we are using a lot of nuendo plugins for our work and they are great.
postfilter is one of them.
the issue is that spectrum view is so small that only realistic thing you can do is LO/HI pass.
- ability to ZOOM to certain frequencies (ie, 8-12 k) so we can destroy that 10k buzz easy.
2.some sort of learn function with basic algorithm (lo freq hum, hi freq buzz etc…)
really a great tool, shame it is so…forgotten from steinberg
