I’m happy to announce the updates of all OS X plugins based on the Audio Toolkit. They are available on OS X (min. 10.11) in AU, VST2 and VST3 formats.
When I first read about transient shaper, I was like “what’s the difference with a compressor? Is there one?”. And I tried to see how to get these transient without relying on the transient energy, with a relative power (ratio between the instant power and the mean power) filter, or its derivative, but nothing worked. Until someone explained that the gain was driven by the difference between a fast attack filtered power and a slower one. So here it goes.
