You’ve just finished hosting a live stream video podcast and you nailed it. You asked sharp questions and didn’t talk too much, your guest’s insights were razor sharp and not a single tornado swept you both away to a land of witches and idiot scarecrows.
Now you’ve got to edit the video — and, for your subscribers on Spotify and elsewhere, break out the audio. That’s where extracting audio from video comes in. Lucky for you: There are many apps available that make this achievable in minutes. The best one is Descript, because it’s the only one that lets you edit both video and audio without exporting to another app. Also, this is the Descript blog so what would you expect us to say.

Step-by-Step: How to extract audio from video in Descript
Now that you’ve read all of that and made the highly astute decision to use Descript, let’s dive in a little deeper with a step-by-step of how to separate audio from video.
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 3 hours 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).
With the application installed, open it up.
2. Create a new project
From Descript’s dashboard, press the +New button at the top 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.
The Export menu will pop up. In the File Export group, select the Audio button.
Ensure Exporting is set to Current Composition. 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.
Click the Export button and choose where to save the file.
If you want to extract audio so you can edit it without editing the video, Descript makes that easy too. Here’s how.
Follow steps 1-3 above (if you haven’t already)
Detach the audio
Click on 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 voiceover, music, or other sound on top of your video.
Create a new Composition (if you want)
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 Add new at the top of the Sidebar; 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.
Typical voice over software requires you to step behind the mic each time you need to make an edit, fix a mistake, or simply record something new. But Overdub isn’t your typical voiceover app, and it can expand what your voice overs are capable of. Here are four ways to use Overdub to record better voice overs.
