Many users are looking for how to record computer audio and microphone at the same time on Windows or Mac with Audacity. Let's delve into this article for a step-by-step guide.

Audacity Record Computer Audio and Mic Simultaneously

Audacity is a free, open-source audio recorder that lets you capture system sound and microphone. It's popular among podcasters, gamers, and creators for tutorials or streaming. With multi-track recording, you can edit internal audio and voice separately, then export in MP3, WAV, or FLAC.

However, Audacity doesn't natively support recording system audio and mic at the same time, since it normally only accepts one input source. To work around this, you can adjust your Windows sound settings by enabling "Listen to this device" and using a loopback input such as WASAPI.

🚩Follow these steps to Audacity record desktop audio and mic at the same time:

Step 1. Enable the microphone's "Listen to this device" feature in Windows Sound settings.

  • Right-click the speaker icon in the system tray at the bottom-right of your screen.
  • Click Sounds (or Sound settings > More sound settings in Windows 11).

  • Go to the Recording tab, right-click the mic used to capture sound from your computer, and click Properties.

  • Go to the Listen tab, check Listen to this device, and click Apply > OK. Now, you can hear sound from the mic in real time.

Step 2. Download and install Audacity to your Windows Computer.

  • Visit its official website and choose an installer (Editor here chose the 64 bit installer).  Follow the on-screen instructions to finish the installing setup. Then, launch the app.

Step 3. Configure Audacity audio settings.

In Audio Setup:

  • Set Host to Windows WASAPI. This enables direct system audio capture.

  • Set Recording Device to Speaker (loopback). This records the internal sound your computer is playing. (When using the default MME host in Audacity, you may see a virtual input such as Stereo Mix or What U Hear. Selecting it allows you to record the sound played on your desktop.)

  • Set Playback Device to your microphone. This ensures your mic input is also included in the recording.

Step 4. Start recording system audio and mic on Audacity.

  • Click the Record button (red dot) in Audacity.
  • Speak into your microphone while playing system audio (music, videos, etc.).
  • Both the microphone and system audio should appear as a single waveform.
  • Click Stop (square) when done and playback to check the recording.

Step 5. Save the recording on your computer.

  • Go to File > Export Audio... and follow the on-screen instructions to save your Audacity recording.

 Tips for "Listen to this device":

1. Use headphones to avoid echo or feedback.

2. Make sure you enable the correct microphone.

3. Turn it off when not recording to prevent unwanted playback.

4. Adjust the microphone volume to avoid distortion.

5. Some USB or laptop mics may not support this feature. Update drivers if needed.

How to Record Microphone and Computer Audio on Windows Perfectly

Unlike Audacity's "Listen to this device" method, which may cause echo or latency when monitoring through headphones, EaseUS RecExperts offers a smoother solution for recording both system audio and microphone simultaneously. There's no complicated Windows setup or risk of feedback, making it beginner-friendly.

With this internal audio recorder for Windows or Mac, you can easily capture internal sound, mic input, and system audio on separate tracks or a single track.

⭐Some audio recording features:

  • Record internal system audio and microphone input together or separately.
  • Adjust the balance between system and microphone audio in real time.
  • Noise cancellation, microphone boost, and more functions help you gain control for better quality.
  • Save audio from YouTube, Netflix, and more in MP3, AAC, WAV, and other formats for editing and sharing.

How to Record Computer Audio on Mac with Audacity

The way to use Audacity to record system and mic sound on Mac is different from that of Windows: it is even harder. Mac doesn't natively allow apps to record system audio, so Audacity can't capture internal sound directly.

To work around this, you need a free virtual audio driver like BlackHole screen recording or Soundflower, which routes Mac audio into Audacity. Setting this up can be tricky for beginners, but once configured, it enables simultaneous recording of computer audio and mic.

🚩Here is how to record computer audio with Audacity Mac:

Step 1. Download and install the Mac version of Audacity from audacityteam.org. Drag it into your Applications folder.

Step 2. Install an audio loopback driver such as BlackHole or Soundflower. Here we take BlackHole as an example.

Step 3. Open Audio MIDI Setup and create a Multi-Output Device (e.g., Built-in Output + BlackHole) for system sound capture.

Step 4. For microphone input, create an Aggregate Device (Built-in Microphone + BlackHole).

Step 5. Go to System Settings > Sound > Output and set the Multi-Output Device as your output.

Step 6. In Audacity, set Host to Core Audio, Recording Device to BlackHole 2ch, and Playback Device to BlackHole 2ch.

Step 7. Play your audio and click the Record button in Audacity.

Step 8. Press Stop when finished, then edit and export the file in your desired format.

How to Record System Audio and Microphone at the Same Time Android

To record system audio and microphone simultaneously on Android, we recommend you use the built-in screen recording function. It allows you to record the screen of your smartphone without time limits. Besides, recording audio and microphones can also be achieved with this tool.

🚩Steps for how to record internal audio and mic in Android

Step 1. Swipe down the function tab on the top of your screen and find a tile labeled Screen recorder sitting on the second page.

Step 2. Long-press it to go to the setting tab and select System audio and microphone sound as the sound settings.

Step 3. Tap the Start recording button to record audio and mic at the same time.

Tip: Most modern Android phones (Android 10+) have a built-in recorder with system audio support, including Samsung, Google Pixel, OnePlus, Xiaomi, Realme, OPPO/Vivo, and Huawei. If your Android device lacks the feature, try a third-party Android screen recorder instead.

Record System Audio and Microphone at the Same Time iPhone

Recording both system audio and microphone simultaneously on mobile devices is useful for gameplay, tutorials, or app reviews. On iPhone, Apple's built-in Screen Recording tool also supports recording microphone input together with system sounds.

The main challenge is that not all devices or iOS versions allow internal audio recording due to privacy restrictions. On iPhone, system audio can only be captured from apps that permit it. To bypass these limits, users often rely on third-party screen recording apps or external audio mixers. Choosing the right tool ensures you capture both audio sources clearly without missing sound.

Conclusion

Recording system audio and microphone together can feel tricky since Audacity and mobile devices don't natively support it. But with the right setup—whether using Stereo Mix, WASAPI loopback, BlackHole on Mac, or screen recorder apps on Android/iPhone - you can capture both sources smoothly.

For those who want an easier option without complex settings, tools like EaseUS RecExperts provide a one-click solution. Choose the method that best fits your device and workflow to create clear, professional-quality recordings.
