COMPUTER AUDIO - WHY DOES A SIMPLE PRINTER USB CABLE NOT CUT IT FOR HIGH QUALITY COMPUTER-BASED AUDIO? ANSWER: There is a fundamental difference between the transfer of computer data and digital audio signals. Computers are able to transfer digital data without loss, because the data moves in the robust form of blocks, which do not depend on specific timing between the sending and receiving devices. However, digital audio signals are continuous streams of data, which are quite fragile, since the digital processor must remain perfectly locked onto the timing of the signal to avoid data losses. The limitations of digital audio processors and cables create timing errors known as jitter, which remove portions of the audio signal and replace them with noise and distortion. Cables tend to round off the square waveforms of the signal, making them less clear to the processor, thus increasing jitter. This rounding effect varies greatly among cables and a truly superior digital audio cable can make great improvements in sound quality. SOURCE: wireworldcable/categories/usb_cables.html
