[Sandra24]

Any idea?

Would be great if you could help me out on this one!

Hi!

Just load the MTS file into tsMuxer, "remove" the videostream (highlight and click the "Remove" radiobutton) and select "Demux"...

Please setarip_old don't recommend tsMuxer to demux, always use eac3to to demux and tsMuxer to mux (or mkvMergue for mkv)

Thanks.

Why?...

Why?...

When eac3to extract the audio tracks include the delay inserting silence (or cut the audio). When is extracted with tsMuxer the delay is ignored and can produce async in the next mux.

Also the undesired DialogNormalization is cancelled in ac3/dts files, with 4 dB gain in volume (if exist the standard -27 dB value).

If there are multiple input files eac3to can manage the gaps/overlaps between files.

At least with PCM audio the tsMuxer extraction is still buggy.

Hi!When is extracted with tsMuxer the delay is ignored and can produce async in the next mux.I have never encountered such an anomaly when using "tsMuxer" to, as requested by the O.P., simply extract a 5.1 audio file from an MTS (or M2TS) file.

The O.P. is not asking about REmuxing...

I've downloaded Eac3to and More GUI:

I have no clue how to work with this programme.

Could you please explain it to me step by step?

Try the ClownBD GUI (http://clownbd.techxt.com/Downloads/Clown_BD_v0.46b.exe) and place it into the eac3to folder.
Perhaps you'll find that GUI easier to use with Eac3to...

BTW, I also never had any audio sync issues using TSMuxer to demux... and then remuxing again back into different bitrate m2ts files.

Thank you MikeyBK, worked just fine!
