Are the Z1's audio limiter, Microphone Noise Reduction and Microphone Wind analog circuits or digital functions? The manual doesn't state that.

Also, is the Microphone wind function a static high pass (lo cut) filter or a more dynamic "DePopper" function?

I wish the manual would write more about this. I would guess that the Audio Limiter is an analog circuit while the others are digital functions .

I doubt those three functions are digital.

The lo-cut is probably static, which is not that bad if it's well designed. Perhaps some time in the future we can shape what lo-cut filtering we want, considering the audio we are recording.
