Re: [SurroundSound] Re: SACD ripping offer (Australia)

Because of my hardware set-up, I can't play multi-channel FLACs, so have to convert to DTS FLACs. 

I'm curios; you can play multi-channel DST encode file, but not a multi-channel FLAC file?

If you have a MCH receiver that has no HDMI, all you need is a DST or AC3 driver  - eg a bit of SW that encodes MCH PCM in real-time and passes it to S/PDIF. Even Windows has this feature since 7, and so does ffmpeg on windows. On Linux, there are Alsa output drivers for both DST and AC3. I'm not an OSX guy, but I'm sure at least ffmpeg was ported to OSX. I cannot see another reason to need DST (file) format at all ... (?)

Far too often in this community I see people spending a lot of time and energy down-converting for one perceived reason or the other. Once upon the time, there might be a reason or two for it, especially the CPU limitations.

A previous email on this list was talking about DST to PCM conversion...

Why?

We have CPUs more then powerful enough (I even got my 2-core Atom based mobo to play multi-channel DST (T! Compressed!) to PCM DAC in real time - directly from SACD ISO) and there are some very high quality real-time resamplers out there (libsamplerate, soxr) and several players that read SACD ISOs directly. And there are severl players that do all this for you on the press of the button: Foobar, jRiver, MPD...

I suggest to re-evaluate the need to extract anything from ISOs (including DVD-As) and convert any DSD/DST to PCM.

BTW, this might be a good opportunity to make more people aware that MPD can also read SACD/DVDA ISOs, and play DSD and DST files (all to PCM DoP, or native DSD with configurable resampling quality) - Thanks to briliant work Maxim Anisiutkin

It now even has a compatibility with Foobar XML ISO tag files, so if you tagged your ISOs in this way in FooBar, you wont loose any manually entered data.

If I missed a good reason to spend days triplication everything - including your hard disc size, I'd be interested to know :)
