Hi!

Foobar2000 0.9.5.1 can't playback this http://www.outburst-audio.com/misc/24-bps.flac file properly. Sound gets distorted heavily.

It was created with Reaper 2.106 http://www.reaper.fm and the updated dll http://landoleet.org/reaper_flac.dll to support latest FLAC 1.2.1 codec.

The thing is:

Foobar2000 can play other 24 bps files properly. This http://koti.mbnet.fi/tritonus/DotNoir/test.flac one for example.

But the Reaper developer has no clue, why the file encoded with Reaper doesn't work properly in Foobar2000. Reaper itself and also the FLAC commandline decoder both can decode it fine.

Any hints?

    It's fixed (or at least an workaround got added) in Foobar2000 0.9.5.2!

    Here a new reply from the foobar2000 developer:

    "Looks like I accidentally left the fix active in 0.9.5.2 release. I still don't believe that this is a legit behavior of FLAC tools and anybody else converting FLAC decoder's output to floating-point values will run into the same problem.
    I hope Josh is looking into this."

    He also uploaded the problematic file again at http://www.hydrogenaudio.org/forums/index.php?s=&showtopic=61792&view=findpost&p=561926

    So it would be nice if that could be fixed in FLAC itself, because the next version of foobar2000 might have this problem again!

    Anyone reading here at all?

    I replied on the HA thread; I don't think it's a libFLAC bug.
