In the real world scenario I see students that are on campus will be recording in the band hall with equipment from the school and submitting. The real question is can you have much variety in mics or hardware using musicfirst? I'm assuming it should work with any device that would plug and play using audacity. I could see the use of something like a 'studio one' usb box with condenser mics used fairly easily if you had some technical ability. Most people would not easily have access to something such as this but as stated in previous responses any good judge will be able to not hold recording quality over the player too much.
