What is Mix-Minus?
Mix-Minus is an audio routing setup that allows a remote guest to hear everything in the broadcast (host, music) *minus* their own voice, preventing a distracting echo.
Why Mix-Minus Matters for Podcasters
Mix-Minus is a critical concept for anyone doing remote interviews or live radio. If you send the full audio mix back to a guest on Skype or Zoom, they will hear their own voice coming back to them with a slight delay (latency). This makes it nearly impossible to speak (the 'speech jammer' effect). A mix-minus setup creates a specific monitor mix for the guest that includes the host's mic and sound effects but *subtracts* the guest's own input. Modern podcast interfaces like the RODECaster Pro handle this automatically, but traditional mixers require manual cabling to set this up.

Background Noise / Noise Floor
Background noise (also called noise floor) is the unwanted ambient sound present in your recording, such as air conditioning hum, computer fan noise, or room echo. It can distract listeners and make your podcast sound unprofessional.
