I would agree with Graham that the CEDAR tools are not expensive if you
are restoring audio professionally. Consider how much your time costs
and then consider how much time is saved by using the right tool.

Having said that, there are probably hundreds of alternative options
that are not mentioned in your article. Algorithmix actually wrote the
Waves software you mentioned and you can find their technology at a
lower price in a number of other products and also under their own name.
Every general purpose wave editor and CD burning program seems to have
some kind of noise reduction built in.

However, for your purposes I would suggest that you look at Cool Edit
Pro. This has the spectral view which makes it easy to find clicks and
then a select, button click to bring up dialogue box and button click to
remove glitch process for each glitch.

2 or 3 years ago I tried the demo versions of just about all the glitch
removal software that I could find (except the really expensive
hardware/software) and I felt, like you, that most of it was cumbersome
to use. For most basic noise reduction purposes I found that Cool Edit
Pro worked as well as anything for the occasional transfer that I have
to do.

Cheers.

James.
