MLP files

MLP files from DVD-Audio I mean.  Is there anything new about how to decode them directly to wav's (either Stereo or DTS etc. in 24 bit)

What is the simplest way to rip them to Stereo FLACS or APE files?

To my knowledge there's no free decoder available.
I guess for now you're screwed if you're not willing to pay big $$$.

As of today, it is not possible to decode the MLP tracks of your  DVD-Audio using open source (or even free) tools. So you need to get  one of the following two tools: 

 
  • The Sonic filters "Sonic HD Demuxer" and "Sonic  Cinemaster@Audio Decoder 4.3.0". They are directshow filters contained  in the package "Sonic.CinePlayer.HD.DVD.Decoder.v4.3.rar".
  • Surcode MLP.
  We can't tell you where to find them, so don't bother asking.

Nero filters are also reported to work

I wish we had a better tool to demux .AOB files. DVDAExplorer_7a.exe only works sometimes.

I think there was a hack for Surcode MLP encoder to make it decode an arbitrary MLP stream. Can't remember if that was for DVD-A MLP or HD-DVD/BD MLP (Dolby TrueHD).

It works for MLP in EVO streams (as reported at doom9.org), but not for raw MLP streams.

It works for raw MLP streams. As reported in the guide that Menno linked (which i wrote), but i learned that part from this forum

I've some hope on a better solution  I will tell you when the time is there ...

There's a program called PPCMripper that can rip MLP to WAV directly from a DVD-A by patching WinDVD. I've used it to rip several DVD-As and it's quite easy to do, compared with the SurCode hack.

The problem is that it supposedly doesn't grab the first few samples from a track, but I haven't noticed any audible difference at all, even on albums with a lot going on musically at track boundaries (Dark Side of the Moon).

I thought that there was some limitation when doing this? That the bit depth was reduced to 16 bit or am i wrong?

Great! I'll finally be able rip those three REM DVD-As that I couldn't before.

The resolution is maintained if you rip with an Audigy sound card. Otherwise, the track is downsampled and dithered.

Just to clarify, the resolution IS maintained when ripping if you don't have an Audigy sound card.  It just won't play in WinDVD in full resolution unless you have the card.

I just wanted to point out that there is a thread on FFmpeg-devel with a patch to decode MLP/TrueHD audio.  It has not yet been included in FFmpeg and is still being revised by the author, Ian Caulfield, but it's still interesting to experiment with in the meantime.

Check out the thread here:

Ok I understand AVS scripts now, but when using the FFmpegSource plugin I get an error like

"Could not load info (FFmpegSource: No video track found)"

Any syntax I'm doing wrong?

Decoding MLP is not the problem. See for example this: http://forum.doom9.org/showthread.php?t=125966
Some more info here: http://avisynth.org/mediawiki/DVDAGuide

Actually, I just purchased and downloaded the latest version of Nero ($79.99) in the hope of ripping SACD and DVD-Audio to the hard drive, but so far no luck -- my laptop (Thinkpad c:a 2003 vintage) keeps telling me there's no CD is in the drive ... well, technically I suppose that's true if SACD / DVD-Audio is seen by the computer as a data disc.  At the same time, my system has no difficulty playing DSD files downloaded from Linn, they sound great although I don't care too much for the music.  Is there a hardware requirement to recognize the SACD or DVD-Audio (obviously video works just fine)?

Well, the thread was revived a little offtopic.
The info in the linked thread is pertinent. It's good to have options!
It could be useful to transcode the files and play them in another format.

thanks kurtnoise, that works!

In foobar it plays, but in the information it reports (my 24-bit MLP file) as 16-bit. However, it does report the 6 channels and 96000 Hz correctly.

I wonder if that's a current problem with FFmpeg MLP decoder and they'll eventually fix it up. Also, I loaded the script into Mplayer/zoomplayer/Kmplayer and they all "played" the file back, but silently. Maybe a downconvert/bitdepth problem?

Yes, I know, it is very useful to transcode them to FLAC, cause you can add meta data.
