This approach maintains digital audio quality throughout the recording process.
Download and install BlackHole from the developer's GitHub repository by following their installation instructions. The installation process creates a virtual audio device that appears in your macOS audio settings alongside physical devices. This virtual device serves as a bridge between your system audio and Audacity.
After installation, open Audio MIDI Setup from your Applications > Utilities folder. Click the plus icon in the lower left corner and select "Create Multi-Output Device" to create a new virtual device. Check both your regular output device (like Built-in Output) and BlackHole 2ch in the device list to route audio to both simultaneously.
Configure your system to use this new Multi-Output Device by selecting it as your sound output in System Preferences > Sound > Output. This configuration sends all system audio both to your speakers/headphones and to the BlackHole virtual device. Open Audacity and select BlackHole 2ch as your recording device to capture this routed audio.
Key considerations when using virtual audio drivers include:
Physical audio routing provides an alternative for Mac users who prefer hardware solutions or encounter issues with virtual drivers. This approach uses a loopback cable connecting your Mac's headphone output to its microphone input, creating a physical audio path. Standard 3.5mm audio cables with appropriate connectors work well for this purpose.
Connect one end of your audio cable to your Mac's headphone jack and the other end to the microphone input. This physical connection routes your computer's audio output back into its input for recording. Open System Preferences > Sound and select "Line In" or "External Microphone" as your input device to enable this audio path.
Launch Audacity and select the appropriate input device corresponding to your physical connection. This selection typically appears as "Built-in Input" or similar in the recording device dropdown. Test the connection by playing audio on your Mac and observing the recording meter in Audacity to verify proper signal flow.
Linux systems offer flexible audio recording options through the PulseAudio sound server, which manages audio routing between applications and hardware. This architecture allows for sophisticated audio capture configurations without additional software in most cases. PulseAudio comes pre-installed on most modern Linux distributions, providing a solid foundation for computer audio recording.
The key to successful Linux recording lies in proper configuration of audio routing within PulseAudio. This process typically involves using PulseAudio Volume Control (pavucontrol) to direct audio from playback applications to Audacity's recording input. The graphical interface makes complex audio routing accessible even to users without technical audio knowledge.
Linux recording setups benefit from the operating system's modular design, allowing for customized audio workflows. Advanced users can create persistent audio routing configurations that automatically enable recording paths at startup. This flexibility makes Linux particularly valuable for automated recording scenarios or specialized audio workflows.
Install PulseAudio Volume Control if not already present on your system using your distribution's package manager. Common installation commands include "sudo apt install pavucontrol" for Debian/Ubuntu systems or "sudo dnf install pavucontrol" for Fedora-based distributions. This utility provides the graphical interface needed to configure audio routing.
Launch Audacity and select "ALSA" or "PulseAudio" as your audio host depending on your system configuration. Choose "pulse" as your recording device if available, or select the default system input device. Start a recording session in Audacity but don't worry if no audio appears yet-we'll configure the routing in the next step.
Open PulseAudio Volume Control while Audacity is recording and navigate to the "Recording" tab. Look for Audacity in the application list and use the dropdown menu to change its input from the default microphone to "Monitor of [your output device]." This selection tells PulseAudio to route your system's audio output to Audacity's recording input.
Audio recording problems often stem from incorrect device selection or configuration issues. When no audio appears in your recording, first verify that you've selected the correct recording device in Audacity. Windows users should ensure WASAPI loopback targets the active output device, while Mac users need to confirm proper virtual driver routing.
Signal level problems manifest as either too-quiet recordings or distorted audio from excessive volume. Monitor the recording meter in Audacity during setup to ensure proper levels-ideally, the peak signal should reach about -6dB for optimal quality without clipping. Adjust system volume or recording sensitivity as needed to achieve appropriate signal strength.
Software conflicts sometimes interfere with audio recording, particularly when multiple applications attempt to access the same audio devices. Close unnecessary audio applications before recording to prevent resource contention. Some audio drivers also limit simultaneous access to devices, requiring exclusive access for proper recording functionality.
Verify active audio playback when using WASAPI loopback or similar methods that only capture live audio streams. Some recording methods pause or create silent recordings when no audio plays through the selected device. Play a continuous audio source during testing to ensure consistent signal detection.
Check for muted channels or incorrect routing in your system's audio mixer. Windows users should examine Volume Mixer settings by right-clicking the speaker icon, while Mac users should verify audio routing in Audio MIDI Setup. Linux users can inspect routing configurations in PulseAudio Volume Control to identify potential signal path issues.
Eliminate unwanted background sounds by temporarily disabling system notifications and alerts during recording sessions. These sounds often appear in recordings unexpectedly, particularly when using methods that capture all system audio. Consider creating a dedicated recording profile in your operating system with notifications disabled for cleaner recordings.
