yep, key quote from end: A Roku spokesperson on the Web forum stated that though this design decision "makes passing 44.1kHz sources through untouched impossible...we've used a very high quality sample-scaling routine in an effort to make the resampling as good as possible and it should be inaudible." Yes, the SoundBridge does use Analog Devices' respected Blackfin DSP chip, but my experience has been that converting data with a sampling rate of 44.1kHz to one with a 48kHz rate is difficult to do with sufficient precision. It looks as if the Roku's automatic but, in my opinion, unnecessary conversion to 48kHz compromises the audio data's noise floor by introducing mathematical artifacts that I would be surprised wouldn't be audible. Add that corruption of its digital output to its underperforming DAC and analog circuitry, and you can see why I was disappointed by the Roku SoundBridge M1001. -- garym *Location 1:* VB Appliance 6TB (1.10) > LMS 7.7.1 > Transporter, Touch, Boom, Radio w/Battery (all ethernet except Radio) *Location 2:* VB Appliance 3TB (2.0) > LMS 7.7.1 > Touch > Benchmark DAC I, Boom, Radio w/Battery (all ethernet except Radio) *Office:* Win7(64) > LMS 7.7.1 > SqueezePlay Retired: SB3, Duet Receiver Controllers: iPhone (iPeng), iPad (iPengHD & SqueezePad), CONTROLLER, or SqueezePlay 7.7 on Win7(64) laptop Ripping (FLAC) - dbpoweramp, Additional Tagging - mp3tag ------------------------------------------------------------------------ garym's Profile: http://forums.slimdevices.com/member.php?userid=17325 View this thread: http://forums.slimdevices.com/showthread.php?t=94223 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/discuss
