With the iFi Nano iDSD I need to enable DoPE in JRiver, but that's still DSD transferred in PCM frames, not a standard PCM file which do not contain DSD at all.
So it depends on the DAC used, but the files are always the same DSFs and DSD streamed should be the same.
I don't have problems too streaming large files to iPad/iPhone using DoP ALAC or DSFs, but only when JRiver converts those on-the-fly to normal PCM.
How do you convert DSF to DoP ALAC in JRiver? In my case it hangs if I check DSP settings to convert to DSD in DoP format ALAC. So now I need to use a trick in Foobar2000 to have DoP FLAC and then convert again to DoP ALAC, but it's time consuming!
P.S. I've PMd seeteeyou to ask for that traslation too, let's see if we can sort it out soon.
I did some more detailed test to understand what JRiver tries to do and seeing your questions, I think there are some misconception/misunderstandings.
Good, this is the way to clear some of those confusing stuff out.
About the DoP ALAC, it is ONLY for Lacie to stream wireless to iPhone 8player. Seagate Wireless Plus or Lacie can only stream ALAC DoP. Or DSD contain in ALAC formatted files.
When 8player picks the ALAC Files out, the DAC will see it and decodes it automatically to DSD.
I use Jriver to CONVERT DSD/DFF, hmm.. no CONVERT, but CONTAIN the DSD to a ALAC Container which conforms with DoP. Jriver does it well in this. Most other software does FLAC based DoP. Unfortunately, 8player DO NOT decode the FLAC based DoP from Lacie/Seagate Wireless plus correctly as compared with ALAC. This is in agreement with a forummer's initial findings on Seagate Wireless Plus.
Another few things I noticed. In my Mac version, even in DSD Studio -> Output format, if you set everything off, it does not mean JRiver do not use DoP... Rude Findlings.
I found out that it is still in DoP output from JRiver when playing DSD files (raw). So when JRiver plays a DSD files, as you have said, it will do it in DoP encoding on demand.
I found this because I was testing 2 DACs. Korg 100m and Hugo. Hugo has no issue playing the DoP and shoes it is DSD format, but Korg refuses.
I know Korg do not support DoP.
After looking through clearly, under Tools -> Option -> Audio, there is a Bitstream section.
It was set to DSD.
When I do a playback of a DSD file, I check using the DSD Studio tab, at the bottom, it plays the source as DOP!
I turn the bitstream to OFF. restart the JRiver.
Now strangely, my Korg plays perfectly, since it streams RAW DSD now.
Check on the DSD Studio, it was looking at 384khz at 64bit! My Hugo is looking at t file at DXD format. Even though it is not bitstream but file is played raw through USB.
I might be wrong on this, but reading the initial technical stuff in JRiver, THIS IS the preferred way as the headroom created will be good for the format to work in the DAC. Of course, provided the DAC supports it. That was why when played raw, my Korg plays at DSD64, but HUGO was able to handle extremely high bit rates, it just give it all its got.
I did not have a chance to test the diff in the sound for both, but this is an interesting finding from JRiver.
So, to help clear the initial confusion, JRiver is a tool I use initially to create DoP ALAC container files from raw DSD for the file to be able to be streamed from Seagate WP/Lacie Fuel to 8player.
I did not use JRiver as DLNA since my aim is to get Lacie Fuel to stream DSD format to my HUGO via iPhone.
I have yet to test more detail on the DLNA function, but have done so for the USB direct connect for DACs.
JRiver is a power software, but a lot needs to be clarified when setting it up for us. And again, it is not stable. It crashes quite frequently.
How to convert:
- in Player Tab -> DSD Studio, ensure you choose the right DoP. If it is DSD 64, chose single DoP, if it is 128, chose 2x DoP.
- Select the DSD files
- Right click, choose convert format.
- A small window will appear on the lower left of the JRiver left column.
- choose format to ALAC.
- Click on Options to ensure you have the right destination set.
- Click convert
FooBar does not help at all. It is terribly difficult to convert to ALAC for Foobar. And you are right, -> FLAC than to ALAC.... doesn't make sense.
Initially, I do have problems converting in Jriver. After upgrading JRiver to the latest, it worked well. Again, there are some crashes but was able to manage it.
Hope the above helps to clarify some points.
