I attended a chamber orchestra rehearsal prior to a performance. Since the rehearsal was in a different venue from the performance, I couldn't make mic choices. Instead, I decided to create a mic comparison video. I compare the Austrian Audio CC8 and Oktava MK-012 in ORTF config, and a pair of Line Audio CM4s in something approximating ORTF. Because of the limited time available, I chose to keep recording rather than addressing the troublesome rumble at the source (I believe the conductor podium transmitting through the floor to my C-stand). 00:00 context 00:38 mics 01:13 venue, orchestra 01:43 preamp levels 01:56 piece (piano concerto) 02:30 rumble, sigh 03:23 loudness analysis, adjustment 05:05 1: MK-012 05:58 1: CC8 06:51 1: CM4 07:46 2: MK-012 07:57 2: CC8 08:09 2: CM4 08:21 3: A/B all mics 09:17 HP filter for rumble 12:00 4: MK-012 13:16 4: CC8 14:21 4: CM4 15:26 end
