Re: REW: time sync issue for impulse response


Hi John,

I signed up to this forum, after which a search link emerged, so I exactly found what I was going to post about ... this thread.

I have been trying what you suggest here, but IMHO it just can't work like that. Not when all first largest peaks are mapped onto the 0 point ... Think of this :

When there is two drivers in a cabinet, and you want them perfectly aligned (physically shifting) including (filter) electronics behind them, I'd need to know the relative arrival times of the first stroke.
There is IMO no way of letting the both (etc.) drivers play at the same time at measuring, because the picture can't be interpreted because of adding (etc.) waves then. The only thing which -with a long shot- seems a bit possible, is first measuring one driver, and then add a second, where the first one is to be interpreted as a reference (plot). But then too, the impulse plots of either driver change because of the both interfering with eachother.

I know, this is ROOM equalizing software, not speaker alignment software. But I thought it would be so easy to just let the plots start where they do (as an option), instead of mapping all to one 0 point.

Thank you, and thank you very much for great software !
Peter
