In this feature I ditch the recording studio and take a look at the best portable interfaces for GarageBand musicians who want the freedom to record anytime, anywhere.

Recording With Multiple Microphones Using GarageBand. You can use more than one microphone or input device with GarageBand on your Mac. Instead of buying more hardware, you can configure your Audio MIDI Setup utility to create an aggregate device that treats each mic like a track in a single input.

The beauty of an app like GarageBand for iOS is that you no longer need to spend ludicrous amounts of money renting studio time or wait until your ‘big break’ to write, record and release your own music.

If you want your DIY music to sound its best however, you’ll need to ditch that inbuilt mic on your iOS device and invest in an audio interface of some kind.

There’s tons of choice out there and it can be hard to work out what interface is right for you. I’ve brought together 3 of the best portable recording interfaces on the planet to help you narrow down your options.

Let’s take a look..

Compact, portable, and easy to use, the Roland GO:MIXER makes it simple to record high-quality audio with your iDevice.

With multiple inputs available, you can connect a mic, musical instruments, and media players and mix them all together at the same time.

The unit features the ability to combine five sources at once via inputs for a ¼” jack vocal mic (no XLR input or +48 V Phantom Power here), guitar, stereo keyboard, and two stereo line-level devices (such as music players, drum machines, etc.).

The quality is great, assuming you don’t clip/peak the audio. There is a dial for each main instrument input as well as a master volume dial to adjust as appropriate. The GO:MIXER also has a peaking LED which is useful to have.

All in all this little box is incredibly versatile, though the lack of XLR input or 48v Phantom Power would definitely prove limiting for some.

The mic preamp used here series are nothing short of phenomenal, giving you clean and clear recordings every time. There’s also +48 V Phantom Power available, so you can use a studio quality condenser microphone to really push the quality of your recordings to the next level.

You can create Aggregate Device to increase the number audio inputs and outputs available at the same time. You can also use an Aggregate Device if your application doesn't support separate input and output devices.

With Logic Pro, GarageBand, and MainStage, you can use a separate device for input and output. For example, you can use a USB microphone for input and the headphone jack of your Mac for output. Some applications not manufactured by Apple don't support separate input and output devices.

Set up an Aggregate Device

When you create an Aggregate Device, make sure to connect all external audio interfaces first.

From the Finder, choose Go > Utilities. Open the Audio MIDI Setup application.
Click the Add (+) button on the bottom-left corner in the Audio Devices window and chose Create Aggregate Device.
A new Aggregate Device appears in the list on the left side of the window. To rename the device, double-click it.
With the new Aggregate Device selected, enable the checkbox labeled 'Use' on the left side of the Audio Devices window. Do this for each device you want to include in the Aggregate Device. The order in which you check the boxes determines the order of the inputs and outputs in applications like Logic Pro and MainStage. For example, the first box you checked will be inputs one and two, the second box checked will be three and four, and so on.
The list on the right shows the currently connected audio devices and the number of input and output channels for each one.
To use the clock of a device as the master clock for all the combined devices, choose the device from the Clock Source menu of the Aggregate Device. Choose the device with the most reliable clock.
If your audio devices all work with word clock, conne
