Resample

The process of sampling an already digital signal again. Normally once a signal is in digital form all sorts of things can be done to it with DSP. But in some situations it is desirable to sample the signal again. For example, in some hardware based sampling instruments there is a limited amount of DSP available. Users will sometimes apply a host of effects to that signal (possibly even analog effects) and resample it with them so the new sample has the desired sound while freeing up DSP to do other things. It’s also common to take a series of audio bites (like an arranged drum groove) and resample it all as one performance that can be triggered. Some devices also use resampling to change the sample rate, rather than use a sample rate conversion algorithm.
