6ch Wav to 2ch stereo wav

[ranosb]

Im trying to convert a 6ch .WAV file(DTS 48 Khz) to a standard 2ch Stereo WAV(44.1 Khz) using besweet. Can this be done? Im using the following command line but the new wav file is still dts, how do I make it a standard analog stereo wav file?

The resulting file has no change, still a 6ch wav.

"C:\Program Files\MKV Editing\tsMuxeR_1.9.9\BeSweet\BeSweet.exe" -core( -input "C:\0_TEMP\MKV TEMP\01 Roxanne.wav" -output "C:\0_TEMP\MKV TEMP\01 Roxanne-New.wav"
-plugin( -name BS_Downmix.dll -func -2ch )
-logfile "C:\0_TEMP\MKV TEMP\Results.log" )

Install and use BeSweetGUI to do this instead of your command line script. I don't know what's wrong with the script, but I use the GUI so I don't have to worry about command line options. You can definitely do this with BeSweet.

You can find BeSweetGUI here:
http://dspguru.doom9.org/
Go to the "Stable" link to find it.

I went to the command line cause the GUI did not work; and just another 6ch wav file..

Ok using foobar to downmix the dts into 2 track stereo
Im actually using version 0.9.6.8.



Output format > Wav

With converter setup active DSPS > convert 5.1 to stereo

The result wav file? 6ch wav file!

Have you tried to use the Belight GUI for BeSweet?
https://www.videohelp.com/tools/BeLight

(The BeLight files, should be copied into the same directory as where your BeSweet is).

Belight has some settings for PCM/WAV output, which should meet your needs.

I have once been working with a 5.1 6-channel wav file, that was encoded with DTS. It had the correct WAV-channel-mapping: FL, FR, C, LFE, BL, BR. But that totally confused MeGUI/ffmpeg AC3, who read it as DTS mapped: C, FL, FR, BL, BR, LFE and thus mixed up C and FL, and LFE and BR. Took me a while to figure that out. (MeGUI/Eac AC3 got the wav map right - hmmm). Maybe something like that is confusing Besweet.

Avisynth can be used to fiddle with channel mapping:
http://avisynth.org/mediawiki/GetChannel
three script lines like:
LoadPlugin("C:\Programme Files\Blaah\nicaudio.dll")
audio = NicDTSSource("F:\Blaah\Filename.wav",6,1)
return GetChannels(audio, 1,3,2,6,4,5) ´
should remap from WAV to DTS.

MeGUI can take an Avisynth script as input, with any other format than WAV as output. I don't know of a tool which can take an Avisynth script as input, an WAV as output though. If your 5.1 source at the end of the day should end up as somethingh else than WAV - I would consider MeGUI.

To be blunt, you're not doing it right. There is some option you are missing if this is happening to you. Unfortunately for you, I am not able at this time to run BeSweetGUI and do this for you and show you every step that you need to do to do it. But you definitely should be able to do this with BeSweetGUI.

eac3to might also be able to do this. Try that.

Very nice plugin, thanks...
Ok using BeLight did produce a 2ch stereo wav file, in dts form (It still sounds only hiss) because my winamp doesn't have the dts plugin so hiss is produced. I thought it was supposed to convert it to a standard analog file?

Which could then be used with something like iTunes to convert to applelossless,...

DTS-WAV is not the same as uncompressed WAV.

MPC-HC has built-in support for all flavors of DTS streams.
AC3Filter can do the trick as well.

But I still don't understand why so many people still prefer
the outdated "BeSomethings" to eac3to.

ffmpeg has an ALAC encoder:

ffmpeg -i stereo.wav -acodec alac output.m4a

Im new to this, could you explain?

What are Besomethings to eac3to mean? Im not following you on your meaning sir.

I will look into ffmpeg as you mentioned... Which ffmpeg GUIs/Frontends do you recommend?

ffmpeg -i stereo.wav -acodec alac output.m4a

unknown encoder 'alac' message...

Where you getting this alac acodec, this is apples?

Thanks!

ranosb: I just made a fresh installation of the latest Besweet and Belight, and tried to duplicate what you did.

I tried various settings, but nothing worked.

Even tried to rename the fileextension from *.wav to *.dts.

So I have to agree with El Heggunte and others who says the old Besweet'ies don't work with a DTS-encoded wav file.

Other tools work, but give up Besweet for this task.

Uncompressed .WAV contains LPCM audio.
DTS-WAV is a compressed stream plus a stereo_16-bit_4##000Hz WAV header.
Trying to playback a DTS-WAV file without the help from AC3Filter
just gives you a lot of noise.

Upgrade to a recent version of ffmpeg

( I'm still using the 0.5 one, but will look for a SVN-build which encodes
"foobar2k-compliant" ALAC files ).

BeSweet, BeLight, BeHappy.

Using dBpowerAmp MusicConverter does the same as BeLight , produces a 2ch dts file.




Taking a regular 2ch wav and running it thru any of belights quad/5ch/5.1 produces a file that when trying to burn with NERO, produces a "FILE FORMAT NOT SUPPORTED"

Apparently there has to be a different kind of conversion here...
