I have treated my room a la fiberglass cloud on ceiling, and left the floor live. I like a bit of liveliness since I mostly record acoustic guitar in ORTF with some omni's. I took Ethan's advice from his faq on this and decided I'd try it with the cheaper rigid fiberglass bass traps on the ceiling with coverage at about 80%. Re-reading Ethan's faq, he mentions that the dead-ceiling, live floor is great for recording acoustic material... but he also mentions it's when you put your mics up near the ceiling and point 'em down like the images I see in Ry Cooder's sleeves for his Cuban material. Overhead style you could call it I guess. So I tried this last night. I put the SRO's up near the ceiling (about 7.5 feet up, just under rigid fiberglass panels), pointed them down and played under and slightly in front of them. it sounded fantastic. I was floored. Compared to putting the mics right in front of me at guitar level as I stand, it sounded really nice, i.e. the "room sound" was better than anything I'd gotten to date. I wasn't going for a close-mic'd sound... I wanted some room sound, and this did it better than simply putting the mics right in front of me, parrallell to the floor. Why does this sound so much better than slapping the mics right in front of the guitar? Any acoustical reasons? And, when recording a live performance of my singing and playing guitar together, is this a preferred approach/standard practice over just putting the mics in front of me, with the height between guitar and my mouth? Just curious about standard practices when recording "overhead" like this for folk singer style material. I know I like the sound, but I'm curious about why it seems to sound better than recording straight on. thanks!
