IPOD Touch 2G - Apple Lossless

I've read that if the upsampling is done at a good quality (which SSRC should be)- then upsampling from 44khz to 48khz, and then encoding at that - gives the DAC more of a chance of producing a faithful analogue reproduction ?

any benefit ? or snakeoil ?

can all be done in one step in DBpoweramp - so takes no extra time or effort

I've heard its a no-no with MP3 as Lame is optimised for 44khz ?

thanks, MArk.

I think short jumps like that are more likely to harm than help the sound.

If you were going 44.1khz -> 88.2khz that would lower the noise floor of the DAC (and i think this is how that kenwood keg thing does it's thing), but a jump of 3.9khz is just going to increase the distortion in the signal.

Oh, and i sincerely doubt that any time domain encoder (including all MP3 encoders) are "optimized" for one sample rate or other.

I am with 'ericj'.
Certainly think you would be better off with "true" lossless files, than files gone through up-sampling before encoding.
