Exporting audio from GarageBand allows you to save your projects as universally playable sound files, making them shareable and ready for other applications or devices. This process converts your multi-track project into a single, cohesive audio file.
Exporting Your GarageBand Project to an Audio File
The primary method to export your GarageBand song as an audio file involves using the Share menu. This will save your entire project, or a selected portion, as a stereo audio file.
Step-by-Step Guide to Exporting
- Open Your Project: Launch GarageBand and open the project you wish to export.
- Access the Share Menu: In the top menu bar, click on Share.
- Select Export Option: From the dropdown menu, choose Export Song to Disk....
- Configure Export Settings:
- Name Your Song: Enter a descriptive name for your exported audio file.
- Choose a Destination: Select where you want to save the file on your computer. You can also save directly to a flash drive or cloud-based storage platform from this window.
- Select Your Format: This is crucial for determining file size, quality, and compatibility.
- Adjust Quality (if available): Depending on the format, you might be able to select a bit rate or quality level.
- Click Export: Once all settings are configured to your preference, click Export to save your audio file.

Understanding Audio File Formats
GarageBand offers several audio file formats, each with different characteristics regarding compression, file size, and quality. Your choice depends on your specific needs, whether it's for sharing online, archiving, or further professional use.
Common Export Formats
When you export, you'll choose from the following popular formats:
| Format | Type | Characteristics | Compatibility |
|---|---|---|---|
| AAC | Compressed | Smaller file size, good for streaming and general listening. Uses lossy compression, meaning some data is removed. | Widely compatible (Apple devices, most media players). |
| MP3 | Compressed | Very small file size, highly popular for sharing and portable devices. Uses lossy compression, similar to AAC. | Universally compatible. |
| AIFF | Uncompressed | Higher quality, larger file size. Retains all original audio data. Ideal for archiving or professional audio work. | Primarily Mac compatible. |
| WAVE (WAV) | Uncompressed | Highest quality, largest file size. Retains all original audio data. Excellent for professional use. | Mac & Windows compatible. |
Choosing the Right Format
- For general sharing, emails, or small file sizes, choose AAC or MP3. These are compressed formats, resulting in smaller files that are quick to upload and download.
- For maximum audio quality, professional mixing/mastering, or archiving, opt for AIFF or WAVE (WAV). These are uncompressed formats, preserving all the original audio data but resulting in significantly larger files. WAVE offers broader compatibility across both Mac and Windows systems.
Tips for Optimal Export Quality and Workflow
Consider these additional points to ensure your exported audio meets your expectations.
Adjusting Export Range
If you only want to export a specific section of your song, rather than the entire project, you can use the Cycle Region feature:
- Drag the yellow cycle region bar at the top of the timeline to define the start and end points of the section you wish to export.
- When you go to Share > Export Song to Disk..., ensure the "Export Cycle Area Only" (or similar phrasing) checkbox is selected if you want only that specific portion.
Mastering and Volume Levels
- Before exporting, ensure your overall project volume levels are appropriate. Avoid clipping (distortion due to excessive volume, indicated by red peaks in the level meters).
- GarageBand includes basic mastering tools. You can apply a Limiter or Compressor on the Master Track (found in the Smart Controls for the Master track) to optimize the loudness and dynamics of your song before export.
Exporting Individual Tracks (Stems)
While the main export function creates a single stereo mix, you can also export individual tracks (often called "stems") if you need to further mix them in another digital audio workstation (DAW) or share them separately.
- Mute all other tracks except the one you want to export.
- Go to Share > Export Song to Disk... and export that single track.
- Repeat for each track you need as a separate file.
Note: This process can be time-consuming for many tracks.
