Blu-ray DVD (BDDVD) in the 5.1LPCM audio processing
Mar 09
Send a friend gave me over the AIR's BDDVD (D5 sub-volume burn rar), get my study of this object generated interest.
First, decompression, with the MPC play m2ts files, found images, no sound. View audio decoder using AC3Filter, for Nero Audio Decoder, decoding and normal. Maybe this is the legendary E-AC3 of the bar, AC3Filter does not support.
Here's what the audio approach, part of the way of a tutorial from the doom9
Of the original quote the following address:

First, determine the feature-location, natural is the size of the largest m2ts.
=============================================
Method 1:
Detection tracks with xport
Download address:
http://share.slodt.com/vempx/VideoTools/xport.rar
Format
Code :———————————————— ——————————– xport-h 00003.m2ts 1 3 2/3/4/5/– ————————————————– —————————-
The third figure is to be replaced, said that track the number of audio streams, when the cmd run this command, it will automatically separate tracks. Please note that the last few lines, where indicated the format of this track to confirm whether you want to format, it is not, then the termination of operation, replace the third number.
Code :———————————————— ——————————–
LPCM Audio Mode = 3 / 2 + lfe
LPCM Audio Bits / sample = 16
LPCM Audio Sample Rate = 48000
————————————————– ——————————
Said here is the 5.1 channel LPCM, bit depth 16bit, sampling rate of 48000, exactly what I want to track, then waited for him to continue to separate finished bar.
Mpa format is separated, in accordance with doom9 the original software, and need to convert flac to wav.
flac.exe this everywhere I will not quote download
Code :———————————————— ——————————– flac -0 – force-raw-format – endian = big – channels = 6 – bps = 16 – sample-rate = 48000 – sign = signed-o “temp.flac” – <bits0001.mpa
flac-d temp.flac-o temp.wav
————————————————– ——————————
Transit through the flac codec, can be LPCM.
===========================================
Method 2:
Haali's splitter directory under a GDSMux.exe, this thing is very powerful, haali worthy to write separator people.
To run this tool, right-Add source, select the confirmation of the m2ts files will be automatically listed into orbit after the stream, hook on the needs of that 5.1LPCM, and then enter a name below, point Start, will begin to appear Remux a MKV.
Has finished, the inside of the LPCM can be extracted.
When this method does not work, please use the method of a
However, the definition 5.1-channel LPCM have different needs to be done manually change, or encoded sound problems.
Download Wavewizard 0.45b

Run, press the keyboard F2, remove the inside has been defined, point New to add a 6 to 6 of the move channel
Channel Definition 012,534
OK to save, and check on the new channel mapping
Then the following enable channalmapping hook on.
OK back to the main interface, click the add to get. Wav file to be added, according to the keyboard F4, confirmed that enable channelmapping checked, output formar select raw samples, and then OK back to the main interface, convert points to start the conversion, after which will be a raw audio.
This audio encoding is now necessary to flac
Code :———————————————— ——————————–
flac -8 – force-raw-format – endian = little – channels = 6 – bps = 16 – sample-rate = 48000 – sign = signed-o “final.flac” – <temp.raw
————————————————– ——————————
After we get the desired 5.1 LPCM track.
================================================== ===
Methods from doom9 post, I just look to promote only.
Directly DGIndex open m2ts, can also be isolated from the audio, but it is one. Pcm's weird files, I do not know how to handle.
xport separated the mpa, need flac transit; gdsmux is to re-remux an mkv, but also extract, two methods are not very simple, but ultimately they need to adjust the channel to use Wavewizard, or encoded sound out of a problem.
doom9 there is a tool called eac3to, presentations are able to 5.1 LPCM to Flac and other functions, but I could not handle that thing, DG separated. pcm, foobar can not be broadcast, but this tool can convert, but out of something is also full of noise error flac only. After that complex steps to convert out of foobar you can choose to broadcast wav, this tool can not convert the … …
Goosh, did anyone know why?
