Stereo Mix is a hidden feature in Windows 10 that needs to be enabled manually.

  1. Open “Input devices” in Windows 10 settings
     

    The fastest way to see available “Input devices” in Windows 10 is by searching and opening “Manage sound devices”.
     
    Windows 10 - Search - Manage sound devices

  2. Enable Stereo Mix in “Managed sound devices”

    In “Manage sound devices” you will find a disabled “Stereo Mix” entry in “Input devices”. Just click on “Stereo Mix” to show the “Enable”-button. Then you can enable “Stereo Mix” with a simple click.
     
    Windows 10 - Settings - Manage sound devices - activate Stereo Mix

How to Enable Stereo Mix in Windows 11

The process in Windows 11 is similar but with slight differences in accessing sound settings.

  1. Access Sound Options

    Right-click the speaker icon on the taskbar and select “Sound settings“.
     
  2. Select “All sound devices”
     
    Windows 11 - Select All sound devices
  3. Scroll down to “Advanced” and click on “More sound settings”
     
    Windows 11 - Select All sound devices - Stereo Mix
  4. Click “Allow” to Enable Stereo Mix Device
     
  5. Optional: Set Stereo Mix Options
     
    You can set Stereo Mix as the “default sound device“, choose the “format/quality” via bitrate and mono instead of stereo if needed (1 channel), adjust the “Stereo Mix input volume” and enable or disable the available “Audio enhancements” available for your audio chipset.

How to Enable Stereo Mix via Control Panel in Windows 10 and Windows 11 for Advanced Options

For users who prefer the traditional Control Panel interface or if the Windows Settings approach does not reveal the Stereo Mix option, here's how you can enable Stereo Mix there. In addition to what you can choose in Windows Settings, Control Panel allows to enable “Exclusive Mode” for Stereo Mix (see below).

  1. Open Control Panel
     
    Press Windows to open search, type Control Panel and press Enter.
     
    Windows 11 - Open Control Panel

  2. Open “Hardware and Sound”
     
    Windows 11 - Control Panel - Hardware & Sound

  3. Select “Manage audio devices”
     
    Windows 11 - Control Panel - Hardware ad Sound - Manage audio devices

  4. Switch to “Recording”
     
    Windows 11 - Control Panel - Hardware ad Sound - Sound Options
  5. Right-click into the white space and select “Show Disabled Devices”
     
    Windows 11 - Control Panel - Sound Options - Recording - Show Disabled Devices
  6. Enable Stereo Mix via right-click
     
    Windows 11 - Control Panel - Sound Options - Enable Stereo Mix
  7. Optional: Open Stereo Mix Properties
     
    There you can set Stereo Mix as the “default sound device“, choose the “format/quality” via bitrate and mono instead of stereo if needed (1 channel), adjust the “Stereo Mix input volume” and enable or disable the available “Audio enhancements” available for your audio chipset.
     
    Windows 11 - Control Panel - Sound Options - Open Stereo Mix Properties
  8. Enable “Listen to this device” for Stereo Mix if desired
     
    Selecting “Listen to this device” for Stereo Mix in the sound settings allows you to hear the audio that is being channeled through the Stereo Mix in real-time. Essentially, it routes the audio being played on your system (which Stereo Mix is set to capture) directly to your speakers or headphones, enabling you to monitor exactly what Stereo Mix is recording.
     
    Windows 11 - Control Panel - Sound Options - Stereo Mix Properties - Listen
  9. Adjust Stereo Mix volume in “Levels”
     
    Windows 11 - Control Panel - Sound Options - Stereo Mix Properties - Levels
  10. Choose other audio device settings in “Advanced”

    In addition to what you can choose in Windows Settings, Control Panel allows to enable “Exclusive Mode” for Stereo Mix:

    Allow applications to take exclusive control of this device: When this option is enabled, applications can request exclusive access to Stereo Mix. This means an application can take over the device and change its settings (like format and levels) without considering other applications' needs. This can be useful for recording or streaming software that requires specific audio settings to function correctly. However, it might also lead to conflicts if multiple applications try to access the device simultaneously or if you want to use the device for more than one application at a time.
     
    Give exclusive mode applications priority: This option works in conjunction with the first one. When both are enabled, applications that request exclusive control while another application is using Stereo Mix in shared mode can force the current application to release control. This ensures that high-priority applications (like professional recording software) can always access the device with the settings they need, even if another application is already using it.
     

B) Enabling Stereo Mix

  1. Go to the Recording Tab: In the Sound dialog, switch to the “Recording” tab to see a list of available recording devices.

  2. Reveal Hidden Devices: Right-click in an empty area within the tab and select “Show Disabled Devices”. This action should make the Stereo Mix option visible if it was hidden.

  3. Enable Stereo Mix: Find “Stereo Mix” in the list, right-click on it, and choose “Enable”. You might also want to set it as the default device by right-clicking on it again and selecting “Set as Default Device”.

How to Record Windows System Audio using Stereo Mix in Audio Apps like Audacity

With Stereo Mix enabled on your Windows 10 or Windows 11 system, you can capture system audio directly through Audacity, a widely-used, free audio recording and editing software, or any other audio recording app. Here, we use Audacity as an example, but you can use this method in other recording software with slight variations.

Setting “Stereo Mix” as the Input Device in Audacity

  1. Open Audacity
     
    Launch Audacity. If it's not installed, download it from the official website. Ensure you have the latest version for optimal compatibility with Windows 10 or Windows 11.

  2. Select Stereo Mix
     
    Find the microphone icon in the upper toolbar of Audacity. Click the dropdown menu next to it and choose “Stereo Mix” from the list. This action directs Audacity to use your system's audio output as the recording source, instead of an external microphone.

  3. Adjust Recording Levels
     
    Play the audio you wish to record and observe Audacity's level meters. Use the recording level slider, located next to the microphone icon, to adjust the input volume. Aim for a level that avoids distortion but is loud enough to capture clearly.

  4. Start Recording
     
    Press the red “Record” button in Audacity to begin recording the audio playing on your system. Everything you hear through your speakers or headphones will be recorded.

  5. Stop and Save
     
    Click the yellow “Stop” button when you're done. Audacity allows you to edit the audio if necessary. To save your work, navigate to “File” > “Export” and select your preferred audio format.

Additional Tips for Using Stereo Mix with Other Recording Software

  • The process of selecting “Stereo Mix” as the recording source should be similar in most audio recording applications. Look for an option to choose the input device or source and select “Stereo Mix” from there.
  • If “Stereo Mix” does not appear as an option in your recording software, revisit your sound settings to ensure it's enabled and set as the default device.
  • Regularly update your recording software to maintain compatibility with your operating system and to access the latest features and fixes.
