Soundflower is a system extension that lets you channel audio from one application to another. Cycling ’74’s free Soundflower is that way. The first step involves finding a way to grab audio playing in one application-a Web browser, for example-and route it to an application that can capture that audio. Wouldn’t it be great if you could captures some of those sounds for later listening? You can. Your Mac is capable of producing sound as well as playing sound channeled from outside sources-devices plugged into the Mac’s USB- and sound input ports as well as audio streamed from the Internet. It might even still work with Soundflower. This is written for Soundflower, Quicktime, etc, but it all works with any audio recording app, or any virtual audio driver like BlackHole, JackOS etc. I can't find the link but the text is below. Macworld had an article years ago on how to do this. Say i want to play some audio in iTunes, but record it in Quicktime while listening to it out of the built-in speakers.I'm looking for a quick, concise tutorial but not finding one. In the meantime, you can take your chances with an older version of Soundflowerbed, but you can do a lot with a Multi-Output Aggregate Device.

NOTE: This is only the Soundflower kernel extension. Now you can follow the instructions above to get the 'Allow' button to appear in the Security Preferences. Then click the 'Open' button in that window to launch the installer. If so, click the 'Open Anyway' button which will display another window. (**) If you see an 'Open Anyway' button in the Security Preferences, this is something different!!! Most likely because you tried (and failed) opening the installer by double clicking without holding down the control key.

If the 'Allow' button is disabled, you may need to click the lock icon in the bottom lower left corner first. It should inform you installation was successful. Once there, there should be an 'Allow' button (**) that you will need to click on to give permission to use Soundflower (developer: MATT INGALLS). The first time you run the installer (Soundflower.pkg), it will ask for your admin password, and will FAIL! A security alert will appear, with a button to take you to System Preferences 'Security & Privacy - General' pane. Note that the even though this Soundflower extension is signed, but the installer is not! You will have to hold the control key down to open the Soundflower.pkg installer for the first time.Īpple makes you jump through a few hoops.
