I'm looking to have a highly portable setup for binaural field recordings, and since I take my phone everywhere, it would be nice to use my iPhone as a recorder.
It isn't possible to have stereo mic input through the 3.5mm jack due to the fact that the three channels are divided up using two for output and only one for input, so I'd imagine this would only be possible with some sort of Lightning adapter.
I've looked around some, and I've found a number of stereo Lightning microphones, but no adapters. Does such a product exist? Is there another way to solve my problem?
