Let us take note here... someone said something about click/track - that is something which is either IN the mix or it is NOT IN the mix. You cannot control that whatsoever. I know a couple people will actually do their best to edit that out of IEM recordings but, uh, no way would I ever spend the amount of time to do that. And you cannot fully get it out. The more you mess with a recording the more it sounds... messed with.
I can hit a show and record like 4-5 mixes on average (always picking the best ones that sound most balanced but not all IEMs do). Remember, IEM's are tools for the musicians. Do I sit and spend the time to mix all that together in post to try and create something better than the original? Nope. But it is cool to see what one can record, record the best mixes. Sometimes if I have a couple extra minutes I will run Y adapters and do 'real time matrix' recordings of selected mixes and create cool mixes that way. But I rarely do anything in Post besides getting it ready for a CD (if I want to listen to it in my truck). The people who think IEM's are all laden with drop-outs, static and all sorts of annoying artifacts are... wait for it... correct. You can get to a show, be there for soundcheck but then get all sorts of interference from the physical members of the audience messing with the RF and your signal. Sometimes you have issues with brand-specific issues particularly if the antenna is too close (I know, it seems counterintuitive). Even if you are quite close. It is not a perfect science and anyone who conveys that it is definitely believes that the Earth is flat. But for the overwhelmingly most part, there is a night/day difference between RF/IEM vs just an AUD tape. These days, if I walk into a show with an AUD recording setup either they do not use IEM or I have multiple sources already recording.
I've seen this myth pop up quite a bit in discussion regarding IEM tapers. That there is a click. That there are several people who ship equipment to one another from this city to another. This, I will say, has happened and I have been on the receiving end of this a few times. But I am not involved in any sort of group. I am sure that people do this, for sure, but is that the norm? What is the norm? Beats me. I do not think that there is a secret society of IEM tapers who keep lock and stock on stuff. It's a great conspiracy related idea but I don't believe it is grounded in reality. I am the only RF taper I've met in person. I know several via the Internet - primarily one who shall not be named - is a lovely dude who knows his shit more than anyone. The dude is a Saint. But where are the others? I'm really curious how many other lone-wolf's are out there for RF taping? I don't want to trade with you, I don't want your recording (I have enough of my own to deal with), I just want to swap set ups and ideas. But I have yet to see a mafia militia of IEM tapers.
Taping, been doing this for 20 years. My first wireless was an ALD @ Red Hot Chili Peppers w/Queens of the Stone Age back in 2003. Since 2005 I've been focused pretty much exclusively on wireless. For fun, a couple samples for those that care or are interested. The Adele sample, I hit two nights in a row in Auburn Hills, MI. You hear the click track? That is her mix. It is to help keep her time. You cannot degrade the mix because the musician uses the metronome as it is to be used (I was quite far from the stage for these, like a football field+ length but they had a ton of transmitters for those shows. The Elbow show, Guy Garvey does not use metronome but good god what a great mix you know? Tool... they had two transmitters but only one person benefiting from it. Kind of a good standard for quality.
Lots of time, lots of practice, lots of money and lots of enjoyment. I realized 15 years ago that my taping flame would burn out if I didn't evolve. It hasn't and I did. My kids now come to shows with me and are 'in' with taping and understand what it is about.
