PCM audio

[Floatingshed]

I'm new to Bluray ripping. I have a m2ts file which DGAVCindex opens fine and reports has h264 video and pcm 48khz 24bit audio.
I can open the h264 video in avisynth no problem but no source I have will open the pcm.
Google searches suggest that Directshowsource should, but it doesn't (I have all audio codecs enabled in FFDshow).
Does anyone know how to do this please?

eac3to can extract/convert the PCM from the m2ts to WAV/W64/FLAC (losseless) or AC3 (lossy)

Since posting my question I've been trying a few things...
I tried eac3to and it did produce a .wav file but it appears to be headerless and no software I've tried can play it.
Is there no way to import the pcm directly into an Avisynth script?

NicAudio.dll either NicLPCMSource() or RaWavSource()

[tebasuna51]

Use the output .wav or .w64 from eac3to and open in AviSynth with RaWavSource (included with NicAudio.dll)

You can use also .pcm output from eac3to but you need inform the samplerate, bitdepth and numchannels (info included in waw/w64 header)

Thanks guys.

I'm afraid that none of the above suggestions were successful.
RaWavsource complained about incorrect number of channels (there are only 2).
LPCMsource gave no error message but also no audio!

I found that loading the pcm into cooledit pro as: 48/stereo/24bit packed Motorola pcm is the only thing that I can get to work...

Try this:

input.mpg output.ac3 -demux -down2 -blu-ray -192 -resampleTo44100

You should be able to rename the m2t to mpg without breaking anything.

Sorry it seems RaWavSource () has found some header it likes and is trying to use that, it is not reading raw bytes as you would like. We probably need to revise how that code works or add a simple RawSource().

NicLPCMSource() will read raw bytes according to the description in the call, however the byte order cannot be specified.

Please put the eac3to log file when you run (where X is the PCM audio track):

eac3to your.m2ts X: audio.wav
