wavpack files are skipping on iPod 5.5g
« on: December 10, 2010, 04:47:48 PM »
Wavpack files are skipping when I try and play them.. any ideas of why that would be? song will play for 2 secs.. pause.. play again.. pause.

could the bitrate be too high?

Bitrate shouldn't matter, although if you have an extremely high sample rate that might be a problem.

Whats the exact bitrate, sample rate, etc?

bit rate is 5205 Kbps
192k sample rate
48bit
file size 744.37 mb (it's an entire side of an album)

You'll need something closer to a desktop PC worth of CPU power to play files with such an absurd sampling/bit rate. 

Also FWIW I don't think that file is really 48 bit, but if it is you should know its not actually physically possible to create audio with 48 bit depth, so who ever encoded that file set something incorrectly.  Assuming you want this to be lossless, you may want to find the original source material and reencode the file properly.  If the person encoding the file altered the bit/sampling rates its almost certainly not a lossless encode.

the wavpack was made from a 192kps master.. I double checked the file is 48bit. btw, I didn't make it. Just trying to listen to it..

thanks so much for the quick reply

Given the file's bitrate its not really 48 bit, probably someone just took a 24 bit master and "improved" it to 48 bit.  If you want to listen to it, you'll need to fix the file.  For best quality in rockbox, you will want to use 44.1khz with either 16 or 24 bits.

First decode the file to wav on your PC.  Then resample the wav and reencode.  FWIW on linux I recommend Sox, on Windows i recommend either sox or foobar2000 for resampling.  Both are extremely good for this kind of processing.
