Hi guys,
I've been playing with REW and house curves and as I still have an acoustically horrible room I've come up with a question.
Because I have such massive room peaks after doing a measurement I lower the target line by 10dB, I pretty much have to if I'm to get anywhere near a decent curve. Unfortunately, I still have a very bad suck out in a couple of places but for now looking at the one at 46.4Hz this has filter 5 with 3dB of lift directly on it.
I stopped at 3dB because I've read many times how 3dB is the max otherwise something will reach the limit and clip. Sounds very reasonable at first. But my question is 3db above what and what is the "something" that will clip?
As I see it there are 4 possible overload (clip) mechanisms.
1. The electrical signal limit on the input of the BFD.
2. The maths algorithm for the filters.
3. The electrical signal limit on the output of the BFD.
4. The subwoofer itself.
I can, I'm sure eliminate (1) as this signal is not being changed. The sub (4) will surely pop or whatever if clipping. As for (3) well in my case with the filters on, the output here is a lot lower than it would be if the filters were off so I think we can (in THIS case eliminate) (3).
That leaves the maths algorithm. Is this what can overload?
If not, I can see no way for anything to clip even if I put another 5dB of lift at 46.4Hz.
What do yoiu guys think? Takes a bit of thinking about doesn't it?
Cheers,
Bob.
