If you have a Mac computer, a USB mic and an iPhone, you can use Rogue Amoeba’s program Audio Hijack and the FaceTime app to record an interview with a subject on their regular phone (landline or mobile).
- Hijack focusing on internet radio streaming and replacing.
- Mar 05, 2021 Set any application as your source in Audio Hijack, then hit the record button to save its audio! Grab Device Audio. Audio Hijack can also capture and record audio from microphones, mixers, and other input devices. Get System Audio. Use the System Audio source to capture all the audio heard on your Mac at once.
Many users of the new Audio Hijack 3 have asked about recording phone calls from their iPhone. If you’re using Mac OS X 10.10 (Yosemite) and iOS 8.1, it’s easy to record these calls with Audio Hijack. Thanks to a new feature called Phone Relay 1, you can use your Mac as the receiver for making and receiving phone calls. That can be handy on.

Configure FaceTime to make phone calls from your iPhone
You’ll need to set up your Mac and iPhone so that you can make phone calls on the computer. All the instructions can be found at this Apple support article.
Once you’ve done that, plug in your USB mic and in FaceTime go to the Video menu; under Microphone select the name of your USB mic and under Output choose your External Headphones.
Configure Audio Hijack
In Audio Hijack, you drag components from the right-hand menu bar and drop them into the workspace; move them around like building blocks to create the recording process of your choice. Here’s the way I did it:
Choose Application (from Sources) and set it to FaceTime. Click on the box and turn off “Include audio input” from the settings. (We don’t need it since we’re going to record directly from the mic.)
I’ve put in a Peak/RMS Meter (from Meters; not shown in screenshot) so I can see the levels as the call is recorded.
Choose Recorder (from Outputs) and add it to the chain. Click on it for settings and choose your recording format, file title, metadata tags etc.
Choose Input Device (from Sources) and add it to another line; click on it for settings and choose your USB mic for Audio Device. Download mawadata driver. Go ahead and add another Meter if you like, and finally another Recorder component so that your voice is recorded into a separate file from your interview subject’s recording.
Add an Output Device (from Outputs), click on it for settings and choose your external headphones. Move it to the side of both input device lines so that both inputs pass into it (meaning you can hear both your audio and theirs in your headphones).
You can also add a 10-band EQ component, a Low Pass Filter or other effects from under Built-In Effects.
If you’re hearing a delayed echo of yourself in your headphones, go to Audio Hijack > Preferences and set the Audio Processing section to “Lower Latency.”
Once you’ve set up Audio Hijack, go back to FaceTime, type in the phone number you want to call and hit return. You should be able to hear your subject talking through your headphones and they should be able to hear you through your USB mic.
Return to Audio Hijack and click the red record button at the bottom left. This will start recording the output from FaceTime into one file and the input from your mic into another one. When you’re finished, you can hang up in FaceTime and hit the red button again to stop recording the session.
The recorded files can be accessed from the Recordings button at the bottom right. On that window, the Actions button will let you reveal the file in the Finder or edit it in Pro Tools or whatever other DAW you select under Audio Hijack > Preferences.
Here’s a snippet of the raw recording I made of my interview subject talking on her mobile phone through FaceTime on my computer. Keep in mind this method will not sound like a studio recording; it’s obviously phone tape, but it sounds much better once you play around with EQ or a filter in your editing program.

- You can also set the Application component in Audio Hijack to record both the input and output from FaceTime into a single stereo file (which means you don’t need to include the USB mic as an Input Device), but that will put outgoing audio on one side and incoming audio on the other channel. You can then split the stereo into two mono tracks for editing purposes. However, I prefer my method above so I can have each side of the conversation recorded into its own separate file instead.

HiJack is a hardware/software platform for creating cubic-inch sensor peripherals for the mobile phone. HiJack devices harvest power and use bandwidth from the mobile phone's headset interface. The HiJack platform enables a new class of small and cheap phone-centric sensor peripherals that support plug-and-play operation. HiJack has been tested with the iPhone 3G/3GS/4G, iPod Touch, and iPad devices.
Power. The HiJack energy harvester can supply 7.4 mW to a load with 47% power conversion efficiency when driven by a 22 kHz tone from the output from a single audio channel on the iPhone 3GS headset port, all using electronic components that cost just $2.34 in 10K volumes. We are exploring other approaches for achieving higher conversion efficiencies.

Data. The HiJack communications layer offers two data transfer schemes. The first allows 300 baud data transfer using Bell 202 FSK signaling. The second offers 8.82 kbaud using a Manchester-encoded, direct-digital communication using hardware accelerators on the HiJack microcontroller and a software-defined, digital radio modulator/demodulator on the phone. The first scheme is described in the ISLPED'10 Design Contest entry (below). The second scheme is described in the DEV'10 paper below.

Sensing. We envision a range of sensorboards including ozone, carbon monoxide, DVM, blood pressure, blood glucose, and others. But today, we only have four daughterboards: (1) a simple demo board with temperature/humidity sensors, PIR motion sensor, and potentiometer used on the early HiJack prototypes; (2) a 3-lead EKG sensor; (3) a basic soil moisture sensor; (4) a breakout board for fast prototyping on the latest generation of HiJacks.
