Five stars for the capabilities, four for the fit and finish. It's a great tool, but not without a few rough edges. (See note about iPhone 4S compatibility).
[UPDATE on iPhone 4S compatibility: I've heard many reports of people having trouble with the AR-4i and the iPhone 4S; my own usage indicates that there is one quirk with this combo: the wireless signals on my phone go away while plugged into the AR-4i. Example recordings with various firmwares below:
Just found out about this new product through the YouTube grapevine:
The Fostex AR-4i is said to allow for multiple microphone input, and works with the iPhone 4's dock connector. It looks like a rather klunky device, meant more for handheld use than any existing tripod mount (unless the device has a tripod mount on it, which would be handy).
It also looks like there's a built-in level meter and headphone jack (hopefully with selectable input/output levels...). It comes with two rather robot-like mic arms, which might be nice for recording concerts. I'm presuming one would need to use a Fostex-provided app to record in stereo (I don't think Voice Memos of FiRe, for example, allow two-channel recording).
Great-sounding, reasonably-priced microphone, purpose-built for the iPhone/iPod touch/iPad, with few downsides.
The iRig mic [Amazon.com] was introduced a short while ago, and promises 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.
Apple's announcement of the iPad 2 today left me speechless in many ways, but maybe the most promising and awesome announcement was not the iPad itself, but rather iMovie and GarageBand for the iPad.
One thing that I've constantly had to do for video production is lug around my Mac, a camera, cables, etc., just because there was nothing that was as easy as iMovie to quickly hash out a video, with voiceover, etc. The iPhone's iMovie app is just not good enough for me, though it's great for a quick YouTube edit.
Luckily for me, all the work I've done in testing microphones and audio input adapters for the iPhone 4 applies directly to the iPad 2's audio input. You'll still need an adapter to get the audio into the TRRS input jack on the iPad, but being able to record to 8 tracks using GarageBand is completely amazing.
In the past few months, I've finally had time to post more information about two projects I've worked on in the past year or so at the Cathedral Basilica of Saint Louis—both of them having to do with the sending and receiving of video and audio signals through a very large building.
In this article, I explain how we sent crystal-clear audio (used for both communication/VOX and broadcast TV) over a distance of about 300' using nothing but shielded Cat5e cable. Pictures, diagrams, etc. included.
In this article, I explain how we sent very sharp high definition video (up to 1080p) over about 100' using component video baluns and shielded Cat5e cable. (You can also use these baluns to send digital/coax audio).
I truly believe Cat5e cable to be the most versatile cable on the planet. It can be used for almost any kind of data or signal, and is extremely cheap over long distances, in comparison to most other cable types.
The new Blue Mikey (2.0) will not work with the iPhone 4 or iPad. It's a big letdown for me, as I don't really care if Blue can support previous-generation or outmoded equipment with their mics.
Their CEO, John Maier (no... not John Mayer...) said their engineers are hard at work increasing compatibility with iPhone 4 and iPad. Great. Maybe we'll see the Mikey 3.0 next year sometime. I'm not holding my breath.
I guess I'll stick to my own setup for recording audio on the iPhone 4. I was really hoping this Mikey revision would allow me to leave all my cables and mics behind, and stick with the Mikey alone, but that's not the case.
Technically speaking, the Mikey is made 'for iPod' - but why doesn't Blue see the massive potential for selling a professional audio recording device for the iPhone. Judging by the huge amount of traffic I get on my iPhone recording series, they'd get a bit of business.
