Convert MP4 to MP3 with Audacity – Windows

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

Step 2. Click Edit > 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.

Step 6. Restart Audacity. Click Edit > Preferences > Libraries again to check if the ffmpeg.exe is detected. If you have installed FFmpeg elsewhere, you will need to click the Locate button and find the FFmpeg folder manually.

Step 7. Now, click File > Open to import an MP4 file. You can also drag and drop the file into its interface. (Edit the audio track if needed)

Step 8. Click File > Export Audio (> Export to Computer).

Step 9. In the Export Audio window, click Browse to set a destination folder. Then select MP3 Files from the Format drop-down menu.

You can modify the audio options as desired or leave them as default. Finally, click Export to extract the MP4 audio as MP3.

Step 1. Launch WonderFox Free HD Video Converter Factory on your PC and open the Converter program. Next, click Add Files to import the MP4 files into the conversion list.

Step 2. Click the output format on the right side of the program. Then, head to the Audio format section and select MP3 as the output format.

💡 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.

Step 3. Finally, set an output folder by clicking the bottom ▼ button and then press Run to start the conversion immediately.

💡 Before conversion, you can also trim or merge the files.
