W1 Limiter is a clone of Waves L1, with identical output. Waves L1 famous limiter (and thus W1 - for compatibility reasons) uses three times longer actual release time than standard RT60 metric. This means that if you set 50ms release in the limiter, it will actually yield with 150ms standard RT60 release time.

W1 Limiter has been updated to include both at 32-bit and 64-bit version in the download file.
