I just read the following in another thread:
"In an excellent old post from TV. I read that the compensation numbers posted were only valid for 1/3 octave pink noise. I want to get a finer, more accurate resonse curve than that so I can set up the paremetric eq optimally. The Behringer has a tone generator, that has 1/60 octave steps. I'd like to just step through the whole range from about 16 Hz to 100 Hz in 1/60 steps, but I'm not sure how to compensate the readings for straight tones. Are the numbers I see in TVs post and elsewhere still good? (I'll interpolate linearly between the listed values - that should be close enough)"
Okay, this got me worried. I spent several hours the other night using the Autosound 2000 CD to put out straight tones at 16, 20, 25, 31.5, 40, 50, 63, 80, and 100 Hz, then used the published values to correct the RS SPL meter. I used the results to help determine best placement for my CS_Ultra, and then to set the EQ to correct for a couple of peaks I found.
Is it true that the correction values don't work for straight tones, only pink noise?
Okay, now I'm thinking your going to make me feel stupid and say that pink noise is a mixture of frequencies? And to apply the correction values, you have to output specific frequencies. So maybe I'm okay after all?
Learning is such a humbling process.
