What is Double-Ender?
A double-ender is a remote recording method where each participant records their own audio locally on their computer. The files are later combined, ensuring high quality regardless of internet connection.
Why Double-Ender Matters for Podcasters
In the age of remote podcasting, the 'double-ender' is the gold standard for quality. If you record a Skype or Zoom call directly, the audio is compressed and subject to internet glitches (robotic voices, dropouts). In a double-ender, the Guest and the Host both run a recording application on their own computers (or use a platform like SquadCast or Riverside that does this automatically). Because the audio is recorded locally to the hard drive, it captures full studio quality. After the interview, the guest sends their file to the host, who syncs the two perfect tracks together. This eliminates the 'Zoom sound' completely.
