This is what I mean by "distortion"

"sounds really clear" is what I was hoping you would say.
The simplest form of ADT is simply a second copy of the original track that has been delayed a little.
You can create this effect easily in Audacity by:
Selecting the track then press Ctrl+D to make a duplicate
Switch to the "Time Shift" tool (F5 key)
Drag the copy track a little to the right
Go back to the normal Selection Tool (F1 key)
Adjust the volume of the "delayed" track as required. The second track would usually be delayed enough to be noticeable, but not so far as to create a distinct echo - something less than 50 milliseconds.
For a slightly thicker and more complex sound you can make 2 copies of the original, delay them each by different amounts and pan one a bit to the left and the other a bit to the right. Leave the original in the centre and adjust the levels so that the overall voice effect sounds central. Use the "pan" slider on the left end of the track to pan the sound left/right.
