Title: DSD to PCM 88.2/24 (FLAC or ALAC)
Post by: john greenwood on February 01, 2014, 07:01:00 pm
I miss instruction manuals.  I tended to read them.

Just got JRiver 19 yesterday

I've read the Wiki on converting DSD to PCM .  I get to the step of Applying DSP, and I click on DSP settings. The Wiki says that I am supposed to select my choice (88,200hz).   I do.  I also check Output Format in the upper left art of the box. However, I see no OK button, and when I close and open the box, it does not appear as if the 88,200 hz selection is saved.

I have tried this with both FLAC and ALAC as the target formats.

Also if I want to have the option of volume leveling on playback to I check it here?

Never mind - figured out what I was doing wrong.

Agreed. That dialog box is a funny old thing  ;)

Download as DSD and play as PCM.

There's no reason to convert.

JRiver is good at this, but other programs can do it as well. You can also convert offline with JRiver, but again, there's no reason.

There's a perfectly good reason to convert if I am playing through a Squeezebox, and I do not have a DAC that supports DOP.

I'm trying to figure this out as well.. How do I take a DSD download and play it through my "PCM only" dac.  There's some sort of conversion step I'm missing.

Check MC's DSP Studio / Output Settings.

I don't see anything that offers DSD to PCM conversion... Only thing I see is output encoding and sample rate.  My sample rates are set properly and my output encoding is set to none because all the options say it's only for "DSD equipped"Dacs... which mine isn't.

According to this it outputs to PCM by default.  On the fly conversion would not work for my current configuration where I will be using Squeezeboxes and the Logitech Media Server.

DSD is converted to PCM by default, and follows the "Greater than 192,000 Hz" section in DSP Studio's Output Format settings. (as DSD is converted to 352.8kHz PCM)

And, in fact, all the music files currently available that are "greater than 192,000 Hz" are DSD-related (DSD64, DSD128 and DXD) - so if one does not have a DAC that plays back DSD, one should set "greater than 192,000 Hz" to output at 176,400 hz (if one has a 24/192 DAC) or 88,200 hz (if one has a 24/96 DAC), so that the conversion can work by "halving" the rate (instead of doing a complicated conversion).

There are no 384,000 hz tracks out there, so it is safe to do it this way.

It works but it is implicit, or hidden. Would be better if the label clearly stated that "Greater than 192.000Hz" includes DSD.
