Just change the speed of the delay, or it might be labeled "time", you can slow that down or increase it. Some delay units have an option for a tempo based time or just an internal clock speed, you can do that, and then just automate the on/off button in your DAW's virtual mixer board so that you can control when the delay applies. As for the part with the fading/decreasing frequencies, just add an EQ with HP and automate the high pass to make its way up the frequency spectrum as the delay goes on.
Also, some delay units may not have an option for time/speed of the effect, or it may not be all that apparent as to how to do so (such as the presets are obvious changes in speed, but you can't figure out how because there isn't a button that says "speed or time"). If that's the case, your delay unit sucks. Go find a new delay effect plugin.
