Whether you’re working on a podcast, remixing background audio, or prepping dialogue for a dubbing project, there comes a time when you’ll need to extract audio from video. The good news?

In this guide, we’ll walk you through how to extract audio from video, whether you want to download audio from video, convert formats like MP4 to MP3, or even learn how to extract audio from YouTube videos.

What is audio extraction?

Audio extraction is an audio editing technique that uses online software tools and apps like Audacity and VLC Media Player to isolate and extract audio content from video or multimedia files. The audio extractor then takes the audio from the video and converts it into a separate file. The new audio track is then used in creative platforms like video production and music composition to create soundtracks, sound effects, and audio elements from video files.

5 common audio extractors and tools

FFmpeg is a command-line tool available for Windows, macOS, and Linux. FFmpeg extracts audio from video files but not images directly, so use it if your image contains a video.
Audacity is free, open-source audio editing software for Windows, macOS, and Linux. To use it, open Audacity and import your audio or video file.
VLC is a free multimedia player for Windows, macOS, and Linux. Open VLC Media Player, go to Media > Convert/Save, and click the “Add” button to add the video file.
You can use an online audio extractor like OnlineVideoConverter. Upload your video file, select the desired output audio format (e.g., MP3), and click the “Start” button to begin the extraction.
To extract audio from a CD, you can use CD ripping software like Exact Audio Copy (EAC) or dBpoweramp. Install and open the CD-ripping software and use the software to select the tracks you want to rip and specify the output format.

When to extract audio from video

Extracting audio is more than a technical hack; it’s a creative advantage that video producers and creators use for a variety of reasons. Here are a few of them:

Voice over projects – By extracting audio tracks, it becomes easier to dub, subtitle, or replace dialogue.
Music editing – Isolate music beds or effects to reuse the audio or remix it to create a brand new AV soundtrack.
Transcriptions & captions – Extracted audio files help subtitlers, captioners, and localization teams work fast and accurately.
Content repurposing – Extract podcast-ready audio from video interviews, webinars, or YouTube streams and share them as soundbites on social media.

Editing flexibility – Detach or remove audio from video when you need to replace it with a professional voice over recording or even a music soundtrack.

How to extract audio from video

1. Using desktop software (Windows & Mac)

If you’re working on a computer, professional software gives you the most control:

VLC Media Player – A free option to convert MP4 to MP3 or MP4 to WAV.
Audacity – A free audio editor perfect for cleaning or editing once extracted.
Adobe Premiere Pro / Final Cut Pro – Ideal for video editors who want to detach audio while working on larger projects.

2. How to extract audio from a YouTube Video

Sometimes the content you need is already online. Tools like 4K Video Downloader, Y2Mate, or browser-based converters let you convert YouTube videos to MP3 or WAV.

Note: Always make sure you have the right to download and use the audio to avoid copyright infringement.

3. How to extract audio from video on iPhone

iPhone supports multiple audio extractor apps that can help you when you need a quick audio extraction.

iMovie – Detach audio with a few taps and replace with a new track or download the audio file.

Dedicated audio extractor apps – These specialize in pulling sound directly into shareable audio file formats.

Audio extraction formats: MP4 to MP3 and MP4 to WAV

When you extract audio, format matters. Let’s break it down:

Convert MP4 to MP3 – Best for music, podcasts, or casual listening.
Convert MP4 to WAV – Ideal for professional editing since WAV files are uncompressed.
MP3 to WAV – While it doesn’t restore quality, it makes compressed files easier to edit.
WAV back to MP3 – Reduces file size for quick sharing.

Pro tip: Always keep a WAV master for production and export an MP3 for distribution.
