Jargon 2.0: Double ender

Double ender (n.)

When someone is interviewed on public radio’s “Fresh Air” or similar shows featuring above-average audio quality, the recording you’re hearing is a double-ender. The process involves recording both sides of the conversation with two separate inputs, then editing both parts into a final version. The result is eliminating the phone-call quality one would have if both speakers were recorded from one phone input. They also call this “tape sync” or “simul-rec.”
