A turntable introduces rumble and wow. Rumble is the noise from the turntable and wow is the change in speed from the needle being dragged through the record groove.
is the sound of vinyl due to the physical process of the turntable?
Same here. I do not own a turntable, however, if the sound of vinyl comes from the physical act of the record on the turntable why can't I transfer digital audio or at least emulate that process to digitally recreate that sound? I remember back in the 1970's you had 45rpm records on the back of cereal boxes and they were not vinyl, however they sounded good why can't I do that myself?
