Audition effects are causing click artifacts

[scm28]

When I add effects I often get a clicking or short crackle/pop to vocal tracks.  I thought it was possibly a lack of computing power in my old Macbook Pro but no, I'm now using a very powerful Mac and still they come up.  I'm pretty frustrated about this and had high hopes that a new computer would solve it.  I'm crestfallen that it has not solved it.  If I disable or remove the effects, no more clicks/artifacts.  If I replay the part that clicks a couple of times that click might go away.  It's not clipping and it's not on the original recording.

Try increasing the buffer size

As well as increading the buffer size, try pre-rendering the effects you are using - especially if they are heavy-lifting ones like reverb. Use the little lightning bolt at the top of the rack effects box to do this. Yes, it's undoable but makes playback a lot smoother.

Steve, just to be clear, I CAN undo a pre-render of the track or cannot?  The use of the word "but" makes this unclear - thanks for your help!  Also is there a way to "render" and do the same thing to a track to get rid of the punch and roll artifacts leftover so I can edit without uncovering the junk recorded over tracks underneath?

You can always undo a pre-render. If you feel happier swapping 'but' for 'and', that would be fine... No, it only works on effects - it doesn't alter the status of the junk at all, I'm afraid.
