As pokopiko said, I've also tried all these restoration softs and nothing special about a particular one or other, except Clean! 3.
Great soft.
Recently I've tested MAGIX audio cleaning lab 1.03 and finally something a bit new in the scene.
MAGIX acl is fast and brings a good all-in-one solution.
Declicking, denoising, decrackling, dehissing, stereo enhancement, compressor, EQ, Direct X support, auto track marking recognition and audio CD recording are in the pack.
Plus, you can import wav, mp3, or record direct from soundcard's
line input or rip an audio CD. You can export to wav, mp3 or burn an audio CD.
Try it and also Clean! 3. Don't spend all your efforts on Algorythmix.....
Good luck!
