How do I launch FFT Analysis?

Getting Stuff Done How do I .... ?

OK, I’ve built Ardour2 with FFT_analysis=yes, but can’t figure out how to use it…

So what’s the obviously simple, but overlooked (by me) means to my end?

right click on a region and choose “analyze region” from the pop-up menu!

cheers.

You can also right click on a range selection and select “analyze range”.
