Installing iShowU Audio Capture (Mojave and earlier)


What is iShowU Audio Capture?

iShowU Audio Capture is an extension to OS X used by iShowU Studio and iShowU Instant to record audio from your computer. This new-and-improved audio driver replaces Soundflower and provides a bunch of new features and improvements in order to make recording audio more stable and easy to do.

Download Installer Catalina - Go Here

iShowU Audio Capture is designed for use with iShowU Studio or iShowU Instant. You may use it for other purposes but we can only provide support for its use with iShowU products.

Features & Improvements 

  • Much more stable - When you quit the app, or even if the app* crashes, your default audio device will switch back to what it was before. This means no more weird issues where your sound seem to disappear!
  • More intelligent - Your audio output device will only be switched when it needs to and only switched back when it needs to.
  • Better volume support - When recording audio from your computer, adjusting the volume will now work seamlessly, as you'd expect it to.
  • Workspace support - When you switch to another user/workspace your audio output device will automatically switch back to how it was, and then return to capturing audio when you switch back.

* True with iShowU Instant and iShowU Studio 2 only

Installing iShowU Audio Capture on High Sierra

  1. Download the iShowU Audio Capture installer.
  2. Once the download has finished, find the installer - it will probably be in your Downloads folder.
  3. Open the installer (the .dmg file).
  4. Run the iShowU Audio Capture package by double-clicking it and following through the prompts. You will need to enter your password to complete the installation.
  5. You may be prompted to confirm the installation of the driver. This is not an error. This is completely normal. Keep following along :)
  6. Click OK on the "System Extension Blocked" dialog. That's fine. Soon you'll see:
  7. Now go to System Preferences, and click on Security & Privacy:
  8. Confirm the installation of the kext. This is really really important. Otherwise the driver will not be installed.Step5_5.png
  9. To confirm the setup is working: Open System Preferences, select Sound and then Output. There should be a new device called iShowU Audio Capture.



Installing iShowU Audio Capture (Sierra and earlier)

    Wow! iShowU worked like a charm!

    I just installed it, selected output device as iShow, ran QuickTime player with screen recording and selected iShow for sound input and boom!

    it worked so well.

    Thank you!

    This is working really well. I made a point of mentioning it in my recent blog post on the best tips for teachers when moving to an online learning model. I wanted to help music educators adjust to this period of uncertainty by giving them some tips on some of the best software out there.

    Here’s the link to my post:

    I’ve already shared it on multiple social media platforms as well as the British Columbia music educator’s Facebook groups. Check it out. :D
