I recently received an email from someone asking me how I got the voice recording in my videos to sound so clear and strong. The answer to that question is much more complex than I'll deal with here, but that person asked me mostly about the microphone I used, and if that could make a big difference in getting better recordings. Here's what I replied:
tl;dr: Great-sounding, reasonably-priced microphone, purpose-built for the smartphones and tablets, with few downsides.
The iRig mic was introduced in 2011, and promised to be one of the best ways to get sound from your mouth or instrument into the iPhone 4, iPod Touch or iPad/iPad 2. Since then, it has been tested to work with newer iOS devices like the iPhone 5, and many Android phones. I've updated this review (in 2013) to reflect my more extensive testing since I originally reviewed the microphone in 2011.
Perhaps you're tired of taking pictures with the DIY Greenscreen you just made, or you have had enough fun (for now) keying out backgrounds in Photoshop... but now you want something more. But you don't want to spend more than 2 minutes setting up for your next project. Well, how about a do-it-yourself mini macro studio that is made of materials you already have within arm's reach, and can set up in less than two minutes?
