    Hello everybody
    I was wondering How can i convert a (.DFF) 5.1 to another lossless format with the same amount of channels (((LOSSLESSLY))) ?

    I tried Foobar (with the SACD components) and Foobar plays the files perfectly . However if I try to convert the files to a lossless format in Foobar i(right click > Convert > quick convert > *lossless format*) but foobar gives the warning "Foobar2000 does not support DSD pass-through; the conversion will NOT be lossless".

    I tried to import the .dff file into audacity but it was just 6 tracks of white noise (static noise)

    Use FFmpeg.

    ffmpeg -i input.dff -c:a pcm_s24le -ar 96000 -rf64 auto output.wav

    Have you tried "Xrecode"?

    XRECODE3

    I don't know if it's available as trialware, but it's the only tool I've found that will play with DSD files without resorting to DSD-over-PCM (like JRiver does witho0ut telling you. Whether it supports 5.1 output is something I have no idea abt.

    I do. It sure does! I use it a lot.

    You can't, the conversion from dsf/dsd to pcm is always going to be lossy

    Technically, you are correct.

    BTW, I dispute your statement that it "will play with DSD files without resorting to DSD-over-PCM (like JRiver does witho0ut telling you." First, XRECODE3 doesn't play anything. It is a conversion/extraction/recoding program. Second, Jriver player DSD just fine without resorting to DoP if you have the proper equiment.

    Not meaning to sound defensive , but by "play with DSD files", I meant manipulation without degradation, not playback. I needed to cut up a DSD rip of a vinyl and XRecode did it. I don't know about playback, but JRiver's secret DoP sauce IS involved in any kind of conversion/slicing/dicing. Maybe that's changed with recent versions. Had to do a lot of forum-digging to find that out at the time.

    Practically, you're wrong.

    OK. I missed the "with."
    First, I DoP or DSD-over-PCM is not a conversion but a strategy for transmitting DSD over S/PDIF and, fwiw, does not convert the DSD to PCM but simply packages the data so it will pass to suitable DACs. It is not involved at all in "any kind of conversion/slicing/dicing." I play DSD at all data rates and resolutions directly through JRiver daily without "any kind of conversion/slicing/dicing."
    Second, if there is a reason to do "any kind of conversion/slicing/dicing," that has nothing to do with DoP but with Jriver's DSP operations which are pretty explicit.
    Third, yes, when Jriver converts from one form of DSD to another (such as up-sampling or down-sampling), it does so through a PCM intermediary. That is fairly well-known and not denied by the Jriver folks.
    Fourth, if you choose to do any EQ or processing, it will be necessary to convert DSD to PCM but that is not unique to Jriver. I do not know of any alternative and, certainly, not one outside of a studio.

    And you, too, are correct.
    The converted stream is not the same data but it is the equivalent. You know it is not the same because converting it back to DSD will not result in an identical bitstream to the original.

    Whenever something doesn't sound right, I just turn it up.

    If that works for you, fine.
