Hi all--
Is it really as simple as it seems? Here's what I was planning for this 2.1 set-up, and am wondering if I'm missing anything.
1) Use my analog radio shack SPL meter, c-weighting, set on a tripod at the main listening position
2) Use a tone generator like
this nifty one I found online
3) Use the pink noise test tone with this generator and set the overall volume (with both L & R speakers and subwoofer operating) such that I'm at a reference sound level (e.g. 85dB)
4) Run test tones from 16Hz all the way up to ~20Khz, recording the meter readings at each frequency
5) Apply any dB adjustments based on known measurement errors of the meter
6) I now can graph the FR of my room
So what else am I missing? Anything else I need to be aware of, or take into account?
The tone generator allows you to generate sine waves and many other wave forms. I'm assuming sine is the way to go?
By the way, the receiver is a Pioneer 55TXi that allows me to plug a USB cable directly into it from my laptop. So I don't think I'm introducing anything there, am I?
As usual, thanks in advance for everyone's assistance.
Rich
