[Re: Audacity 2.1.0 & 2.1.1 running on Windows Vista].

Spitfish problem in 2.1.0 & 2.1.1 : the previewed effect is stronger than that which is subsequently applied.

When using Spitfish the de-essing effect is much stronger in the preview than when it is applied to the audio.

Hypothesis : the real-time preview is unintentionally applying the effect twice , ( i.e. an unintentional iteration) , but when the effect is applied to the audio it’s only applied the once.
