In the quiz following the segment, it stated that:
Audio sampling is: A digital recording of the sound
During the discussion within the segment, "a Strawberry Fields" sound was brought up. Was not the original Strawberry Fields keyboard intro sound recorded by the Beatles made with a Mellotron which was the first sample playback keyboard? The samples on the Mellotron were all analog tape I believe. This would make the recommended answer to the question above incorrect because audio sampling does not require the recorded sound to be digital.
