It is well known that timing jitter in digital audio converters can subtly degrade performance. Unfortunately standard audio measurements are not very useful for assessing sensitivity to jitter. Mathematical formulae are derived to relate the modulation artifacts produced by sampling jitter with the jitter amplitude and frequency. The audibility of these modulation artifacts is considered in relation to the jitter spectral content. After examining the main sources of jitter in digital audio systems, measurement techniques appropriate to assessing the sensitivity to each source are described. Results of these measurements are shown for some digital audio products.
