Any way to record only the delays created from any material?

As in the trail... leave out the original sounds that the effect was applied on?

Assuming you're using a plugin for the delay, you could:

 

Try setting the dry signal to zero

 

Or if you want the delayed signal on its own track, you could use a bus to an aux track with a delay plugin, then use that as an input on a new audio track, record enable, record, and the wet signal will be recorded to your new track

Thanks! I'll experiment with both
