Yes, they are by Antress, but I always call them the Modern plugin set.
I have a few myself and put them on the VST list in the 'known to work' thread.

That said, PGMusic Dynamics plugin offers both needed FX in one.

The top half is an expander (will reduce noise during quiet/silent parts)
the bottom half is a compressor (to make everything louder).

It may take a bit of fiddling with dials to learn it, but worth learning.

For anything like this I usually turn to Ozone, but it's not free.

DigitalFishPhones makes a nice little collection of FX - compressor, noise reduction, and de-esser for free also (the Fish Fillets). These are pretty simple if a beginner at using these types of FX, but also very effective.
