I'm looking for some technical advice for a correct voice-recording setup using a pro-level lavalier mic for speaking (no video)—like a RØDE Lavalier, for instance—with input into either a laptop with a 3.5mm port or via some bluetooth setup into a smartphone without a 3.5mm port (iPhone XR).
In my research I have seen several problems which I do not know or am unsure how to fix:
- Some high-quality lavalier mics require phantom power. Obviously for my setup I would not have phantom power, only "plug-in" power.
- The 3.5mm port on my MacBook Pro (for instance) has a TRRS setup, but most good mics I have seen have a dual-mono TRS setup. Not sure how to deal with that.
- I would prefer to record into my phone. But since there is no port, I was looking into a bluetooth transmitter/receiver combo. The idea is the transmitter and receiver act as a wireless mic, and the lavalier plugs into the transmitter. Then the receiver connects to the recording device via bluetooth. I'm not sure if/how this would work and how compatible it is with a lavalier.
- I have heard warnings about sound cards on computers/smartphones not able to capture high-quality sound. The last thing I want is to spend a several hundred dollars on a good mic only for it to sound trashy in the recording b/c of the recording hardware.
I would really appreciate some ideas to get from voice, through a lavalier, into a phone/laptop with high sound quality intact, and in such a way that the speaker can move around (not tethered by a cable).
Thanks for the help.
NOTE: I do own a decent, smaller sized mixer that could be used if necessary.
