Bug with better-than-CD quality FLAC playback

(1/2) > >>

Delta009:
Hi!

Is there anyone here who experience the same problem as me?
I downloaded the latest Nine Inch Nails album ("The Slip") in lossless, better-than-CD-quality, 24-bit 96 kHz FLAC (not the previous CD quality FLAC release of the same album : that one plays fine).

When I try to listen to it on my 80GB Ipod Video, there are weird audio glitches that don't happen when I listen to it with Winamp. These audio glitches seem to happen at very specific places, which made me think that it could be because the files were corrupted, but they play correctly on my computer.

I know that playing 24-bit 96 kHz audio on an iPod is very resource-heavy, but I don't have the same problem when I listen to uncompressed 24-bit 96 kHz WAV.


P.S.: I'm using an old build of Rockbox, because builds newer than r17288-080429 introduced a new bug that caused the iPod to crash when there were more than several thousands files on the hard drive or in the database. I don't know if that bug was fixed, so I don't want to take the chance of updating.

LambdaCalculus:
I have the same album on my 30GB iPod video, and it plays perfectly fine.

Plus, I haven't noticed any bug of the sort that you just described. Update your build.

Delta009:
I just updated. It looks like the new build handles the large number of files I have on my hard drive even better than the old version.

However, besides breaking my themes and running faster, it doesn't solve my playback problem.

The sound is still glitching.

Note that I have the new 24-bit 96 kHz FLAC release of "The Slip", not the previous CD quality 44.1 kHz FLAC.

Llorean:
Well, first off: The iPod isn't capable of outputting at higher than CD-quality anyway, and since our resampler must, by necessity, be fast and low quality to work well on limited hardware (though it could be improved some) your CD-quality ones will actually sound BETTER than these "better" than CD-quality files.

Now on to business: Could you test the files with the latest ffmpeg to see if they experience similar glitches?

Delta009:
1. How do I test them with FFmpeg?
2. Where can I find the latest build of FFmpeg for Windows, not just an old port?

Thank you!
