How to Export Audacity File to MP3: The 3 Easy Steps

If exporting Audacity files to MP3 seems daunting, dont worry! You can do it with just 3 steps. Read on! 

Step 1: Install the LAME MP3 Encoder

To export audio files to the MP3 format in Audacity, you will need to install the LAME MP3 encoder. Here’s a step-by-step guide on how to do it:

Download the LAME MP3 encoder:

First, visit the LAME website and download the appropriate encoder version for your operating system. Make sure to choose the correct version (32-bit or 64-bit) based on your system.

Locate the downloaded file:

Once the download is complete, go to your computer’s Downloads folder or where your browser saves downloaded files. Look for the file named “lame_enc.dll” (for Windows) or “lame.framework” (for Mac).

Copy the file:

Next, copy the downloaded file. In Windows, right-click on the file and select “Copy” from the context menu. In Mac, right-click on the file and select “Duplicate” to create a copy.

Navigate to the Audacity installation folder:

Open a new File Explorer (Windows) or Finder (Mac) window and navigate to the folder where Audacity is installed. The default installation path on Windows is “C:\Program Files (x86)\Audacity,” and on Mac is “/Applications/Audacity.”

Paste the file:

Go to the “Plug-Ins” directory once in the Audacity installation folder. Right-click inside the directory and select “Paste” (Windows) or “Paste Item” (Mac) to copy the LAME MP3 encoder file into the appropriate location.

Restart Audacity:

After pasting the file, close and reopen Audacity to ensure that the LAME MP3 encoder is recognized and available.

That’s it! You have successfully installed the LAME MP3 encoder in Audacity. Now you can export your audio files to the MP3 format with ease. Keep in mind that the LAME MP3 encoder is a third-party software, so make sure to download it from a reputable source.

Step 2: Exporting the File to MP3

Now, let’s move on to exporting your file to MP3. Follow the step-by-step guide below:

  1. Locate the Downloaded File: Once the download is complete, locate the LAME MP3 encoder file on your computer. Unless you specify a different location, it’s typically saved in your system’s default downloads folder.
  2. Copy the file: Right-click on the LAME MP3 encoder file and select “Copy” from the drop-down menu.
  3. Navigate to the Audacity installation folder: Depending on your operating system, the folder can be found in different locations. For Windows, you can find it in C:\Program Files (x86)\Audacity. For macOS, look it in /Applications/ And for Linux, find the file /opt/Audacity.
  4. Open the file: Open File Explorer (Windows) or Finder (macOS) and navigate to the Audacity installation folder.
  5. Paste the file in the appropriate location: Find the “Plug-Ins” or “Effects” folder in the Audacity installation folder and open it. Right-click inside the folder and select “Paste” to copy the LAME MP3 encoder file into this location.
  6. Restart Audacity: Close Audacity if it is running, then reopen the program. This step ensures that Audacity recognizes the newly added LAME MP3 encoder and makes it available for exporting to MP3.

Step 3: Adjusting the MP3 Export Settings

When exporting audio files to MP3 format in Audacity, it is important to customize the export settings according to your preferences and requirements. Audacity provides a range of options that allow you to fine-tune the quality and file size of your MP3 files. Let me guide you through adjusting the MP3 export settings in Audacity.

  1. Launch Audacity and open the audio file you want to export as an MP3.
  2. Go to the “File” menu and click “Export” to open the export settings window.
  3. In the export settings window, locate the “Save as type” or “Format” dropdown menu. Choose “MP3” as the desired format.
  4. Next, you will see an ” Options ” section or “Settings.” Click on it to expand the options available for MP3 export.
  5. One of the most important settings to consider is the Bit Rate Mode. This determines the trade-off between file size and audio quality.
  6. Depending on the selected bit rate mode, you may have additional settings to tweak. These may include Bit Rate, Quality, or Target File Size options. Adjust these settings according to your needs.
  7. Once you have finalized the export settings, choose the location on your computer where you want to save the MP3 file and click the “Save” button.

For bitrate mode, you can choose from these:

  • Constant Bit Rate (CBR): Maintains a consistent bit rate throughout the entire audio file. This option is suitable if you prioritize a specific bit rate or file size.
  • Variable Bit Rate (VBR): Adjusts the bit rate dynamically based on the complexity of the audio, resulting in better audio quality with smaller file sizes. This option is recommended if you want to balance both quality and file size.
  • Average Bit Rate (ABR): Sets an average bit rate, which allows for variations above and below the specified rate. ABR is a good choice if you want to maintain a certain level of quality while keeping the file size in check.

That’s it! With these steps, you can now adjust the MP3 export settings in Audacity to create high-quality, efficiently sized MP3 files. Remember to experiment with different settings to find the perfect balance between audio quality and file size.

Excessively Large File Size Post-ExportExported MP3 files with unusually large sizes often result from high bit rate settings or complex audio content.
 Adjust the bit rate downwards or opt for a lower quality setting for your MP3 export.
Decreased Audio Quality in Exported MP3This may occur if the bit rate is too low or if the original file has undergone significant compression.
Increase the bit rate or select a higher quality setting for your MP3 export.
Synchronization Issues in Multi-Track ProjectsThis usually happens if tracks are misaligned or if there’s a mismatch in audio settings across tracks.
Carefully check the alignment of your tracks and ensure consistent audio settings for each one.


How can I reduce the size of my MP3 file when exporting from Audacity?

You can reduce the size by choosing a lower bit rate during the export process, which may also reduce the audio quality.

Can I export files from Audacity to formats other than MP3?

Absolutely. Audacity supports various formats, including WAV, AIFF, OGG, and FLAC. You can choose your preferred format in the export dialogue box.

Will exporting my file to MP3 change the quality of the audio?

MP3 is a lossy format, which means there might be some quality loss during the export, especially if a low bit rate is chosen. For minimal quality loss, choose a higher bit rate.

What is the best bit rate to choose when exporting to MP3?

A bit rate of 192 kbps or higher is recommended for a balance of quality and file size. However, for professional quality, you might prefer 320 kbps.
