Can I still use QuickTime Player to record the internal sound on Mac?

QuickTime Player is helpful to record the internal sound on your Mac computer with the help of Soundflower – an audio extension that is massively used in Mac computers for audio recording.

How Soundflower works?

QuickTime cannot record the internal sound due to the absence of a recordable audio output device.

With QuickTime installed, users can use it to manually create a virtual audio output device on a Mac computer for internal audio playback. Then, QuickTime can detect this new device and record the sound from it.

In this way, you can use QuickTime to record the internal sound on your Mac.

Should you use QuickTime along with Soundflower to record internal sound?

From my point of view, to set up Soundflower is not an easy task. You need to locate a lot of items and tick several options. If you miss one or make just one mistake, QuickTime cannot record the internal sound relatively.

Also, QuickTime has quite a few limitations.

Cons of QuickTime audio recording:

  • You cannot change the format of the audio file (m4a. only) and trim the audio.
  • There’s no shortcut for activating QuickTime audio recording. So when you’re about to record the sound from an online interview or meeting, it could be messed up to ask other participants to wait for a while.
  • QuickTime can only record one audio source at a time. So when you’re about to record a meeting or interview, you can only choose to record your own voice or others’ voices.

Now, you might wonder how to record internal audio on Mac without Soundflower and QuickTime. You can try Aiseesoft Mac Screen Recorder.
