1. Screen Recording On Mac Has No Sound Effect

If you have ever tried recording your Mac’s screen, you probably know that QuickTime is the best way to do it. It supports recording entire screens, selective regions, and even allows you to record voice overs at the same time, using your Mac’s built-in microphones. Record your computer's screen with audio on a Mac. You can use QuickTime Player along with a free piece of software to record both video and audio from your Mac OS X machine. When saving your recording automatically, your Mac uses the name ”Screen Recording date at time.mov”. To cancel making a recording, press the Esc key before clicking to record. You can open screen recordings with QuickTime Player, iMovie, and other apps that can edit or view videos. Some apps might not let you record their windows. How to Record Screen on Mac ( macOS Catalina & macOS Mojave) Luckily it’s easy to record what is happening on the screen of your Mac as I said earlier that macOS Catalina and macOS Mojave has a built-in screen recording feature and there’s no need to install any other screen recording applications.

1. Install loopback audio (free extension).
2. Open the media you want to screen capture in your application (if it’s a browser, use Firefox or Chrome, not Safari). Start at least 5 seconds before where you want to start – this will usually give time for the application to hide any playback controls which might be distracting. Don’t press play yet.
3. Go to System Preferences/Sound. In the sound Output, choose Loopback Audio in the Output tab.
   At this point, you will hear no sound from any of your Mac’s applications, but don’t worry.
4. Go to the QuickTime Player application; choose File/New Screen Recording.
   
5. Choose if you want to record all your screen, or a portion of your screen (highlighted in red below), then click on the Record button.
   
   
6. Click on the Options menu.
   Choose the appropriate audio source, in this case Loopback Audio.
   
   
7. Go to the application that was set to play the video; press play (hopefully you queued up the video to play at least 5 seconds before the area you wanted to capture – this will usually give time for the application to hide any playback controls which might be distracting).

After you’re done recording:

2. At the top of your screen (to the right of Finder menu items), click on the black square, which is the button to stop the Quicktime recording.
   Save your video file.
3. Go to System Preferences/Sound. In the sound Output, change the preference back to Internal Speakers (or whatever was your original choice). You should be able to hear sounds now from your speakers.
4. Go to your saved movie in QuickTime Player, and test out the sound. Trim the clip either in QuickTime Player or iMovie.
