Use acoustic timing reference with UMIK-1 and playing sweep files

[Mitchco]

Hi John,

Thanks again for your awesome software!

For some folks, the only way to measure in REW is to play sweep files on their music server that have been saved to file by the REW generator. Then have REW "use acoustic timing reference" on a separate laptop with the UMIK-1 and triggered when the chirp starts. Works great!

However, I have come across a couple of issues where the start of the impulse response is off by a sample or two. I notice in REW preferences, Analysis tab, Impulse Response Calculation group, the item "adjust clock with acoustic ref" I am wondering if this works in conjunction with the playing of sweep files on a music server?

Kind regards,
Mitch

Should do, yes, you can see any clock adjustment applied in the Info panel for the measurement.

Thanks John. I will give it a try.
