oversampling

Multiplying the number of samples in a digital signal by some factor. For example, the early CD players were improved when their digital audio signals were multiplied 8 times before sending them to the digital-to-analog converter (DAC). The digital filters were found to operate more efficiently at higher frequencies. See upsampling.
