That’s good to know. I’ve only used REW with the A8, which is pretty straightforward. How does one run REW with an external file? Is there a delay function that waits for the tine before taking the reading?
I think you should be able to export it out of REW, you would set it to use external timing reference. The file would have a chirup sound which then triggers it to capture when it plays. I’m sure REW has something for this it’s pretty standard for DSP apps these days.
