A local recording eliminates all the fail points and fidelity degrading processes by writing all your 0's and 1's directly to your computer without any consideration of WiFi strength, bandwidth availability, or whatever noises your cohost is making on the other end. If you're using a platform like Zoom or Skype to record your podcast, keep doing what you're doing, just consider adding a local recording via your DAW of choice, Quicktime, or an interface with onboard recoding options. You'll immediately see a dramatic improvement in your audio quality.
