-Although DirectSound does not claim to be "bit-perfect" since it takes the integer audio --> converts to 32-bit float --> dithered back to 16/24-bit and sent to the DAC through Windows Mixer at a specific sample rate (set in your Control Panel for the sound device), it looks like it is able to do this with a single audio stream of the same sample rate without significant deterioration in the output in the 24-bit domain (remember the DMAC Test is 24-bit audio) - not exactly rocket science so this is to be expected. I believe many folks feel the quality of the Windows Mixer has improved over the years.-
Hi Archimago A lot of hard work and results on your blog, which I enjoyed reading. I would like to say that, for 'audiophile' use, the 'mixer' in Windows XP was the pinnacle, as DirectSound is bitperfect (if the hardware and audio driver allows). In Vista and Win 7 (I have not tested Win 8), not only is this impossible to achieve with DirectSound, but the mixer permanently engages in more than you describe, the results of which do not look pretty on a proper suite of tests. ff. ------------------------------------------------------------------------ flimflam's Profile: http://forums.slimdevices.com/member.php?userid=56891 View this thread: http://forums.slimdevices.com/showthread.php?t=98933 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
