I really don't understand why you want to make dff or DSF or DSDiFF files from the iso to just play in foobar or JRMC. I don't know about the latter, but as foobar plays the iso fine and will load all the tracks into the player then why convert the iso, to whatever, at all?
Just use the iso!
I don't like/trust any photo/music library system and want to keep each track as a separate file so I can control things at the file/directory level. Easier for quickly playing one song or copying to a portable player.
I imagine you want to get JRMC to play these files, but it will not play SACD-R iso?
Doesn't look like it.
Does JRMC play DFFs or any kind of DSD file?
Yes. I'm using the Mac beta and it's fine with DFF and DSF.
If yes, then this is only useful to you IF you have a DSD capable DAC either in your receiver or as an External DAC.
Without a DSD capable DAC you are wasting your time with DFFs, you might just as well convert the iso to flac and play those via JRMC.
Yes and no. I had been converting to 5.1 FLAC files. But that's more work and requires deciding what sample rate to use. It seemed better to just have the .DSF or .DFF files for each track and let the player decode on the fly. Then, when 5.1 DSD DACs cost less than my car, I can switch to that without having to re-split all the ISO files.
However, I do have a question about DSF vs DFF based on lots of experiments this weekend. I have a bunch of SACDs, DVD-As, and some BD-A disks and a nice 5.0 audio system setup. I'm using a Mac Mini driving an Atlona HD570 to extract the audio to analog to my Denon AVR and then using an Outlaw ICBM analog bass management unit. For the foreseeable future, I'll probably be using JRiver to play music and the Atlona doesn't speak DSD, so I'm going to have PCM coming out of the Mac. I had been using sacd_extract to split up the ISOs into tracks and then foobar2000 to convert to multi-channel FLAC files at 96 or 176KHz. However, as I was saying, it seems better to just keep the DSF files from sacd_extract.
I'm confused a bit about the DST compression. I took the ISO of Tubular Bells, which was 2.74GB - which includes both sides of the album in 2.0 and 5.1. After sacd_extract, just side 1 was a 2.75GB file for multi-channel. Is this because the SACD/ISO used DST compression? If so, is there a way for the DSF file to also be compressed? It doesn't seem to matter whether or not I specify --convert-dst. However, if I specify --output-dsdiff, the file is only 884MB! So, does dff keep the compress but dsf doesn't? I wanted to use dsf since I read that dff doesn't support tags. However, if the files are going to be 3 times bigger, I'm going to have to re-think this.
The choices seem to be:
- Just keep the ISO
- Can't deal with individual tracks at the OS level
- Have all areas (2.0, 5.1, etc) present. Could be seen as advantage or disadvantage.
- Can only play with foobar?
- Can only run foobar on PC or Mac under Parallels/WinXP (tried to set up under wine and got nowhere after many hours)
- Keep DFF for each track
- Can play in several programs
- "relatively" small files
- no degradation converting to PCM (at least in the file - playback is a different issue)
- no tagging as far as I've read
- Keep DSF for each track
- Can play in several programs
- huge files! Think this is due to DST compression not being supported
- no degradation converting to PCM (at least in the file - playback is a different issue)
- can tag files
- Keep FLAC files
- Most work
- Most portable / software and hardware support including editors
- Need to choose sample rate and bit depth
- foobar allows choice when converting
- JRiver didn't give choice
- converted to enormous file with sample rate of 352,800! This also choked vlc which thinks it's an error and won't play it.
Does all this look correct? Comments? Suggestions?
Thanks,
David
