> There are some software-tools for ripping DVD-audio, but I have no > experience in using them so I cannot give you any advice. By which I think we mean that there are tools for "ripping the audio from a DVD-Video disc", rather than "ripping the audio from a DVD-Audio disc", which is intended to be extremely difficult. The Imtoo 'DVD Audio Ripper' (http://www.imtoo.com/dvd-audio-ripper.html) is a cheap way of doing this - I have not used this specific tool but the other Imtoo tools I've tried seem to work as advertised. The 'DVD Audio Ripper' is apparently able to rip AC3 streams and LPCM. Surcode, from Minnetonka Audio Software (www.surcode.com) is an extremely good range of software (as are all Minnetonka's products) but not cheap, and aimed at the professional production market. Slimserver6/SB2 does maintain bit-accuracy end to end, so you can save any surround-encoded stream (AC3, DTS, etc) with a lossless method (I use FLAC but WAV obviously works) that you can decode at the other end - this would include an MLP stream, were you able to lay your hands on one and had an accessible decoder for it at the other end. --Richard E -- relen ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

I then used vobedit to demux the ac3 stream. So I'm left with the dolby digital audio in an ac3 file. Do I just rename this to a .wav extension and it will playback on the SB2 provided I've got the optical out plugged into a Dolby Digital receiver? Or do I need to do anything else? Will it even play at all on an SB2? Thanks -- chrisal ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

The reason it works with "*** wav" files is that these are ripped in such a way that they can just be played over s/pdif without the transport needing to know about data the format. To convert a raw ac3 file into an ac3 wav, you would need some tool to add zero padding to the stream to bring it up to 1.4 Mbps for transmission over the s/pdif. I don't know of a tool that does this. If somebody were to make one we could add support for ac3 using convert.conf. -- seanadams ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

Right Then - I had to go round the houses but I've now got my Dolby Digital 5.1 copy of With Teeth by the Nine Inch Nails playing in surround sound on the squeezebox2. Here's how:- I used this tool to extract the 6 seperate wav files directly off the DVD AC3 stream: http://www.download.com/3001-2140_4-10425021.html?idl=n Then I used surcode DTS-CD to create a DTS encoded wav file from the six seperate wav files. Then you can simply play this using the squeezebox 2 and provided the optical output is connected to a DTS receiver/amp then hey presto - surround sound playback! Awesome! I know this has been covered in a few threads before but I've not seen it explained step by step in the forums. Does anyone know if it is possible to make and plaback a native Dolby Digital 5.1 wav file in this way or is this the only method of surround sound playback on the SB2? Even if this is the only way I'm still chuffed that I can rip those 5.1 albums in this way... The next step is to make a cue sheet for the wav file so I can display the track names etc -- chrisal ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

Ok - I've done some more testing with surcode DTS-CD and DVD audio extractor. It seems to work best if you create one large file of the whole disc otherwise gapless playback doesn't seem to work. Because it's a WAV file you can compress it using flac and add metadata such as a cuesheet of you want - I'm not sure if this works with the SB2 though as I didn't test. I downloaded a cuesheet for the album in question and rescanned. Then, by browsing the music folder I can select individual tracks from the cuesheet and also get full track info on playback. I'll try embedding a cuesheet tonight to see of that makes it accessable from artists/albums etc. I had a quick look at AC32WAV but this seemed to create a wav file almost exactly the same size as the .ac3 file and the squeezebox wouldn't play it still - any ideas? -- chrisal ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss

I've just googled for AC32WAV (since that's what I figured such a tool would be called) and found this, licensed under the GPL: http://mukoli.free.fr/ac32wav/ In the same spirit, I found DTS2WAV (but I have no idea whether this could be distributed): http://hypercubemx.free.fr/html/dts_wav_filter.html I intended to test these tomorrow manually; if I just create the WAV files (with a .wav extension) ought it just work? -- Steve Tregidgo ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss
