When you attach a mic to your iPhone or iPad, an audio interface is placed between your microphone and your iOS device. While there is a little more equipment (and money in this process), you have some advantages rather than using an iOS microphone. Let’s see about ways to connect an audio interface to a phone:
You can use a broader range of mics because you are not limited to a microphone optimized for use with iOS devices only.
You may use preamps to increase and color the audio more than a specific iOS mic allows.
More than one microphone can be captured at a time. The exact number of mics which vary depending on your input, but it is up to you and your bank account.
You can now bring more equipment and also have to find an autonomous power source for the audio interface.
If you’re going to have a four-piece recording band, you’ll need at least four inputs. If you intend to record a regular drum set, at least four mics would probably be needed — one for the bass drum, one for the snare, and two for the all-kit drums.
Of course, you should understand the audio interface components and why it is important to stick the device between your chosen microphone and your iOS device before you purchase something.
You can also use audio interfaces that are directly connected to your iOS device, even if you want to use your own particular mic. Different docks and interfaces allow you to directly attach your iOS device and provide you with the best of both worlds. If you buy a brand-new interface for your mics, consider these devices. One side advantage is that these devices typically control your iOS computer when recording.
Just because you have an older USB audio interface around you does not necessarily mean you can’t use it with your iOS device. You just have to do some research for using phone to connect an audio interface.
The trick is to use a camera attachment adapter. Apple can call it an adapter for camera connection, but it handles most class USB devices. Apple actually doesn’t want to ensure that it works on all cameras, so they cover up their bets with the permitted use of the camera.
Understand that this option is only available for iPad users because you must use one of these devices to connect your USB interface. And you are not guaranteed to use the audio interface – you must verify that it follows the Core Audio and MIDI requirements for iOS using the audio interface manufacturer. But here the benefit is that compliant audio interfaces can be moved from iOS devices to your own machine simply by removing the camera attachment package.
