All my music files are purchased from HDTracks.com 24bit/192khz flac. Cost me $20 and up for an album. I use DBpoweramp program on my Windows7 home computer to reformat the files to ALAC and AIC lossless. First I tried ALAC, iTunes would not allow me to save them to the iPod Classic 160GB. Then I tried AIC at 24bit 44.1hz. That worked. Then I tried AIC 24bit 48hz and my iTunes let me transfer them to the iPod Classic but now no songs in any format will play on the iPod Classic. If I let the iPod Classic auto transfer the files to AAC 256kbs then I that iPod will play back those files. But that sounds aweful, Sounds like MP3's playing. I paid good money for lossless flac music from HDTracks.com and I want this iPod Classic to play back the best format it possibly can on my car stereo which is the new Sony 701HD with the iPod builtin dedicated i-cable.

 

Can someone please let me what is the highest resolution and format that this iPod Classic 160gb device can playback and which Bit rate and frequency? I turned off the Auto transfer to AAC option in the new iTunes program.

iPod classic, Windows 7, Sony 701HD car receiver

    I hope you get to read this and that you haven't sold your iPod (I do not work for Apple, btw). Yes, the iPod Classic does play 24 bit files. However, the khz has to be converted down to 48khz and it has to be in the ALAC (Apple Lossless Audio Encoder) format. I've purchased stuff from HDTracks and it plays on my iPod, again, as 24bit/48k ALAC. I've read on other forums that if you have Rockbox on your iPod, it will play up to 192khz, but others say that the iPod downsamples it when you play the files... (I wouldn't know, I don't have Rockbox on my iPod).

     

    I hope this answers your questions...

    Thanks a lot stylinIp38 for your efforts! This is a definitive answer to ongoing myths regarding HD audio on Apple's ipod devices.

     

    There is just one question left to be answered, even if TRosado indicates that it would be possible: is the iPod classic (7th gen) able not to only play but to really *render* 24 bit ALAC files? If the DAC hardware incorporated into the iPod is only 16bits they would just throw away the 8 "useless" least significant bits. On the crappy Apple earphone you'd rather hear this...

    I think the iPod will also play 24/44.1 ALAC, so all multiples of that sample rate should probably be donwnconverted to that, right?  For example, 88.2, 176.4KHz.  Others should be downconverted to 48KHz.  I used XLD on my Mac to do that.
