Poor resampling algorithms, whether upsampling or downsampling, can introduce artifacts that are clearly audible during playback. A typical low-quality, but extremely fast algorithm will be based on linear interpolation. High-quality oversampling algorithms use more processor time because they require conversion to the frequency domain.

A practical and well-known example results from the fact that professional audio equipment uses a sampling rate of 48 kHz, but consumer audio equipment uses a rate of 44.1 kHz. Therefore, to transfer music from a professional recording to a CD, the sampling rate must be changed by a factor of: (44100 / 48000) = (441 / 480) = (147 / 160)

Resampling or Sample Rate Conversion is required when one wants to convert a digital audio file (i.e. an analog audio signal that has already been digitized) from a given sample rate into a different sample rate (resolution can stay the same or change). Upsampling (aka interpolation) is the process of converting from a lower to higher sample rate (e.g. from 44.1 kHz to 48 kHz); …

Shannon’s sampling theorem says it is possible to restore an audio signal exactly from its samples, it makes sense that the best digital audio interpolators would be based on that theory. Such “ideal” interpolation is called bandlimited interpolation. A bandlimited interpolation algorithm designed along these lines is described in the theory
