@jacksimmons to help with your searching the technique you are describing is often referred to as a “delay throw”
If you use the send method I describe make sure the delay effect on the bus is 100% wet - you only want to hear the delayed signal from the bus and NOT a mix of the original signal (Dry) and the effected signal (Wet)
Another great trick using the same technique is a “reverb throw” (the same setup but with a reverb effect) so you can saturate key parts with reverb
If you set the send on your original track to be “pre-fader” you can automate the send level increasing AND the fader on the original track being turned down
This will then reduce the original (Dry) signal at the same time as increasing the reverb, which gives the “man yelling as falling down a cliff” effect - this is especially effective on a bus with a mix of instruments when coming out of a big section into a softer section (eg “the drop”)
Using sends for fx can not only reduce the strain on your system (as you use the same instance of an effect on multiple tracks) but it can also make your mixes more “cohesive” by using consistent effects but in varying levels of “wetness” (ie different send levels)
There are also lots of creative ways of using sends
Finally - you can set up your effects busses as part of your track template when working on a song
When I start a new song I always have around 5 different reverbs set up and 2 delays (a short delay and a long delay) ready for me to send tracks to when mixing
