I am getting confused with different peoples' uses of the term 'sample' or 'sampling'. Some people using drum beat programs like fruity loops, generate a drum beat sequence and then take a subset (sample) of the loop's playing and use that 'sample'. That use makes straight forward sense.
People doing foley artist stuff for movies, record a glass breaking to resuse it in place of another sound in a video, and refer to that 'sample'; is this correct usage?
Then, some people wanting to make VSI from a single sample (sound clip) of a sound of a siren or horn to play over a range of notes/pitches, refer to their 'sample' when using it in cubase; is this also correct usage?
What should a 'sample' or 'sampling' really refer too?
