For capturing system audio with more advanced capabilities, software options like Audacity and OBS Studio stand out due to their flexibility, advanced features, and broad user base. Audacity is a powerful, open-source audio editor and recorder that’s excellent for both simple recordings and complex audio editing tasks. OBS Studio, primarily known for streaming and video recording, also offers robust options for capturing high-quality system audio alongside video.

Audio Recording with Audacity from Windows

1. Download and Install Audacity: First, ensure you have Audacity installed. It’s freely available for download from the official Audacity website for Windows, macOS, and Linux platforms.

2. Configure Recording Device: In Audacity, go to Edit > Preferences > Devices. Under the Recording section, select your system’s sound device or stereo mix as the recording device. If “stereo mix” is not available, you may need to enable it in your sound card settings or update your audio drivers.

3. Select the Recording Channels: Still in the Devices tab, ensure you’ve selected “2 (Stereo) Recording Channels” if you’re aiming to capture stereo system audio.

4. Adjust Quality Settings: Navigate to the Quality tab within Preferences. Here, you can set your desired sample rate and bit depth. For most purposes, a sample rate of 44100 Hz and a 24-bit depth should suffice.

5. Start Recording: Close the Preferences window and hit the red button in Audacity. This will start capturing all audio played through your system.

  1. Pick out the display input you’d like to use, especially if you plan to include the video. By default, OBS Studio captures both your screen visuals and the desktop audio concurrently. Should you wish to record solely the audio, it’s necessary to toggle off the video capture feature. This can be done by clicking on the eye icon located next to the source you’ve added, thereby deactivating the video stream capture while still recording the audio.

  1. To manage audio settings, head to ‘File’ located at the top-left corner of the screen.

  1. Click on ‘Settings’ within the dropdown list.

This is also the point where you can tweak the quality of the audio as per your requirements.

  1. Click ‘OK’ once you’ve adjusted your audio settings as needed.

  1. Run a trial to make sure OBS is capturing both video and audio accurately. If it’s functioning correctly, proceed to record the audio you require. When done, halt the recording and save the captured material.

Following the instructions, you will acquire a video file, typically in MKV format, that includes your audio. OBS Studio is unable to extract and save audio files independently; they are embedded in the video file. However, if you need just the audio portion, there’s no need to worry. You can use conversion tools to get an audio. 

Method 3: Recording With Online Audio Recording Tools And Browser Extension 

1. An Online Audio Recorder (e.g., Apowersoft Free Online Audio Recorder):

This type of recorder runs in your web browser and often requires you to install a small launcher application the first time you use it.

Steps to Use:

  1. Visit the tool’s website.
  2. Press the ‘Start Recording’ button, which might prompt you to download and install a launcher.
  3. Choose the audio source (system sound, microphone, or both).
  4. Click the ‘Record’ button to start capturing the audio stream.
  5. Stop the recording when finished, and you can then save the audio file to your device.

2. Browser Extensions for Audio Recording (e.g., Chrome Audio Capture):

Browser extensions integrate directly into your web browser, allowing you to record audio from any tab.

Steps to Use:

  1. Add the extension to your browser from the browser’s extension or add-on store.
  2. Navigate to the webpage with the audio stream you want to record.
  3. Click on the extension icon in your browser toolbar to start recording.
  4. Capture the audio from the page; some extensions might have a time limit for recording.

  1. Click ‘Save’ on the extension to stop recording and download the file to your computer.

Common Formats For Saving Audio Files

When it comes to saving your recorded audio, there are several common formats to choose from. MP3 is one of the most widely used formats, known for its compatibility and relatively small file size. 

WAV is another popular format that offers high quality but results in larger file sizes. AAC is a newer format that provides a good balance between quality and file size, making it a popular choice for podcasts and other online audio content.

Tips for Editing and Enhancing Your Audio Recording

  1. Trim Silence or Unnecessary Parts: Removing dead air or irrelevant sections keeps your recording engaging and focused.
  2. Normalize Volume Levels: Ensuring consistent volume throughout your recording avoids fluctuations that can distract or annoy listeners.
  3. Apply Noise Reduction: Minimizing background noise helps in improving the clarity and quality of your audio.
  4. Use Compression: Balancing the dynamic range makes your recording sound more professional by ensuring loud and soft sounds are at a pleasant listening level.
  5. Edit in Good Microphone: A high-quality microphone like Hollyland Lark Max is an incredible device that allows you to catch subtle nuances and ensure your edits have the desired effect across different playback systems.
