Countable noun

Definition

n. a piece of software or hardware that changes information into a different format. You use it to make files smaller or to keep data safe.

n. a device, circuit, or software program that converts information from one format or code into another, often for the purposes of compression or encryption.

Examples

“You need a video encoder to stream your gameplay online.”

“The software includes a high-quality audio encoder that reduces file size without losing much sound detail.”

“Modern digital broadcasting relies on a sophisticated hardware encoder to process raw video signals into a compressed stream suitable for satellite transmission.”

Real-World Examples

“Open decoders ignore that field, so ffmpeg and Cavern play the file fine. Dolby-certified hardware checks it, finds no valid signature, and falls back to plain surround sound. The audio coding is solvable in the open. Playback stays gated behind a signature only Dolby’s licensed encoders can produce.”

“Meta describes its method as a three-part system trained to compress audio to a desired target size. First, the encoder transforms uncompressed data into a lower frame rate “latent space” representation.”
Ars Technica 1 Nov 2022
“The 14.2 update includes GPU-accelerated encoding using Nvidia’s hardware encoder for the company’s Quadro and GeForce graphics cards, with the promise that video editors will be able to export high-resolution videos up to 5 times faster than by just using the CPU.”
The Verge 18 May 2020
“The encoder module E takes raw observations as input, and outputs a gridded estimate of the initial state of each variable for the processor module.”
