For each voice, polarity only needs to be set once for each mic source. For crystal, ceramic, and dynamic mics, that can usually be accomplished by inverting the polarity at the mic element. Most folks who take AM polarity seriously are also using some other intermediate audio processing device with balanced input/output terminations. In that case, inverting polarity is as easy as flipping conductors on one balanced audio pair. For tiny electret mics without any additional processing, the problem becomes a bit more complex to resolve but then, I don't know of many folks using electrets on AM.
If a phase scrambler were part of the K3's DSP, any thought as to how much DSP resource utilization is required?
