![]() ![]() Therefore it is preferable to choose the device with the ADC as the clock source for the whole system. The DAC will eliminate any jitter generated by processing or transmission. If a signal had been digitised by a good ADC with an accurate clock, then any jitter introduced during processing or transmission won't be audible providing the systems DAC operates without jitter and is synchronised to the same clock source as the ADC. ![]() It is important to understand that "jitter" and "drift" only affect audio quality if they occur during analogue/digital and/or digital/analogue conversion in a ADC or DAC. NOTE: You may also wish to read Connectors in the recording studio to understand a little more about the variety and uses of digital audio connection technologies. Here are some of the devices that may be connected together in a digital audio system. If the signals and devices are not synchronised, audible clicks and pops will result every time a receiving device fails to correctly anticipate the arrival of samples in an incoming signal. Therefore, their sample rates will need to be identical and they will need to meet "in sync". Like 2 cogs in a mechanical system, they must mesh. ![]() Unlike analogue audio connections, when multiple digital audio signals meet or move together between devices (such as a digital mixer and a DAW-digital audio workstation) they must be synchronised by a common clock. ![]()
