This paper presents a real-time software of sampling jitter measurement. The software is programed on the MATLAB environment using the data acquisition toolbox to get analog-to-digital converted audio signals in real-time. It can display a jitter waveform and its spectrum. It can also display an amplitude fluctuation waveform and its spectrum, which is often observed as a result of conversion process in a DAC or an ADC. The beneits of the real-time jitter measurement are discussed in terms of the factors truly or not truly affecting jitter and the professional use of the digital audio equipments.
