Woah! I'm very curious about the acoustic properties of an upside down control room! I guess it removes ceiling reflections?

Do you have that upside down mic that was posted here about a year ago? Good fix make the whole studio upside down. We will have to send you some Vegemite now you are almost one of us  |

Send Sheilas and fewer architectural compliments !
Thx, the chunks really have improved the mid and lower bass a lot. I also put those long absorbers at top walls along side walls.
The 2 SC cost less than $100 cdn; money very well spent.

Gonna do another test? Graphs are like sfw porn for engineers.
Yeah, I said it.

The 11 is the front and back wall. I will get chunks for front corners done this weekend. I'll redo measurement then and post but show from 750 or so down so we see more detail. Thx again ! That's what I meant. The front and back walls are 11' so the distance between your side walls is 11'. Ie. The side wall is creating a null |

Good stuff mulmany. I've never understood how you find troublesome reflection points based on an IR. Below is a sample of one. From the example, how would you discover where in the room the reflection point(s) are that are letting this "Discrete Reflection" be so prominent so that you could fix it? Thanks if you can provide some insight!  Simple answer is a tape measure and calculation of the reflection path. This is done one speaker at a time. If you look at the delay time you can then find the distance traveled, sound travels @ 1130ft/s at 74 degrees. I usually take the direct path measurement and subtract it from the reflection path measurement then measure for objects that reside at that distance from the mic. The example is pretty nice and clear, in smaller rooms it gets harder as the initial delay gap is smaller. But this delay gap is very important to be larger then the space you record in, or you will never hear the acoustic coloration of the recording space. Hope that helps. This is what I do. I use a tape and calculate the delay. The other alternative is to reduce the volume 20db if you can't achieve an isd gap of 20ms. |
