[QUOTE="artman, post: 1056956058, member: 13962"] Για να μην μπλεχτούμε: Synchronous USB connections use a one way digital connection for music replay and are considered the worst type of connection for audio purposes Adaptive mode is a little smarter. It asesses the amount of data in the frame and adjusts that dac's clock-timing to it. Asynchronous mode is technically most advanced in that it has a feedback loop so that the amount of data in the frame can be controlled. ([URL="http://www.hifi-advice.com/USB-synchronous-asynchronous-info.html"]http://www.hifi-advice.com/USB-synchronous-asynchronous-info.html[/URL]) Άλλη κατάταξη: Isochronous (guaranteed timing) Interrupt (guaranteed data) Bulk (guaranteed data) Control (not used for audio streaming) ([URL="http://www.gspaudio.co.uk/blog/jitter-isochronous-or-asynchronous-dacs_post57.html"]http://www.gspaudio.co.uk/blog/jitter-isochronous-or-asynchronous-dacs_post57.html[/URL]) Επειδή το adaptive isochronous χρησιμοποιείται στην S/PDIF, πιστεύω ότι καλύτερα να μιλάμε για σύγχρονο και ασύγχρονο, αφού το clocking είναι αυτό που μας ενδιαφέρει, παρά η τεχνογνωσία.
