Cannot remove clicks

My Friends: I have made some audio cassette-to-CD music recordings with Audacity. I found lots of “clicking” sounds interspersed throughout the recordings. I tried Audacity “Click and Pop” effect to remove these clicks, but no luck. I then tried Cool Edit Pro’s “Click and Pop” eliminator to remove them, but the clicks are still there. Please tell me how these clicks are produced and how I can be rid of them. Thank you. Windows XP Pro.

If it’s from tape rather than vinyl then I suspect your clicks are skips.
Skips are usually irreparable as there’s a little bit missing. Prevention is the only solution.

Have a try with Brian Davies’ excellent Click Repair - you do get a 14-day free trial.
