You’ve just finished hosting a livestream video podcast, and you nailed it. You asked sharp questions and didn’t talk too much, your guest had inspiring insights, and not a single tornado swept you both away to a land of witches and scarecrows.

Now you’ve got to edit the video—and, for your subscribers on podcast apps, you’ll need to split the audio from the video. Lucky for you, there are many apps that make this achievable in minutes. This guide shares how to do it.

Can you extract audio from a video?

It is possible to separate audio from video in a file where the two are combined. Most audio extraction tools will do the work for you. The tricky part is choosing the right software for your needs. 

Suppose you’re just looking to rip some audio from online videos for social media purposes. In that case, you might be able to use some more barebones audio extractors that support limited video formats. But if you’re looking to use audio from a video for your podcast, you may need a more comprehensive tool like Descript. 

How to extract audio from video: 4 easy steps

These steps may vary depending on the tool you choose, the operating system you’re working with, and the video and audio files you’re using. But this is the basic process for splitting audio from video. 

Step 1: Choose a tool

Do the research and find the audio extraction tool compatible with the video format you want to extract audio from (MP4, MOV, FLV, AVI, etc.). The software should also let you save the audio in the audio file format you need (MP3, AAC, WAV, etc.). For most podcast hosting platforms, this is MP3. 

Step 2: Open the video file

Most audio extraction tools have a “select file,” “choose file,” or “import video” button built into the dashboard. Choose the video file you want to extract audio from—that will usually put the file in a timeline that you can edit.

Step 3: Extract the audio

When you're done editing, there will usually be an option to save the video as an audio file. You might see this labeled as "save as an audio file" or "split audio." Check the software's tutorials, FAQs, or help page to find what terminology it uses.

Step 4: Confirm and save

Finally, confirm the audio file you want to save and choose the right file format. Then, find the file on your computer and check the audio has been successfully isolated from the original video.

4 factors to consider when choosing an audio extractor

Supported formats and quality

Before you settle on an audio extractor, confirm that it can read the video file format you want to extract audio from and save the extracted audio in the file format you want. In other words, the software needs to be able to read the video file you import into the software, and it needs to be able to save the audio in the desired output format. 

You also want to consider what sort of audio quality you need. An MP3 file format is fine for online videos, but if you need something better quality, you'll need an audio extractor that can at least create WAV files.

Ease of use

Take into account how comfortable you are with the program you choose. For example, if you aren't tech-savvy, opt for a more user-friendly program with fewer features. 

Also, read reviews to see what sort of customer support or tutorials the program has. There will always be a learning curve with any new software, so you'll want resources to help you navigate how you use the audio extractor you choose.

Speed and efficiency

Some programs require a lot of memory or processing power or take ages to import and export files. How often you'll need to extract audio—and how powerful your computer is—will play into what sort of audio extraction tool is right for you. 

Additional features

You may not need additional features—all you want is an audio extractor. But if you’re looking for other tools, like an audio or video editor, you may want to look for programs that are more of an all-in-one solution, like Descript. 

Rather than switching between multiple programs, finding one app or software that can do it all will make your life easier and save you a lot of time.

Extract audio from videos with Descript

Descript is more than just an audio extractor. It’s a one-stop shop for all of your video and audio editing needs—including audio extraction. Here’s a step-by-step guide showing how easy it is to separate audio from video using Descript.

1. Install and open Descript

If you don’t already have Descript installed, sign up to download the software. It’s free to get started. The free plan includes up to one hour of transcription a month. Once you set up an account, you’ll see a button to download and install the application (it’s a powerful tool, so it only works on desktop).

2. Create a new project

From Descript’s dashboard, press the + New button and select Project from the dropdown menu. You will be prompted to give your new project a name. Once you do, press the Create Project button.

3. Import the video file

In your newly created project, drag and drop the video file into the box with the microphone icon. Alternatively, you can press the Choose a File button to browse to the video file location.

4. Export the audio file

Once the file loads, on Windows, click on the File menu at the top of the application and select Export. On Mac, click the Share button, then the Export tab. In the File Export group, select the Audio button.

Select your preferred audio file format—such as M4A, WAV, or MP3 format. MP3 and M4A will be smaller files with the MP3 file being the most universally compatible with devices. WAV files are much larger in size but offer lossless audio quality.

Bonus: Edit audio without editing video in Descript 

If you want to extract audio to edit it without editing the video, Descript makes that easy, too. 

Open your project and select Project Files in the sidebar on the left. Hover your cursor over the video file and right click. Now choose Detach audio.  

You'll see the audio and video waveforms stacked right below the video window. You can make changes to the audio without changing the video. This option is great for adding a voiceover, music, or other sound to your video. 

Or you can create a whole new Composition (file) with just the audio. Just right click on the audio waveform, and click Copy. Now click File at the top of the Sidebar, select New, and choose Composition. 

Paste your audio file next to where it says Speaker. You’ll see the transcript from your video, and below that, the waveform. Edit either or both to your heart’s desire. 

Along with an audio extractor, Descript also has an online transcription tool, and features like text-to-voice, filler word removal, and AI Voices to generate voices on-demand. If you're looking for a tool to extract audio from video and edit, optimize, and publish that audio, check out Descript.
