No this is definitely not advisable.
It is important to do click correction
before. hiss filtering. This is because the hiss filter will take the 'edge' off clicks and make them much more difficult to detect.
If the vinyl recording has been transferred via tape then the program will already be struggling to detect the clicks. If you still have the original vinyl discs you will get a much better result if you re-record them, leaving out the tape stage all together.
I sometimes use a combination of hiss filter and treble cut to take care of hiss rather than using a high hiss filter setting.
Yes, this is good advice, particularly if the original source is vinyl. The hiss filter should be used as sparingly as possible as it can generate artefacts. If you find that you do have artefacts, you should check that the 'noise profile' is suitable and adjust it if necessary.
My experience has been, if you normalize after filtering you bring the hiss livel back up with the content.
It shouldn't really matter whether you normalise before or after filtering. The filters work on 'relative' levels rather than 'absolute'. Of course if you have a quiet recording that becomes louder after normalisation then the hiss will be amplified along with the music. But relatively speaking there should be no difference.
Note, it's quite important to normalise
after click filtering. This is because a very large click would mis-calibrate the normalisation function.[/b]
