The 'pro' solution for such a scenario would be a wireless lavalier (being 'cabled' is probably not what you want while demonstrating martial arts), or a semi-gun on a boom. Semi-guns are the ones that are 35-45 cm long, price range $250..300. Even such a mic will not produce usable sound 30 ft from the speaker in typical gym acoustics, so you don't want it on the camera but closer. That means either a boom + operator, or someone sitting near the edge of the tatami holding and pointing it. If the speaker doesn't move too much you could also suspend it pointing down 30 degrees or so towards the speaker, but clear of the ceiling. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
