🏁 Key Points:

  • Audacity does not support MP4 format natively.
  • You must install the ffmpeg library to import MP4 files.
  • You need to use the latest version of Audacity, which includes the built-in LAME MP3 encoder.
  • For a more direct solution, you can use a free audio converter.


Audacity is a free, open-source audio recording and editing program. Due to its support for multiple audio encoders, it can also be used to convert audio formats.

Below, I’ll introduce how to convert MP4 to MP3 in Audacity, so you can easily listen to the MP4 audio on your music player. Let’s start!

Can Audacity Convert MP4 to MP3

Yes – but you need to install additional software.

Since 2021, Audacity (for Windows and Mac) has a built-in LAME MP3 encoder, so Audacity can now be used as an MP3 extractor, but it still cannot extract MP3 directly from MP4. You need to install the FFmpeg library, which helps Audacity import more formats, including MP4.

Now, follow the steps below to finish the conversion in Audacity.

Step-by-step: Convert MP4 to MP3 using Audacity

Step 1. Download the latest version of Audacity and install it on your PC. Then launch it.

Step 2. Click Edit > Preferences.

Open Preferences
Open Preferences

Step 3. Select Libraries. If it doesn’t detect ffmpeg.exe, it will display "FFmpeg library not found". Just click Download.

Step 4. Now you’ll be taken to an Audacity FAQ webpage, click Installing FFmpeg and follow the instructions on the screen to download FFmpeg to your PC.

Or, you can directly open this link https://lame.buanzo.org/ffmpeg.php to download the FFmpeg installer.

💡 For most PCs, 64-bit is the correct version.

Step 5. Click on the downloaded FFmpeg file and complete the installation. Pay attention to the destination location. By default, FFmpeg for Audacity will be stored in C:\Program Files\FFmpeg for Audacity.

💡 You can open Parameter settings and adjust the audio bitrate, channel, sample rate, and volume as you see fit. If you want to preserve good audio quality, choosing 192kbps or 256kbps as the audio bitrate is recommended. 320kbps is the highest audio quality for MP3.
