While I was looking for a stereo mic for my 7D I visited a store that had Rode mics, including a unit that plugs straight in the bottom of an apple device, they have an app for it, I don't know if it has manual level control, but the actual mic bit looked really good. Kinda wish I'd gone that way instead of on camera, it just seemed more complicated at the time, but I almost always have my phone with me and the iPhone mic is much smaller than the dslr mic.
I'm mostly curious about the auto-levelling audio recorders they've used and how they managed to get usable dialogue from them... I'd love to get hold of a tiny non-levelling recorder but the best I've found is the not-so-tiny zoom H1, any suggestions from anyone else? Are there maybe apps for it these days? I have an iPod Touch 5 - I'll have to look into this!
