I hope this is an ok place to post this question.
I do a lot of live classical recording on location. As a part of the job, I often have to place microphones in locations that aren't exactly perfect due to aesthetic considerations.
I have a relatively new client where I absolutely must have my microphones as close to the floor as possible (It is opera and there are sight-line/aesthetic issues with microphones). To do this, I have my mics on small (4-5") stands. The biggest problem with this is the reflections off of a hard stage floor can really affect my sound.
To get around this, I've taken some generic foam and felt and placed it under the mics. It usually succedes in taking a bit of the bite (high end) off of the sound in the mics which is a good thing. I'm sure, however, that there are better acoustic products out there for the job. Basically, I need a low-profile black absorptive surface to place below each of the microphones. It can be up to about a square foot in size.
Anybody have ideas of what I could use that would work for this?
Thanks!
