Stereo Tool

Well I didn't say it's not needed, I said it *shouldn't* be needed. Even with the worst, 15 euro battery powered transmitter that I have ever seen, which drifted over the frequency band as the battery started to run out, the current calibration can make it nearly completely flat. Since you can only setup something like this if you have a modulation meter (and even with one it's really difficult to do it, especially to get the phases right), I think it's very rare that people would have a transmitter that's worse than the one I just mentioned, but they do have a modulation meter and the knowledge to configure it properly.

So what is it that you cannot do with the current calibration? I kept it in because the code exists (I wrote it at the time because that horrible transmitter was the only thing that I had), and if someone really needs it it's at least still there. But given how bad that transmitter was (phase effects of more than 90 degrees, some frequencies in the middle of the range needed to be reduced by more than 9 dB while others needed to be boosted), I don't know what more could ever be needed.


A real square wave will constantly show massive overshoots, so we used a smoothed square wave. It's difficult to properly generate a square wave at higher frequencies with this smoothing. And since the main goal is to find tilt, it's not really needed on higher frequencies either.
