To reconstruct an audio waveform samples must be located precisely in time. Practical systems have sources of jitter described by both correlated and uncorrelated elements that result in low-level distortion. However, less well known is how different forms of jitter distort an audio signal. Jitter theory is developed to produce a simulator to enable jitter induced distortion to be determined. Distortion spectra can then be observed and time domain distortion auditioned. Jitter induced distortion is compared to a range of errors, including DAC errors and incorrect use of dither. System architectures studied include LPCM with up-sampling and noise shaping and SDM.
