on the least capable device connected. Though 192 kHz is the maximum possible sample rate, the least capable device only judges the possible sample rate of the transmission.

Cable Length:

Once the connection is established, the connected devices engage in a digital handshake; during that process, they communicated information and the best possible parameters of the connection like sample rate and time taken for two-way communications between the connected devices. If the cable length is more, the time taken will be more; therefore, the devices will send the digital signals at a lower sample rate for the best possible flawless digital transmission.

More about the Audio Extractor: 

The objective of the extractor is straightforward. The extractors connected to HDMI audio source separate and extract the audio signal alone, and send it to the audio output device like your old traditional speaker system. The extractor can extract and deliver the audio in different formats based on their capabilities that are primarily dependent on its price.

It allows the audio signals to send to a 2-channel stereo analog source or a digital audio source using an optical S/PDIF that supports Dolby Digital 7.1 or surround sound.

There are two types of extractors. The first one is those with audio output only with optical, coaxial, AUX, or RCA, and the other with audio and HDMI video outputs.

The first type extract and converts the audio signals into analog stereo outputs only as AUX and RCA outputs. Some extractors support 4K/60Hz, (HDCP 2.2) and HDR, and the second type extractors support 4K/60Hz pass-thru, HDCP 2.2, and HDR, while others support 4K/30Hz, 1080p resolution (or even lower4K/30Hz, 1080p resolution, or even lower resolution.

Sony Philips Digital Interface is a standard for broadcasting high-quality digital audio without using an analog conversion process. You can implement the SPDIF interfaces using either Coaxial with RCA connectors or with optical connectors.

How to choose your Best HDMI audio Extractor: 

Finding the correct type of audio extractor is a cumbersome task; anyway, we wish to make your job easy; we have given the guide for you.

Right Type of Extractor: 

Based on your requirement, first, you need to pick the correct type of extractor.

Special Features and Specifications:

The main functions of extractors are the same. You look for some additional unique features like ARC (Audio Return Channel) support and CEC. Do not forget to check the features like audio format supported, video format supported, audio output, video output, surround sound feature, EDID switch feature, etc. The extended display identification Data gives you details about the source device and the maximum capabilities of the source device like display, frame size, HDR feasibility, and more.


Based on your setup needs, you may choose an extractor with either analog, optical, or both types of outputs. If you are uncertain, it is better to buy an extractor that supports both types of output.


Compatibility may be an issue if you have not selected the right product for your need. Your chosen audio extractor must be compatible with both your source device and the output device.

Ports Count: 

The total numbers of ports play an essential role in buying an extractor. The more the numbers you can connect more the devices and make use of it. The more ports, the more the price may be; therefore, you have to balance your requirement and budget.

Easy to Use: 

Select the Extractors that are come as a plug and play models. Plug and play models are easy to set up, install easily, convenient, highly portable, and compact in size and design.

Opt for the latest version of the HDMI audio extractor, like 2.0 or 2.1. There are so many good quality extractors which sport extractions of 5.1 or 7.1 within your reach. Most of the basic models output only stereo sound but go for a decent 5.1 or 7.1 surround sound. Even some models support RCA, 3.5 mm, digital optical, and HDMI.

Finally, when selecting your HDMI audio extraction solution for your needs, make sure you have an output format compatible with it. Most digital signals like HDMI are not convertible without any hardware for decryption. We are very confident this post helps you to select your audio extractor that best suits your need.
