I’m doing some pseudo mastering on a project done with a 4-track cassette. One of the obvious issues is tape hiss, particularly on softer tunes. I’ve tried the following:
- input file is 96/24
- insert Sonnox Denoiser in effects slot
- highlight about 1 sec of ‘silence’ in at the song start, leave sensitivity at 0 and attenuation at -4.5dB
- switch from adapt button to freeze button
- reset audio window to start of file
- render out with no resolution changes (ie use channels/sample rate/wordsize from input stream).
I can clearly hear a reduction in the hiss when I audition the plug-in, and I make sure it is active
for the render and not bypassed.
When I compare pre- and post-render files in the same silence secton, I can’t hear a difference in hiss
level. Just to make sure I’m not fooled by the master section, I’m removing the plug when I do the pre/post
comparison, so the master bypass shouldn’t matter (the master level faders are at 0 for the render, and I
confirmed that levels on the pre/post files are nearly identical).
windows 7 64-bit
wavelab 7.11 (build 550), installed as 32-bit app
fwiw, I’ve done other rendering with Slate FG-X and the Crystal Resampler, and those post results seem to
be fine. It just seems like this Sonnox plug will audition with an obvious improvement but I can seem to
get that to render out.
Is there any kind of licensing issue with the Sonnox plugs? seems like if I can insert them and hear their
effect prior to rendering, then that shouldn’t be an issue.
Any help appreciated–this is driving me batty!
