The end result
However you choose to record your audio files, you should end up with a bunch of MP3 or M4A files that you can label and listen to later, either for transcription or just as a record of what was said by whom. You can keep these in folders or as playlists in iTunes. You can also record FaceTime Audio calls by using a free application called SoundFlower, which is able to route audio internally between applications inside your Mac. However, this does involve setting up and configuring some custom virtual audio devices in the Audio MIDI Setup app, so it’s something that’s perhaps better attempted by experienced users. For the outlay, the Call Recorder or Audio Hijack apps provide a cost-effective and quick solution to call recording, especially if you do a lot of it.
