More and more live contents are available online — Lectures, industry forums, performances, and even concerts can be online. It is frustrating when you want to watch a live program but you are busy at that time. Or sometimes a show is so amazing that you want to keep it for playback. Thus, recording computer screens, including internal audio and video, can be very important.

However, as a Mac user, you may already know that Mac's built-in sound recorder only records sounds from your microphone. In other words, Macs actually do not allow you to record its system sound.

The good news is that you can still record internal audio with third-party software or plug-ins for Mac. Today, we will introduce you to some of the best sound recorders on Mac — which are convenient to install, and easy to operate. Among all, FonePaw Audio Recorder will be our NO.1 recommendation for you.

QuickTime: Built-in Screen Recorder on Mac, Record Internal Audio with Soundflower Plug-in

Mac users often record screens and external audio via QuickTime Player, the built-in macOS audio recorder software. However, you cannot record the internal audio directly with QuickTime. Of course, you can open the speaker so the audio can be recorded through the external microphone. But the recording environment cannot always be quiet, so sometimes other noises will be recorded. A good solution would be downloading an additional plug-in like Soundflower or Blackhole to help QuickTime record internal audio.
