Jitter Simulation in High Resolution Digital Audio

Authors: Hawksford, Malcolm J.

Abstract

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.
