Hi Derek,
Allow me to say that you have made an old Vietnam Vet extremely happy! I have Lp's from that era which are very dear to me, and now I can make recordings which are better than the first time I played the disc.
1. Am I mistaken or is the program more likely to miss a large click (looking at the waveform) if the surrounding area is relatively quiet? Can allowances be made for this condition?
2. Is it possible to have the software search for the extreme changes in amplitude relative to time and then make the parameters flexible? If one still heard clicks and crackles in a certain area of the music he could then find these changes and decide if they are music by looking at the waveform. Nailing down the exact location of offending noise would then be less time consuming.
