upsampling
This term is primarily used in digital signal processing, audio engineering, and image processing. It describes the technical act of increasing the sample rate, which is often necessary to avoid aliasing during further processing or to match the hardware requirements of a playback device.
While it is often used interchangeably with "interpolation" in casual conversation, upsampling specifically refers to the increase in the number of samples, whereas interpolation is the mathematical method used to fill in the gaps between those samples. In a commercial context, it is frequently associated with "upscaling" in video technology, though upsampling is the more precise technical term for the underlying signal process.
