I taped with real equipment from 79-93 and then largely stopped. In 2014 I started using an iPhone and Zoom lightning connected microphone to stream, first the IQ5 then the IQ7. I went back to full taping in 2015 and don't hand stream much any more, I use the sonicport from my deck. I have also done some mixpre-6 -> iphone streaming using a lightning to USB-a cable. I did a lot of research trying to figure out how to do the deck to iDevice thing for streaming. It's possible there are new alternatives, but the general choices have been deck to iphone via the headset port using TRRS cable, which is mono only, using an older 30 pin connected iphone microphone from Tascam which has a 1/8 inch in, or the sonicport. I gravitated towards the sonicport because I wanted it to be stereo but thats really overkill for a stream. There are now a handful of people using the sonicport. Ive run across a couple who use the headset port also
It's possible one of the devices that have been released since Apple removed the headset port, headset to lightning adapter kind of thing works, like the Belkin one, but reports are that they generally dont support audio in...
I also have D:Vice, which is a A/D device specific to DPA microphones. Its a small round device that also connects to the lightning port.
