Which is interesting because 44100Hz was chosen because it had 294*3 samples per 50Hz (half-)frame, 245*3 samples per 60Hz (half-)frame. But of course, with separately coded/packaged video and audio streams (and video being no longer strongly associated with PAL and NTSC formats and resolutions), the interest in clean ratios has declined. -- David Kastrup _______________________________________________ Ardour-Users mailing list [email protected] To unsubscribe or change your mailing preferences please visit: http://lists.ardour.org/listinfo.cgi/ardour-users-ardour.org
