So i need advice on a potential microphone. Im needing a mic to record interviews for a psychology lab. It will be in a small room, and im needing it to pic up everything, every subtlety. We need to be able to hear everything since the recording will be transcribed and coded, so hearing every little sigh or hesitation is important. It seems as if condenser mics are the way to go, i also know they require phantom power which will require a small mix board. The professor over the lab said he wants the budget for the recording set up to be around $600, BUT, said he doesnt want to skimp on the mic. So im just looking for suggestions, i can research on google(which i did) for hours, but personal experience is invaluable.
