This is why good consoles and good mic preamps have Polarity switches because when it is inverted in the input stage of a preamp its absolutely correct with no discrepancies when its done in the digital domain depending on software/hardware sometimes errors in phase are introduced because the signal is not 100% converted to 180 degrees it might be 179.9 this is called phase error

And your point is? I was saying that people confuse phase with polarity all the time when people are using room mics with a mixer output we are not talking about phase we are talking about polarity. Thats the issue I was talking about how people call a polarity reverse on a preamp a phase reverse that is not correct.
