I'm looking for a way to perform relatively high quality stereo line-in recording on iPhone. Unusual and third-party hardware is acceptable, but jailbreak is not. I am aware of the following options:
- Pros: Well-reviewed, USB interface.
- Cons: Lightning to USB Camera Adapter is not supported on iPhone.
- Pros: Works with iPhone.
- Cons: Requires Lightning adapter, line-in quality reportedly poor.
Neither of those satisfies my requirements. Is there some workaround I'm missing?
