hmm... expanding to 24 / 96 CAN make sense, but it mustn´t. the reason for recording with this data rate is simple: more information can be stored at the same time.
remember: CD does take one sample with an information depth of 16 bit 44,100 times a second. if you have more you´ll get nearer to the original. if one can hear it... yeah, that depends on the listener. there are test, where people claim, they can hear the difference, then there are others, who are saying 'one person can´t hear frequenzies over 20,000 Hz'. do a little math, then you can divide 44,100 with 2, then you´ll get the frequenzy response of 22,500 Hz, which is the frequenzy stored on a cd. and now it get´s interesting: the 2,500 Hz are filtered away during playback (because these Hz can cause the speakers for high tones to explode). and this filtering is very cruel to the sound. to get a wonderful frequenzy response flat like ruler, you´ll need a filter, that uses a frequenzy cutoff at 20,000 Hz. theory is, that they can hurt the sound. there is no filter - i repeat - no filter, that can do it without distortion. and now i come to upsampling: IF you do upsampling AND if you have a capable playing device, which really can play 24 / 96, then you CAN get an advantage. and why? because you can move the filtering to a higher frequenzy area (96,000 Hz - cutoff at 48,000) which is at a much higher frequenzy than our ear can possibly hear. a plus: these filters are very flat, they begin filtering aliasing components at 40,000 - they can be much more harmless. some dvd-players have an upsampling function & some newer cd-players also. and it makes sense (at least to me) BUT: you´ll need a very good resampler! and to do an upsample to 96,000 from 44,100 is very very difficult. it requires a lot of numbers crunching & processing power. i don´t believe, that the resampling engine in dbPowerAmp is that good. and remember: you´ll don´t get more information. the example with the upscaled picture is not that bad (althought it omits the point, the a picture is less cruel than sound), because the sound can change - not for the best. the whole big problem is not the recording process. jack renner from TELARC putted it year ago that way: he said, that the only problem is the playback of the digital data. if that could be improved, it would sound much better. -- SonicAdventure ------------------------------------------------------------------------ SonicAdventure's Profile: http://forums.slimdevices.com/member.php?userid=10797 View this thread: http://forums.slimdevices.com/showthread.php?t=33909
