Raises the sampling rate of digital data providing a smoother signal curve, but does not provide enhanced detail or resolution of the output. Oversampling takes two successive (one after the other) samples of the digital data and then splices in additional samples that are interpolated to fall between the two, true originals. hink of taking a one-foot tall block and putting it in series with a block two feet tall – these two blocks are the original samples. Oversampling would then add in blocks that are one foot two inches, one foot four inches, one foot six inches, one foot eight inches, and one foot ten inches to create a smoother curve. That smoother curve can then be used to more easily create an analog waveform, and it helps to create a signal that is less bumpy than the original digital data. However, the additional samples are merely educated guesses and do not add quality to a recording that is not there. Oversampling helps digital-to-analog converters to operate smoother but it does not compensate for a digital signal with a true higher sampling rate and/or greater word length in bits.
