If you need to make a recording of audio that is playing on your Mac, you might prefer to use the free Audacity application. For example, you are streaming a public domain audio or video file from the Internet Archiv, and you want to capture a recording of it for your research, or you have a video that you shot with Apple's native video recording application Photo Booth and you want to make a recording of its audio. You need the free Soundflower plugin on your Mac before recording internal audio with Audacity.

Skill level:


  1. 1

    Launch your Web browser. Go to the Cycling 74 website (, click "Products" and then click "Soundflower." Download the free Soundflower plugin to your Mac. Double-click the Soundflower DMG disc image file to expand it and reveal the Soundflower package file. Double-click the "Soundflower.pkg" file to install the Soundflower plugin.

  2. 2

    Click the Apple logo at the top left of the Mac, and then click "System Preferences."

  3. 3

    Click "Sound," and then click the "Output" tab.

  4. 4

    Click "Soundflower (2ch)." This diverts audio from your Mac's speakers to the Soundflower module, from which Audacity can record.

  5. 5

    Click "Applications" on the Dock of your Mac, and then click "Audacity" to launch the application. A new empty recording window appears.

  6. 6

    Click the "Built-in Input" pull-down menu at the top of the Audacity window, and then click "Soundflower (2ch)."

  7. 7

    Play the audio on your Mac that you want to record. For example, click the "Play" button on a streaming video or audio file, or in the window of Photo Booth.

  8. 8

    Click the red "Record" button at the top of the Audacity window. The waveform of the audio appears in the window as it records.

  9. 9

    Click the yellow "Stop" button to stop recording.

  10. 10

    Click "File" from the Audacity menu, and then click "Save Project." A dialogue box appears. Type a name for the recording in the "Save As" box, then click a folder on your Mac where you want to save the file, and then click "Save."
