The superb iRig mic plugs right into your iPhone/iPad, costs roughly $60, and is available at your Apple store.
If you shoot video on your iPhone or iPad you know how hard it is to get good quality sound. The same holds true if you're recording for Sound Cloud or Garage Band on those same devices. The built-in microphones just weren't made to capture sound well.
The iRig Mic is a great way to give your video or audio productions the sound they deserve.
This microphone is solid but lightweight, has a built-in wind screen, and captures superb quality audio at three different settings.
The bottom one is perfect for recording live music that usually registers as a hot, fuzzy mess on your iOS device. This setting tamps down the sound so you can actually hear your favourite band on playback.
The middle setting is good for recording sound within a a foot of the source. This is good for streeters or video interviews with people where you pose a question, then hold the mic close to your subject to get their thoughts.
Finally, the top setting puts the mic in ultra-sensitive mode. This is perfect for events where you're either far away from the source or the source audio is weak and you need all the boost you can get.
I've tested this ultra-sensitive setting in situations where I was about 15' away from speakers at a press conference and the difference in sound quality between the iRig and the built-in iPhone mic was incredible. The iPhone's mic's sound was weak and frankly compromised the viewability of the video, whereas the iRig-recorded sound was bright and clear.
I've also used this mic in a noisy construction site where I need decent quality sound on a subject's voice. Placing the mic about 2 ft away from the subject - again on the top setting - cut through the din and gave me decent quality sound. A little hot, but perfectly listenable.
My son has used this ultra-sensitive setting to record voice and guitar in our sunroom, positioning the mic on a low table about 3-4 ft. away and it worked well.
The iRig mic also lets you monitor sound quality by letting you plug a set of headphones.
Check out this great, inexpensive microphone at your local Apple or music store.
