The basis of relatively noisefree and distortionfree. Before the samples are taken, the audio goes through an antialiasing filter to remove any frequencies above the nyquist limit, or half the sampling rate, which could potentially cause aliasing distortion. To do this, it samples, or digitizes, the sound by taking precise measurements of the wave at frequent intervals.
