The software also supports a wide range of file formats for both import and export, including WAV, MP3, AIFF, FLAC, and many others. This flexibility ensures compatibility with virtually any audio system or platform where you might want to use your recordings.
Before diving into recording, you'll need to properly configure Audacity to capture your computer's audio output. The setup process varies slightly depending on your operating system, but the core principles remain the same.
First, download the latest version of Audacity from the official website (audacityteam.org) to ensure you have access to all current features and security updates. The installation process is straightforward—simply follow the on-screen prompts after launching the installer. For Windows users, you might need to install the optional LAME MP3 encoder if you plan to export your recordings as MP3 files.
After installation, launch Audacity and take a moment to familiarize yourself with the interface. The main window displays your audio waveforms, while the top toolbar contains recording controls and editing tools. The menu bar provides access to more advanced features and settings that you'll explore as you become more comfortable with the software.
Properly configuring Audacity to capture your PC's audio output is crucial for successful recording. The specific steps depend on your operating system, but the general approach remains consistent across platforms.
For Windows users, the WASAPI loopback feature provides the most direct method for capturing system audio. Navigate to Edit > Preferences > Devices and select "Windows WASAPI" as your audio host. Then, choose your primary output device (usually speakers or headphones) with "(loopback)" appended to it from the Recording Device dropdown menu. This configuration tells Audacity to record whatever audio is playing through your selected output device.
Mac users face a slightly different process since macOS doesn't natively support audio loopback. You'll need to install additional software like Soundflower or BlackHole to create a virtual audio device that can capture system audio. After installing one of these tools, you'll select it as both your system output in macOS sound settings and as your recording device in Audacity.
Before starting any important recording, perform a quick test to verify your settings:
Once you've mastered the basics, implementing advanced techniques will significantly improve your recordings. These methods help you capture cleaner audio and avoid common problems that plague amateur recordings.
Setting appropriate recording levels is perhaps the most critical factor in achieving professional-quality audio. Aim for peak levels between -12dB and -6dB on Audacity's meter to provide adequate headroom while maintaining a strong signal-to-noise ratio. If your levels are consistently too high (approaching 0dB), you risk distortion and clipping that can't be fixed later. Conversely, recording at too low a level introduces noise when you later amplify the signal.
Consider using Audacity's Timer Record feature for capturing scheduled audio events. This function allows you to set specific start and end times for recording, which is perfect for recording webinars, radio shows, or other timed content when you can't be present to manually control the recording process.
Recording high-quality audio requires significant system resources, so optimizing your computer's performance can prevent issues like dropouts or crashes during critical recording sessions.
Before starting an important recording, take these preparatory steps to ensure smooth operation:
For longer recording sessions, monitor your computer's performance periodically. Watch for signs of thermal throttling (computer becoming hot and slowing down) or memory issues that might affect recording quality. Consider breaking very long recordings into manageable segments if you're concerned about system stability.
Capturing audio is just the first step—editing transforms your raw recording into a polished final product. Audacity offers numerous tools to clean up and enhance your audio after recording.
Start by trimming unnecessary sections from the beginning and end of your recording. Use the selection tool to highlight unwanted portions, then press Delete to remove them. For more precise editing, zoom in on the waveform using Ctrl+1 (or Cmd+1 on Mac) to make detailed selections. The Envelope Tool allows you to adjust volume levels within specific sections of your recording, which is useful for balancing inconsistent audio levels.
Noise reduction is another critical editing process that dramatically improves recording quality. Audacity's noise reduction effect works by analyzing a section of "noise only" (such as a quiet moment before the main audio begins), then intelligently removing similar sounds throughout the recording. This process effectively eliminates background hums, computer fans, and other consistent background noises.
Audacity includes several professional-grade effects that can transform amateur recordings into broadcast-quality audio. These tools help address common audio problems and enhance overall sound quality.
The Compressor effect is essential for evening out volume fluctuations in your recording. It automatically reduces the volume of louder sections while maintaining quieter parts, resulting in more consistent audio levels throughout. This is particularly useful for recordings with varying distances from the microphone or inconsistent source volumes.
For improving clarity and presence in your recordings, try these enhancement techniques:
Remember to apply effects conservatively—subtle enhancements usually produce more natural results than dramatic changes. Always save your original recording before applying effects, and consider creating a duplicate track to experiment with different processing options.
After perfecting your recording through careful editing, the final step is exporting your project in the appropriate format for its intended use. Audacity supports numerous export formats, each with specific advantages for different applications.
The export process begins by selecting File > Export or using the keyboard shortcut Ctrl+Shift+E (Cmd+Shift+E on Mac). This opens the export dialog where you'll choose your desired file format and quality settings. For most purposes, these formats work best:
When exporting as MP3, pay attention to the bit rate setting—higher values (like 192kbps or 320kbps) produce better quality but larger files, while lower values (like 64kbps or 128kbps) create smaller files with reduced audio quality. For voice recordings, 128kbps usually provides a good balance, while music typically benefits from at least 192kbps.
Different platforms have specific audio requirements for optimal playback. Understanding these requirements helps ensure your recordings sound great wherever they're shared.
For social media platforms, consider these optimization strategies:
Before finalizing your export, always preview your recording one last time to catch any issues. Check the beginning and end for abrupt starts or cuts, verify that volume levels are consistent throughout, and listen for any artifacts or problems introduced during editing.
Even experienced users occasionally encounter technical difficulties when recording PC audio. Knowing how to identify and resolve common problems will save you time and frustration.
When no audio is being recorded despite seeing movement in the recording meter, check your input device selection in Audacity's preferences. Ensure you've selected the correct loopback device that corresponds to your active output. On Windows, verify that you're using WASAPI and have selected the appropriate "(loopback)" device. For Mac users, confirm that your virtual audio routing software (like Soundflower) is properly installed and selected in both system preferences and Audacity.
Audio distortion presents another common challenge, typically manifesting as crackling, popping, or warped sound. This usually occurs when recording levels are set too high, causing digital clipping. To fix this issue:
Sometimes conflicts between Audacity and other software can cause recording problems or performance issues. Identifying and resolving these conflicts is essential for reliable recording.
If Audacity crashes during recording or exhibits unstable behavior, try these solutions:
For persistent issues with specific applications, try recording in shorter segments rather than extended sessions. This approach reduces the chance of crashes during critical recordings and makes file management more manageable.
As you become more comfortable with Audacity's basic functions, exploring advanced features will help you achieve even better results and work more efficiently.
Keyboard shortcuts dramatically increase your editing speed once mastered. Learning common commands like Space (play/pause), Ctrl+Z (undo), and Shift+A (zoom to selection) will make your workflow significantly faster. Audacity's official documentation includes a complete list of shortcuts worth studying.
Consider creating custom presets for frequently used effect chains. If you regularly apply the same sequence of effects to your recordings (such as noise reduction, compression, and EQ), you can save these as a chain in Effects > Edit Chains. This allows you to apply multiple effects with a single command, ensuring consistent processing across all your projects.
While Audacity offers impressive capabilities on its own, integrating additional tools can further enhance your audio production workflow. These complementary resources expand what's possible with your recordings.
For more advanced audio processing, consider these additional resources:
Learning basic audio engineering principles will also improve your results.

Numerous free online resources and tutorials can help you build this knowledge base.
Audacity's versatility makes it suitable for a wide range of recording projects, each with unique requirements and best practices. Understanding these specific applications helps you tailor your approach for optimal results.
For podcast production, focus on achieving consistent voice levels and clarity. Use the Compressor effect to even out volume fluctuations, and apply EQ to enhance vocal presence. The Noise Reduction tool is particularly valuable for removing air conditioning hums or computer fan noise that often plague podcast recordings. Consider recording each speaker on a separate track if possible, which provides more flexibility during editing.
When recording music from streaming services or other online sources, timing is crucial. Start your recording before the music begins and trim the excess later to avoid missing the beginning. Be aware of copyright restrictions when recording commercial music—generally, these recordings should be for personal use only unless you have appropriate licenses.
With remote work and virtual meetings now commonplace, recording important online discussions has become essential. Audacity excels at capturing these conversations with clarity.
For optimal results when recording video conferences:
After recording, use Audacity's editing tools to remove unnecessary sections, enhance clarity, and balance volume levels between different speakers. The Noise Reduction effect can help eliminate background noise from participants in less-than-ideal environments.
As technology evolves, staying current with audio recording best practices ensures your workflow remains efficient and your results professional. Adopting forward-thinking approaches now will save you time and frustration later.
Establish a consistent file organization system for your recordings. Create a logical folder structure with clear naming conventions that help you quickly locate specific recordings months or years later. Consider including the date, project name, and version number in filenames. Maintain separate folders for raw recordings, edited files, and final exports to prevent confusion.
Implement a reliable backup strategy to protect your audio work. Follow the 3-2-1 backup rule: maintain three copies of important files, store them on at least two different types of media, and keep one copy off-site or in cloud storage. Automated backup solutions can ensure this happens consistently without requiring manual intervention.
Audacity continues to evolve with regular updates that add new features and fix bugs. Staying current with these developments helps you take advantage of improvements while avoiding potential compatibility issues.
