Jason Snell's podcasting setup is similar to mine – he wants to hear his own voice, record his local audio track and have a conversation with several people on Skype, who must also hear his voice from an external microphone. And he wants to use a computer to do everything. Now he has figured out how to podcast from an iPad Pro using an additional USB interface:
Lately, I have done something similar using the Audio-Technica ATR2100-USB, a microphone that can send out one digital signal uses USB and an analog signal via an XLR cable at the same time. The problem is that the last time I tried to use the ATR2100-USB with the iPad Pro, it didn't return my own voice to my ears, which meant I couldn't judge the sound quality of my own microphone. After years of having my own voice back to me, I strongly prefer not to register not to hear my own voice. (I use earphones that largely shut out sound from the outside world, so the experience of talking while not hearing yourself is even more profound than it would be with leaked earplugs.)
This time, I wanted everything, or at least as close to everything that i can get with iOS in the mix: An untouched recording of my own voice, the same high-quality microphone sound also extends over digital to my podcast guests via Skype and the ability to listen to both my guests and myself simultaneous.
Takeaway from the story is not that Snell wanted to prove a point despite Mac users – it was that he could travel with a computer instead of two (he would have used most of the same audio equipment with a Mac and that he found an expensive but genuine solution for professional podcast recording on the iPad Pro
I currently do not have a USB audio interface like Snell's USBPre 2, but I may have to buy one before the summer so I can record podcasts from our beach house with only iPad Pro. (That is, provided the iOS 13 beta I've installed at that time doesn't have meaningful improvements for audio workflows.)
