Review: Fostex AR-4i iPhone 4/4S Stereo Audio Interface

Jeff's Rating: 4/5

tl;dr: 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:

Fostex AR-4i Allows Stereo Recording with iPhone 4 and 4S [Updated]

[Update: I received a demo unit and put it through its paces: read my review of the Fostex AR-4i here. (Works with both iPhone 4 and 4S).]

Just found out about this new product through the YouTube grapevine:

Fostex AR-4i

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).
