case for dxd files

[davidebond]

Hi. I have just purchased a cd in dxd format. For sake of precision: 24bit, 352800 Hz sample rate, flac codec. I wrote to label saying that this file was in flac format, but they replied that it was a dxd file
encapsulated in a flac format. Without external dac (Topping dx3), able to read native dsd, Foobar2000 is unable to open the file. What does it mean that a format is inside another one?

Thanks and best,

davide

FLAC is not so much a format although the files are labeled as .FLAC. It is a compression/decompression algorithm for PCM and that DXD file is, in fact, 24/352.8 PCM. The inability of your DAC to support native DSD is irrelevant.

It's DoP but I first time ever heard for such in distributed media.

DoP open Standard | DSD-Guide.com

Still don't understand what you got as flac is PCM only and DSD is 16 bit anyway.

To @Kal Rubinson: my dac Is able, not unable. The laptop is unable. I prefer not to speak of the label, but they do of the utmost quality their aim. If Is DoP Is not dsd. But of It were so, Foobar2000 ought play It. Instead, without dedicated dac It does not work.

Is it a dxd file, pcm audio? Or a dsd version of a 24/352 in a dop wrapper.

It is a 24/352.8 PCM file in a .flac package. DoP is for DSD and not relevant.
I play such files all the time in stereo or multichannel with capable DACs.

Try installing the Foobar "DSD Processor Plug In". I have never found a format Foobar won't play as long as you have the correct plug in installed.

Sure but that won’t help.

I have installed the dsd plugin for Foobar2000 from the package of drives by Topping. It Is a dxd file according to the Expert of the label. I asked him if It makes sense for me purchasing the blu ray pure audio. He replied no and asked what were my tools to listen to music. I added that my dac played dsd native files and he wrote that the files in issue were dxd and not FLAC or PCM. They are dxd files. "The FLAC Is only a transparent container." These are his words.

 

[davidebond]

Excuse me, I meant a package of drivers by Topping.

@davidebond and what did he tell you how to play DoP in PCM (wav) packed in flac? Why didn't idiots use WavePack or something that can carry native DSD and pack (compress) it or at least converted it to 16 bit sqere PCM. DoP is a transport protocol.

 

[davidebond]

I am ignorant on this matter. Excuse me for this thread.

Thanks and best,

I did a quick search regarding it and find only problems regarding it on all leading software player's (Roon, JRiver, Foobar2000...). It's truly an abomination. If I find a way to get it out the flac jacket (container) and transcode it will post back.

 

[davidebond]

Don't worry. Occupy yourself with more important things. I must have misunderstood. The quotation Is literal, but It doesn't matter. There are surely more interesting threads.

Thanks and best,

Davide

@davidebond dear David it's not you plenty of search results and other people with such problems. I really would like to know who came up with idea for such abomination in the first place and it's puzzling enough for me to be interesting.
In short flac is a PCM only and sees the DoP stream as regular 24 bit 352800 Hz wav so it compresses it all the same. So getting it out isn't that hard (just back to wav) but what should I do again with DoP stream output (as it's transport protocol) and how to send it to DAC I have no idea.

"DXD" has nothing to do with DSD. "DXD" is a marketing term for regular PCM at 24/352.8. FLAC is a lossless codec that encodes PCM. So "DXD" can be stored in FLAC format. Your DAC and software must then support 24 bit/352.8 kHz audio, and that's all you need (actually, not).

 

[davidebond]

Honestly It supports more than 30 bits, but It Is another question. I connect the dac to the laptop and foobar2000 Is able to reproduce the files. About dsd or not dsd, in any case my dac Is able to play various types of files from dsd family. I purchased It for this aim. I tested It. And a string "dsd" appears on dac screen.

Hi. I have just purchased a cd in dxd format.

Do you mean you are sold a CD-ROM or CD-R disk with files on it?

How many times do we have to say this?

Nonsense. I can play any of my "DXD" files in stereo or multichannel without problems via JRiver (and, I can assume, the other standard players).
