I'm mastering some 96KHz material that has a nasty hum running around 32KHz, which mostly I can only hear when playing back at half speed or scrubbing. As a last step of the mastering process, I'm doing some light denoising using Izotope RX2. If I tweak the envelope for RX's Denoiser, I can pull down the offending frequency a bit, but I'd prefer to notch it out with a sharp EQ.
The problem I'm running into is that my plugins only allow a maximum frequency setting of around 21 KHz. Does anyone have any suggestions for an EQ that can pull down frequencies above the human hearing spectrum or a workaround?
This obviously isn't a major problem, but now that I've realized the limitation, I'm curious if there's an easy solution.
