smart:EQ 4

This really is a great product. I use it on practically every channel and don't find any undesirable effects (although my laptop is reasonably powerful).

With a bit of manual adjustment I can dial in the right settings for the sound and the results are always a cleaner, more separated overall mix.

The nearest comparison is with something like Izotope Sculptor (Neutron 3) but, having tried then both, smart Eq 2 is more effective and comes with a wider range of profiles. The biggest criticism I have is that the standard profile seems to apply the same suggested adjustments every time regardless of source! Which is only if limited usefulness. I would expect the standard one to be more flexible, but it's no big deal.

What I would say is that it works best when paired with the smart:comp. They compliment each other to provide a better overall mix.

I picked this up for $70 in the sales and at that price point is a no brainer.
