Thanks Dominick.
The mic and speaker in a room is kind of what I figured would be the scenario in a reverb chamber...just wanted to make sure.
I didn't like this idea at first, thinking I wouldn't want to put an expensive speaker and microphone in a room that might get flooded, but then I could use a cheap speaker and microphone, but then that would probably cause bad distortion, but then it doesn't have to be under ground, and it doesn't have to be concrete, and now I see the possibilities are many.
Along with the live room space, which will have various acoustic properties, I will also have an insulated shop building with concrete floor. Maybe I can use that as a reverb chamber? It will be within a short distance of my live room conected by a hall seperated by 2 doors.
I will have so much insulation and such thick walls, double wall in the main parts of the studio, that outside sounds shouldn't be much of a problem.
Most that I do know, or have some understanding of related to studio acoustics I have learned from this web site.
I'm out of breath.
Thanks everyone for sharing your wisdom...with people like me.
