Optional steps: Add tools or effects for doing steps 2 and 3:

Remove DC offset - either use Effect → Normalize (without amplifying) or Brain Davies’ deNoiseLF

de-rumble - either high pass filter or combine this step with the previous using deNoiseLF

de-noise - use Audacity effects or external tool like deNoise

Personally, I perform these steps using Brian Davies’ tools right after ClickRepair. I import the final result back into Audacity for step 9. Because I run through the sequence of external tools my files are named ‘*-cr-dr-nr.wav’. I prefer to run ClickRepair first. I feel it’s got the best chance to finding clicks on the original recording before any other processing has had a chance to mess with it. Maybe someday I’ll really test this by doing the same file both ways and see if there’s a difference.

Interesting - you seem to have changed your mind about the order of processing here. When you responded to my thread on ClickRepair Click/pop removal - ClickRepair software back on 23Jul08 you said back then that you did deNoiseLF first, then ClickRepair and thirdly deNoise (and this is the order that Brian Davies recommends in his manual and thus what I based my suggestions on in the tutorial - as I personally don’t use either of the deNoise functions or their equivalent in Audacity). So I’d appreciate a fuller understanding of your change of mind in regard to the order of processing.

Thanks for the feedback - points all well taken - I will have to restructure the tutorial somewhat following other feedback from Gale Andrews on the Manual editors mailing list - so it may take me a couple of days to get round to incorporating your feedback.

Thanks,
