Something about this realm fascinates me, and hardware vendors keep obliging!
Several worthy candidates easily plug in to your iPhone. Here are some recent articles extolling the virtues:
It’s important to note that even with the finest mobile recording environment, it’s not likely that an iPhone mic will ever match the quality of your home recording studio. But in a pinch, I’ve heard of clients certainly accepting auditions that way, and even an occasional final cut being accepted from an iPhone/iPad/Android Device recording.
That’s why 3rd-party hardware designers keep coming up with ever-better devices.
Zoom is a favorite of mine in this area. The Japanese firm has a plethora of products on the market. I personally think their H6n stand-alone portable field audio recorder is the best you can buy, and has served me well in the field.
The iQ7 is a full-featured mid-side stereo condenser mic that plugs right into the lightning connector on your iPhone 6 or 7 series.
You get a large manual front-facing gain knob and an LED meter, along with a dedicated headphone jack that doubles as a line output.
According to their features page, Zoom says the “…The iQ7’s rotating mechanism ensures correct left-right stereo orientation whether you’re creating audio-only recordings or capturing audio for your video…”
Zoom also makes available a free iPhone app for recording that lets you choose recording formats, add effects, and offers different ways to share your recording.
What is mid-side recording?
Again from the Zoom website:
Mid-side is an advanced recording technique that allows the width of the stereo image to be varied, even in post-production.
The two microphone elements in the iQ7 include a directional “mid” mic that captures signal coming from directly in front of your iOS device, and a bidirectional “side” mic that captures the audio coming from both sides.
A three-way switch allows you to select between 90° (to focus on sounds coming from the center) and 120° (for a wider image that includes ambience and room signal). A third setting, labeled “M-S,” enables you record the audio “raw” and adjust its stereo width afterwards, using Zoom’s free downloadable Handy Recorder iOS app.
Retail for the iQ7 is about $100 no matter where you buy it.
When I get mine, I’ll try to post some soundfiles here to give you an idea of it’s practical usability in today’s VO marketplace.
