Recording the sound playing on your Mac.
To record the "system audio" playing on your Mac, Screenflick 2 uses an audio extension called Screenflick Loopback. It must be installed before Record System Audio will work.
It's an audio extension that lets Screenflick 2 record the sound playing on your Mac. It adds a "virtual" audio device that Screenflick records from. Keep reading.
Click the "Audio Extension…" button next to "Record System Audio" in Screenflick, and then click "Install" or "Uninstall". Keep reading.
Screenflick Loopback creates a "virtual" audio device with input and output streams. When a recording with system audio starts, Screenflick makes it the system-wide default audio output device, which directs everything your Mac plays into Loopback's input. Screenflick then records from Loopback's output. When the recording ends, your speakers are selected again.
See Troubleshooting System Audio if an application's audio is missing from a recording.
Click the Audio Extension… button in Screenflick, and then click the Uninstall button in the sheet that opens.
Alternatively, delete the file /Library/Audio/Plug-Ins/HAL/ScreenflickLoopback.driver and restart your Mac.
