Hardware and phase shift / rotation

Quick question

An analog hardware synth with a 3-pole hpf, does it also shift the phase around the cutoff frequency like what happens when you apply a non linear phase filter in software?

An analog hardware synth with a 3-pole hpf, does it also shift the phase around the cutoff frequency like what happens when you apply a non linear phase filter in software?

Good question! Lets ask

In analog hardware synthesizers, a 3-pole high-pass filter (HPF) typically operates differently from non-linear phase filters in software. In an analog synth, the phase shift around the cutoff frequency of the HPF is generally more gradual and linear compared to the sharp phase shifts that can occur with certain types of non-linear phase filters in software.

Analog filters, including high-pass filters, introduce phase shifts as a natural consequence of their design. However, the phase shifts in analog filters tend to be smoother and more predictable compared to the sometimes abrupt phase changes that can occur with certain digital filter designs.

That said, the specific characteristics of phase shift in an analog 3-pole high-pass filter will depend on the design of the filter circuitry and components used in the synthesizer. Different analog synthesizers may exhibit slightly different phase shift characteristics even with the same type of filter.

If you're looking for precise control over phase characteristics, especially in the context of non-linear phase effects, digital signal processing (DSP) techniques in software are often more flexible and controllable. However, analog synthesizers offer their own unique sonic characteristics and can produce very pleasing results due to their inherent non-linearities and imperfections.

Sounds plausible
