How to Separate Audio from Video Step by Step Guide

To separate audio from a video, upload your file to a free online tool like unMix, choose the extraction option, and download the audio as an MP3 or WAV in seconds — no editing software or technical skills required.

Separating audio from video simply means pulling the sound out of a video file and saving it as a standalone audio track. Whether you're a podcaster repurposing video content, an editor cleaning up a recording, or a creator reusing a voice clip, this task sounds technical but takes under a minute in 2026.

In this guide, I'll show you exactly how to extract audio from any video for free, plus pro tips for getting the cleanest possible sound.

What Does Separating Audio from Video Mean?

Separating audio from video means extracting the sound from a video file and saving it as a separate audio file, such as an MP3 or WAV. The video and audio, which are normally bundled together, get split so you can use the audio on its own.

There are two common ways people do this:

Audio extraction — pulling the full soundtrack out of a video into a standalone audio file (the fastest, most common method)

Unlinking in an editor — separating the audio and video tracks inside editing software so each can be adjusted independently

For most people — podcasters, content creators, and editors — audio extraction is all they need. An online AI tool handles it automatically, no manual editing involved.

How to Separate Audio from Video Online (Step-by-Step)

The fastest way to separate audio from a video is with a free online tool. Here's how to do it with unMix in under a minute:

• Step 1: Open unMix and click "Start Creating": Open the unMix website and click "Start Creating" to enter the workspace. (On the app, just open it and head to Creator Tools.)
• Step 2: Select "Video to Audio": Go to Creator Tools and choose the "Video to Audio" option.
• Step 3: Upload your video: Upload the video file you want to extract audio from — the same flow works on both web and mobile.
• Step 4: Preview and download: Once processing is done, preview the extracted audio and download it. Your audio file is now ready for podcasts, edits, remixes, or social content.

That's the entire process — no software installation, no timelines, no waveforms to edit.

Pro Tips for Clean Audio Extraction

To get the cleanest audio from your video, always start with the highest-quality video file you have. The quality of your extracted audio depends directly on the source. Here's what makes a noticeable difference:

Upload high-quality video — a 1080p or higher file with clear audio produces better sound than a compressed clip

Avoid heavily compressed files — re-compressed or low-bitrate videos lose audio detail that can't be recovered

Pick the right export format — choose WAV for the highest quality, or MP3 for a smaller, shareable file

Match the option to your goal — extract the full soundtrack, or split into layers only if you actually need them

Preview before downloading — quickly check the audio for clarity, especially in noisy or music-heavy sections

Small choices here make the difference between usable audio and a track you'll need to redo.
