How are you doing the resampling? Is it software you have written? If you are using hardware implementation, such as an ASRC, there is not much difference between integer and non-integer rate conversion, at least, with respect to the algorithm used. -- ezkcdude DIY projects page: http://www.ezdiyaudio.com System: SB3->EZDAC->MIT Terminator 2 interconnects->Endler Audio 24-step Attenuators (RCA-direct)->Parasound Halo A23 125W/ch amplifier->Speltz anti-cables->DIY 2-ways + Dayton Titanic 10" subwoofer He's not hi-fi, he's my stereo. ------------------------------------------------------------------------ ezkcdude's Profile: http://forums.slimdevices.com/member.php?userid=2545 View this thread: http://forums.slimdevices.com/showthread.php?t=32958 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
