Completely Wireless System Tuning - Theory???

***I realize that what I am about to propose will sound absurd, but let me explain my situation.  I am currently working as a mix engineer with a band that does primarily international touring.  I very rarely (almost never) have access to a tuning rig, much less the time to set it up... and even if I did I don't typically have access to any of the system processing anyway. Despite this situation I would still like to grow in my tuning skills and understanding.***

So here is what is rattling through my brain.  Basically what I want is a Smaart rig on my iPad with no wires attached to the system.  I'd like to utilize a dual channel transfer function as well as view the coherence, impulse response, delay time, phase, etc... of whatever it is I'm measuring..... again, with no wires attached. 

I just described every audio guys dream... and like I said, I know it sounds absurd. But my question is have you actually put a lot of thought in how this can be accomplished? I believe with technology the way it is now days that it will someday be possible.  I've been thinking about it a lot lately and am wondering if there could be a jerry-rigged way about doing it.  In theory, I could create a internal loop of pink noise in an iPad and have that be a "reference" signal and then run a separate signal of pink noise through the PA and attach a measurement mic direct to the iPad (usb mic or something) and have the software compare the two.  Obviously the problem lies in having the same exact pink noise played through both signal paths.

I know the tools themselves exist, but can any of you think of a way to make this work?  Obviously there would be limitations, but that's why I'm here.  Is there a way to make apps like AudioTools or ioScope accomplish this?

I know this sounds crazy, but hey... innovation :)

Justice C. Bigler:
As far as I know, there is no way to get a wireless mic like the Lectrosonics unit into the iPad without first connecting to a USB/Lighting audio interface. There are a couple of iOS mics that attach directly to the iPad, but no dual channel version that I know of.

And forget about getting more than two traces. the iPad doesn't have enough CPU power for more than two.

You can get a two channel USB interface and use the lighting camera kit, or an audio interface specifically build for iOS connection and connect that to your iPad and use the dual chanel FFT version of the Smaart Tools by Studio Six. That's about as light eight a a measurement rig you can get.

Lyle Williams:
Audiotools transfer function does this.

Line 6 wireless like XD-V55 or -V75 work for measurement.

Maybe you need to start planning for multichannel with proper Smaart - isn't large venue tuning sbout getting ok sound everywhere rather than awesome sound in one place?

David Sturzenbecher:
Or just VNC into a real computer and interface.... look ma! No wires!
