Short Version:
Please add Input Gain & Output Gain to Sibilance (preferably with a linked control.) Sibilance’s settings (and UI display) work a lot better if the volume is a higher level than many people record at.
Details:
I owned Waves Sibilance for years but didn’t have a lot of luck with it. It turns out my vocal levels were too low (for Waves Sibilance.)
Correct me if I’m wrong, but I believe Sibilance was made in the 16-bit audio era where people ran their levels hotter. In the 24-bit era with the added headroom and lower noise floor, people eased back on levels – especially since most analog emulation plugins (including Waves’s) are calibrated to -18db = 0VU.
Either way, this problem would be easily solved with Input Gain + Output Gain knobs – especially with a linked control!!!
Once sibilance gets vocals at a higher level, it’s much easier to read the UI and the various settings become less finicky. It’s actually a fantastic de-esser, but it really needs a healthy gain to be able to dial in the settings to work well.
To use it now I need a gain plugin before and after it. That works fine… but it’s cumbersome.
PS. Some plugin companies are refreshing old products by adding Gain In + Gain Out in the TOP BAR of all their plugins (!). That’s something to consider, as I suspect other plugins may benefit similarly.
