Hey, I'm trying to film something that won't require professional audio, but has to be a bout more than an on-board camera mic. I'm wondering if I could plug some lavalier microphones into these devices: http://www.ebay.com/itm/3-5mm-Bluet...rg=20140131123730&rk=1&rkt=15&sd=371053013537 so that I could transmit the audio onto my iPad mini and link it to the video later. Would it work? and if it would, how many transmitters do you think could connect to the iPad at once before the bluetooth would get overloaded? Would an audio recording app be able to receive audio from multiple input devices at once, or do they pick one? ...so many questions... if you can't already tell, I'm pretty clueless in this area.
