upsample

Add more data points

Upsample is a technical term in digital signal processing and imaging that means to increase the sampling rate or resolution of data.

When you upsample an audio file, you create additional data points between existing samples; when you upsample an image, you increase its pixel count.

The process requires interpolation to estimate the new values.

The software can upsample old recordings to higher bit rates.

Upsampling is the opposite of downsampling.
