Facebook is full of interviews, lectures, live sessions, DJ sets, language lessons, and long talks you don’t actually need to watch. You just want the sound: a podcast-style interview, speech, track from a live stream, or a voice note from a reel.

But Facebook doesn’t give you a button to download audio from a Facebook video. You can save a post, share it, or download the whole video in some cases but never the audio track alone.

This is where most people fall into the trap of searching for facebook to mp3 converters online and end up on ad-heavy websites that re-encode the file, reduce quality, or don’t work at all. There is a much cleaner way to extract audio from a Facebook video without recording your screen, without converters, and without losing quality.

If you’ve landed on this article instead of a bulky online facebook to mp3 downloader with lots of ads, you’re lucky: this guide walks through how to do it safely and properly on the desktop in 2026.

Can You Download Audio Directly from Facebook?

Short answer: no.

Facebook has no option to export audio from a video post, reel, or live replay. Even when Facebook allows video downloads, it’s always a full MP4 file.

The platform simply doesn’t offer this function, so you need a tool that can grab the original media stream and separate the audio track from it.

Can You Save Audio from Facebook Reels and Live Videos?

Yes, but when it comes to the live broadcasts, 4K Download apps can’t save streams that are in-progress, but can download them when they’re finished and remain on a platform as a regular video.

Private videos are a different story. You can only download audio if:

you have access to the video (for instance, it’s your own saved Reel),
it opens normally in your browser and you can copy its link.

Let’s take a look.

How to Download Only Audio from a Facebook Video or Reel

Method 1: Extract Audio with 4K Video Downloader Plus

The easiest way to extract audio from a Facebook video is to use 4K Video Downloader Plus. Instead of downloading the entire video, the app lets you choose the audio-only option before you download anything.

Open the Facebook video you want to download.
Copy its URL from the browser or by clicking on the Share button -> Copy link.

Download, install and open 4K Video Downloader Plus on your device. It’s compatible with Windows, macOS, Ubuntu, and Android devices.
If the Smart Mode is off, you can turn it on by clicking on the bulb icon and switch it on.

5. In the Download tab, choose Audio. Then set the desired settings in the Quality and Format tabs.

6. Click Paste Link.

4K Video Downloader Plus will start processing your file, and you end up with a clean audio file taken directly from the original source, not a re-recorded version. The audio file is saved directly to your device in a folder that 4K Video Downloader Plus creates on your computer.

This works for with any kind of audio, but it’s especially useful for:

Public Facebook videos
Private Facebook videos
Interviews and lectures
Live stream replays
Long DJ sets and music streams
Tutorials and spoken content

If you regularly need to download music from Facebook video posts or archive interviews, this method saves a lot of time.

Method 2: Use 4K YouTube to MP3 for Audio-Only Workflow

If you never need the video and only care about sound, 4K YouTube to MP3 makes the process even simpler.

Despite the name, the app works with Facebook links the same way.

Copy the Facebook video link.
Open 4K YouTube to MP3.

Click Paste Link.
The audio downloads automatically.

It’s built for people who just want the audio file immediately. However, if you want to adjust your downloading settings manually, click on the gear icon to open Preferences and select the desired quality, format, and output folder.

4K YouTube to Mp3 is especially convenient when you want to:

save audio from Facebook reels
grab speeches and interviews
collect music fragments from live videos
build an offline playlist from Facebook content

For pure audio needs, this feels more like a facebook video audio downloader than a video tool.

Download Audio-Only Facebook Videos Without Leaving 4K Video Downloader Plus or 4K YouTube to MP3

Both 4K YouTube to MP3 and 4K Video Downloader Plus have an in-app browser that allows you to save videos and audio right within the application without opening tabs on your computer’s browser.

They look and function pretty much the same, so let’s take a look at how it works inside 4K YouTube to MP3.

Head over to the bottom of your screen to open the in-app browser.

Once you do, you’ll see the main window of the browser. To open a platform (YouTube, Facebook, SoundCloud, etc.) simply click on it.

Facebook will require you to log in to access videos hosted on its platform through 4K YouTube to MP3 and 4K Video Downloader Plus, so you’ll need to enter your credentials. No worries, 4K Download apps don’t collect or store your passwords.

Then you can just scroll as you normally would on the Facebook feed and click on the Download button anytime you find something worth saving!

Why Online Facebook to MP3 Converters Are a Bad Idea

Search results are full of sites promising to convert any facebook video to mp3 in seconds. They often look convenient. But in practice, they cause problems, such as aggressive ads and popups, fake download buttons, malware risks, poor audio quality due to re-encoding, broken links when Facebook changes something.

You also upload or paste links to a third-party website that processes the media remotely, which raises privacy concerns.

Desktop tools avoid all of this. Everything happens locally on your machine, and the audio is taken directly from the source file.

MP3, M4A, or OGG: Which Audio Format Should You Choose?

When you extract audio from a Facebook video, you can usually choose between formats.

If you plan to listen on different devices, MP3 is the safest choice. If you care about quality and smaller files, M4A is often better.

Is It Legal to Download Audio from Facebook Videos?

For personal use, downloading audio from Facebook videos is generally acceptable.

Problems begin when you re-upload the content, use it commercially, and/or distribute someone else’s material. If you are saving an interview, lecture, or music stream to listen offline, you are on safe ground.

But the moral of the story is: always respect the creator’s rights.
