DR4 eh? That's positively dynamic compared to Iggy and his DR0 :-). Here's what I see with that Two Door Cinema Club track - Original: 14780 -3dB cut for headroom (figure from your comments that was all that was needed): 14781 ASRC upsample to 192kHz: 14782 Peaks now go from -3dB to -1.47dB. Headroom needed for this track: 1.53dB using the dBPowerAmp upsampler - pretty close to your +1.4dB. I want to see a *real* piece of music (not some synthetic test tone) that needs +5dB headroom (not to mention +11dB as in one of the other threads). I'm thinking a 3dB headroom (1/2-bit) should be enough for upsampling... +-------------------------------------------------------------------+ |Filename: ASRC.jpg | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=14782| +-------------------------------------------------------------------+ ------------------------------------------------------------------------ Archimago's Profile: http://forums.slimdevices.com/member.php?userid=2207 View this thread: http://forums.slimdevices.com/showthread.php?t=98706 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
