If you've not come across the company Soundtoys then you're likely not interested in digital audio processing. I've been using their software for years, most of which has always been a little more quirky and unique then many others. Well version 5 of their collection is now released and I am sincerely recommending all engineers have a serious look - and listen. Having owned half a dozen of their plug-ins my upgrade price was simply insanely low. Check 'em out.
