I'm looking for a way to record a live dance class in a 25' x 20' space. I want the classroom ambience but also want the teacher's voice to be clear. I'll be using a PA system either in the back or front of the class. I'll be routing the output of the PA system directly into a computer and likely mixing that with a room mic to add the classroom ambience. Is there a suitable microphone that, if placed properly, will pickup a teacher at the front of the class as well as a robust room ambience? The teacher will be located between 3 and 10 feet from the microphone. The teacher will also face the microphone as I intend to mount this microphone on the wall towards the ceiling. I know I could mix a room mic with a fitness mic (something the teacher wears), but I'm wondering if there is a suitable mic that would remove the need for two mics.
In addition, this recording takes place in a dance studio in which almost all wall surface area is covered in mirrors. What considerations should I have regarding this environment when choosing a microphone?
Thanks for reading
