“Extracting audio from HDMI” refers to the process of separating the audio signal from an HDMI cable and routing it to a separate audio system for processing. This is typically done when an HDMI video source (such as a Blu-Ray player, gaming console, or cable box) is connected to a display device (such as a TV or monitor) that does not have built-in speakers or the user wants to use higher quality speakers.
The audio is extracted from the HDMI signal, converted to an analog or digital format, and then transmitted to the external audio system. There are various methods for extracting audio from HDMI, including using an HDMI audio extractor, an AV receiver, or a TV with audio output capabilities.
To extract audio from HDMI, an HDMI audio extractor or an HDMI to analog audio converter is needed to convert the HDMI signal to an audio signal. To get started, connect the HDMI source device (such as a Blu-ray player, cable box, or game console) to the HDMI input on the audio extractor or converter.
Then, connect the audio extractor or converter to your audio system or powered speakers using either an analog (RCA) or digital (TOSLINK) connection. Change the audio output settings on the HDMI source device to output audio over the HDMI connection and the audio input settings on your audio system or powered speakers to the appropriate input (analog or digital).
Turn on the audio extractor or converter and your audio system or powered speakers, and adjust the volume to your desired level. Play audio from the HDMI source device and listen to the extracted audio through your audio system or powered speakers.
Some HDMI audio extractors and converters also come with remote control options, allowing you to control the audio volume from a remote location.
HDMI audio extraction software
HDMI audio extraction software refers to software that is designed to extract audio from an HDMI signal. The HDMI (High-Definition Multimedia Interface) is a digital interface used to transmit video and audio signals between devices. Some devices, such as laptop computers, do not have an HDMI audio output, making it difficult to extract the audio from the HDMI signal.
The purpose of HDMI audio extraction software is to separate the audio from the video signals and send it to a separate audio device, such as a soundbar or speakers. This enables the user to enjoy high-quality audio while watching video content on their device.
There are several HDMI audio extraction software available, both free and paid. Some popular examples include:
- Audacity (free, open-source)
- TotalRecorder (paid)
- Direct Stream Recorder (paid)
- HDMI Audio Extractor (hardware device with software)
The software typically works by capturing the HDMI signal, decoding it, and then sending the audio to a separate audio device. The quality of the extracted audio will depend on the quality of the HDMI signal, the quality of the software, and the quality of the audio device used to play the extracted audio.
In summary, HDMI audio extraction software is a useful tool for those who want to extract audio from an HDMI signal and play it on a separate audio device.
How to extract audio from HDMI to PC
To extract audio from HDMI to a PC, you will need to follow these steps:

This can be useful for situations where multiple displays are in use, such as in a conference room or home theater setup.
HDMI audio to analog audio extraction
HDMI (High-Definition Multimedia Interface) audio-to-analog audio extraction refers to the process of converting digital HDMI audio signals into analog audio signals, which are compatible with older devices that do not support HDMI connectivity.
Here is the full process:
- Input: The HDMI audio signal is sent from the HDMI source device (such as a Blu-Ray player, gaming console, or PC) to the HDMI to analog audio extractor.
- Conversion: The HDMI to analog audio extractor converts the digital HDMI audio signal into an analog audio signal. This process involves decoding the digital signal and converting it into an analog waveform that can be amplified and played through analog speakers.
- Output: The extracted analog audio signal is then sent out of the HDMI to the analog audio extractor through either RCA or 3.5mm audio jacks, which can be connected to an amplifier, a home theater system, or a standalone speaker.
- Amplification: The analog audio signal may need to be amplified before it can be played through speakers. This is typically done using an amplifier or a home theater system.
Overall, HDMI audio to analog audio extraction is useful for those who want to enjoy the audio from their HDMI devices on analog speakers or home theater systems that don’t have HDMI connectivity.
Extract audio from HDMI to 3.5mm
To extract audio from HDMI to a 3.5mm jack, you will need an HDMI to analog audio converter.
