Hi all, anyone got any recommendations for a interface to capture audio (ideally 2 track stereo) connected to my iPhone (iPhone 12) (from master out of desk or Akai force). I want to make a few short videos and ideally capture both film and audio on the phone for simplicity.
Cheers
Roland GO:Mixer springs to mind.
The ease of use is second to none. You’ll probably want a longer cable than the one it comes shipped with so bear that in mind 
Cheaper solution could be Behringer-UCA222, or if your desk/Akai Force has class compliant audio over USB, just use a USB to lightening cable direct into your iPhone 12, no audio interface required.
I’m still a newbie with iPhone apps but I would like to send audio from my Mac with Bitwig to my iPhone with loopy pro to sample directly in loopy pro.
Sending audio with a lightning/usb cable from iPhone to Mac is very straightforward but it seems more complicated the other way around as the iPhone doesn’t recognize the Mac as audio input.
I know I can save audio files and transfer them to the iPhone but I would like to do it live. So to do this it seems I need an audio interface. And the only audio interface I know that have two usb ports is the iConnectivity one.
Is there another audio interface that can do this, or is there another way to do this ?
The iConnectAUDIO4 is made for this. It has two device ports: one for your Mac or pc and one for your iOS device. I found a used one for €200.
I’ve just bought a Rode AI-Micro for this purpose. Very small. Can either be dual mono or single stereo interface and has headphone out.
I’ve also got an Olympus LS-3 field recorder which can act as a usb interface for either the built in mic or line/mic in port. It’s quite versatile. The newer models work too, but I like the mic capsules being in the main housing rather than sticking out. Also £60 secondhand was great.
Edit: sorry just remembered the ls-3 draws too much power for my iPhone 12 and doesn’t work. But works fine with my iPad Pro. It would probably work with an iPhone 15’s usb-c port too.
That’s interesting, so you just connect the usb port to the iPhone and a jack from the headphone out of the computer to the audio in of the interface ?
That might be a good cheap solution for me.
Are you experiencing any issues with clipping if gain is set to high on the incoming audio on the Røde AI-micro? Are there any visual notifications if it is?
It seems there’s two apps to monitor this, Rode Reporter and Rode Central.
The Rode AI-Micro comes with a short usb-c to lightning cable, which is what I use to connect to my iPhone. But a normal apple usb-c to lightning cable would do the job too.
I use the Rode app (Central I think) to set the gain to the lowest setting and put it in stereo mode. Then it’s fine for normal line levels. It does seem to run a little hotter than some interfaces so I think it’s worth monitoring until you’re confident with your setup. I’m taking the headphone out of the OP-1F so I have easy enough volume control. I’m using the ProCamera app to capture video from the iPhone camera with audio from the Rode AI-Micro. It has levels displayed within the app, which is very helpful to checking things.
If you can hold your GAS for another 1-3 months, Loopy Pro will become available for Mac: https://forum.audiob.us/discussion/57712/how-far-off-is-the-mac-version-of-loopy-pro
Thanks for the info, that awesome !
However I don’t think that solve my audio from Mac to iPhone problem. If I want to stay on the Mac I can do all the things I want in Bitwig, but I find the touchscreen and the small form factor of an iPhone very good for performance and new ideas.
This might be a silly question but wouldn’t a lightning camera adapter do the trick to send audio from a Mac to an iPhone via my motu m2 ?
I would be happy to not buy another audio interface if I can only buy a 10 euros adapter.
I don’t think you can split the data signal two ways.
But you can use the motu with a camera connection kit so you can provide power to the motu since the iPhone is not powerful enough. I would rather get a Røde or a Roland Go:mixer tjats dedicated for the purpose. I have tried several solutions and I use a
Roland:go mixer when recording my piano. The Roland doesn’t beee any additional adapters and can be powered by the iPhone. The TE TX-6 is also amazing but pricy but doesn’t requires any adapters too 
Ok thanks, I didn’t know about the Roland go mixer. I’ll think about it.
Sorry to update this thread again, but this is just to say that a lightning camera adapter works perfectly. I can now send audio from the computer to the iPhone via the motu m2 and a powered usb hub.
And for me this is epic.
I’ll add some info too, recently got usb c audio interface Arturia Minifuse 1, plugged it to a basic iPhone 15 (non pro or max), and it worked, iPhone supplied power to it, no need of powered hubs and all, it also supplied phantom power to rode ntg3, and in Apogees MetaRecorder it let me go to 96khz. So pretty cool too!
edit: apparently the saved file is still 48khz, will try with other apps and report if it’s possible to go 96khz, for those that are into sound effects recording.
Man my little second hand iPhone SE 2020 cannot compete.
iOS works at 48kHz internally, there are some music playback apps that claim to do higher frequency audio playback, so it might be possible to get an app that can record at a high frequency but my expectation would be that you’re limited to 48kHz and I wouldn’t spend too much time investigating it.
iPhone 15 can send power because it has USB-C but older iPhones with Lightning needs extra power. iPad with USB-C works also
