In Reply to: Vinyl to iPod- my experience- long posted by Bill Brown on October 27, 2004 at 13:02:58:
Bill,I think it has too do with the dac in the iPod. I think it is only capable of 48/16, I am looking for my schematics too see if I can find that out... but my office is a mess.
AHHHH Oh well... each of the last few iPods have had different dacs but I think the top output is 48/16. Though I have not tried to convert anything to 48/16 it might be worth a try.
Follow Ups:
I suspected that was the case. The iPod (hard drive) seems to store/handle the files fine, just not replay them via the DACs.Now, if I could just figure out why my 24/88 AIFF files all store in iTunes as 24 bit/ 65.535Khz. Any ideas based on your advanced technical knowledge/understanding?
Thanks,
Bill,Bill as a programmer I can only assume that it is an unsigned integter of 16 bit quantity and therefore the maximum it will take would be 65535.
Seems unlikely though as I did some work with iTunes and Firewire dac and there it was 2 channel and 24/192 but I never actually look at the data going out much as the circuit that Apple/Oxford Semiconductor was pushing was complicated and high in jitter.
I know Atkinson is pushing higher rates in some other applications, why not ask him.
