![]() However after few tries it seems that the library is already missing Now scanning for virus and malware.I installed Audacity 2.1.0 and try to install the ffmpeg library On top of this, when it wasn’t crashing, there didn’t seem to be any options greater than 6ch for audio lossless files. SUPER was a bad idea! I was able to skip crapware in the install… but still it had some malware or something that throws some junk on the browser when it starts. See this thread: 7.1 Audio on 5.1 speaker system = DTS core? | AVForums I believe he explains a bit.Īssuming the disc is not copy protected (or has already been cracked), you might try SUPER. This may be normal for this type of 7.1 disc. There is no PCM track that the software is able to see, and it may not exist on this type of disc. Normally the multi-channel 5.1 tracks seem a bit suppressed, and I need to amplify them a bit before I archive them. I’m well aware of Clipping, and I can see when that happens in my channels in Audacity. Also I’m used to ripping music from Blu-Ray. However then my receiver is doing the decoding in DTS-HD straight from the Blu-Ray. Mixing is done by addition (summation), so if you don’t down-mix correctly (scaling-down the levels) you can get clipping (distortion). A downmix, or an un-decoded Pro Logic track sounds usually just fine in stereo. Therefore it gets garbled.Įither way, it shouldn’t be garbled. And/Or FFMpeg is lumping them together calling it 6 when it should be 8. So now I’m starting to believe the above poster who said ‘that the 2 rear-tracks were matrix’ed’ like pro-logic. Does it sound garbled when played back with all 6 (or 8) channels? Maybe try playing the Blue-Ray with all of the speakers disconnected except the rears, to see what’s actually in those channels. That could be normal for this particular recording… I wouldn’t expect it to be distorted, but I wouldn’t expect it to sound “good” or “right” by itself without the other channels. Then when you install, be careful about the options because it might want to install some crapware along with it (I don’t remember).Īnd the rear channels do seam a bit garbled. There are ads for other software on their website, so make sure you are downloading and installing SUPERsetup.exe. SUPER uses FFmpeg, but I believe it includes at least one additional encode/decode library, so it’s worth a try. It can convert to/from many formats and/or extract the audio stream, but I don’t know if it supports 8-channel DTS-HD. You might get better help there… Or, maybe there’s a (illegal) utility for copying/extracting Blu-Ray audio? I know there are such tools for DVD.Īssuming the disc is not copy protected (or has already been cracked), you might try SUPER. There are websites/forums that specialize in copying/cracking DVDs & Blu-Rays. Regardless, according to the posts above, none of these is the PCM track.įrom what you’ve told us, there is no PCM track. So if you want WAV and the whole-continuous movie/program, you’d need to extract to 8 separate WAV tracks. Note that single 8-channel WAV file for the whole movie/program would exceed the 2GB/4GB WAV file size limit. You’d have to extract/decode the audio to a format Audacity can open. I have no idea what DCA is, but again the packaging or disc menu may give you a clue. is DCA I’m assuming that is the ‘DTS encoded’ track. (On video, it’s usually called LPCM for linear PCM, but CDs and regular WAV files also use linear PCM.) PCM the same underlying format as WAV and the same underlying format as audio CDs. AC3 is a lossy-compressed format sometimes called “Dolby Digital”. (DVD/Blu-Ray players can down-mix the surround, but a separate “intentional” stereo mix may sound better than a down-mix.) It’s common to have a 2-channel stereo track for people who don’t have surround sound setups. Of course, you can listen for different languages. The Blu-ray menu should list the 5 audio options and give you a clue about what those tracks are, although they won’t be “numbered” and you might have to guess which is which. ![]() I’m assuming some of them are different languages. (Home theater receivers with HDMI can usually decode all of the Blu-Ray formats.)Īudacity reports 4 to 6 different encodings. I also don’t know of any software that can decode/extract the matrix channels, except maybe WinDVD or other real-time player software. ![]() I don’t know if FFmpeg can decode TrueHD or DTS HD and I don’t know of any other software decoders for those formats. Does the Blu-Ray packaging indicate those formats? LPCM, Dolby True HD and DTS-HD are capable of 8 discrete channels ( Wikipedia). I’m reading a blu-ray and I know its encoded with 7.1. Since none of those are 8-channels, the additional 2 channels for 7.1 are probably matrix encoded (like the old Pro Logic encoded into 2 channels).
