Huge 6chwav - Possible BeSweet bug

[Jan Marijniszoon]

I tried to downmix a 6ch-wav with the BS_Downmix-plugin

There is nothing wrong with the 6ch-wav, because it works in HeadAC3he.

Here is the situation:

BeSweet only supports a 16bit waves, not 32bit floating-point. what kind of 6chwave are you feeding BeSweet with ?

HeadAC3he stream-info gives the following info:

WAV: 48 kHz 16 bit int 6ch 4608 kbps

[DSPguru]

10x for the info, i'll check it out whenever have the time..

[Jan Marijniszoon]

You are welcome.
Thank you too! I will be waiting patiently.

[DSPguru]

hmmm.. your commandline works perfectly in here :confused:
would you mind pasting a logfile of this :
d:\besweet\BeSweet.exe -core( -input g:\6ch.wav -output g:\2ch.wav -6ch -logfilea D:\besweet\BeSweet.log ) -ota( -g max ) -boost( /b2=5 ) -azid( -s surround -L -3db )

[Jan Marijniszoon]

Gave me the following result...

Creates six wav-files of 1 KB each and then crashes.
The 6ch-file is not an ac3-wav...it is one big file with 6 mono pcm wav's in it. It is about 3 GB of size...maybe that's the problem? too big file?

[DSPguru]

the problem is probably with the size.. :(
though, this probably won't help, you can try adding -split( -end 1000 ) to your commandline..


* try processing the file with v1.5b

[Jan Marijniszoon]

Tried both suggestions...same result.

It was you who gave me the idea
You said this in a thread:

multichannel waves are supported (only 16bit waves, though), but downmix to 2ch is only possible by using the downmix plugin.

http://forum.doom9.org/showthread.php?threadid=43269&highlight=dts+guide


So I went to your site and downloaded BS_Downmix.dll.

It works with HeadAC3he, but I rather use BeSweet fot the job.
Seems to me the two-pass downmixing with the overall max gain works better than the HeadAC3he-method. Or I am wrong here?

Anyway, thanks for your attention. I hope it will be resolved in the future.

Greetings,
Jan.

[Jan Marijniszoon]

I have cut a piece of 260 MB from the big 3GB-file.

It works now! So it is confirmed...the file is just too big.
Any change of fixing that?

Here's the log...

[DSPguru]

i don't have such a huge wave file at the moment, so it's a bit hard to track this issue..
anyway, i applied a small hack, please redownload b17 and try your luck..

[Jan Marijniszoon]

This one works...for starters...

The process stops when the 6ch-file reaches 2 GB.
Does not crash though, just stops.

Greetings,
Jan.

[DSPguru]

yea.. i know about that 2gb barrier.. :(

well.. the only thing i could offer now is that you (somehow) split your multichannel wave into 6 mono waves (BeSplit can do this principley, but it suffers from the same 2gb barrier), and then use a ".mux" as your BeSweet's inputfile (text file that lists all mono waves).

[Jan Marijniszoon]

That's no problem. I made the huge file from 6 mono-wav's already. So I don't need to split it again.

How does this mux-list work? Does besweet know what channel (like center or right-surround) it is dealing with?

[DSPguru]

great! so you don't need to mux the mono waves (into mulitchannel wave) prior feeding it to BeSweet. just let BeSweet process the files by itself.

here's an example 'channels.mux' textfile :g:\channelFL.wav
g:\channelC.wav
g:\channelFR.wav
g:\channelSL.wav
g:\channelSR.wav
g:\channelLFE.wav

then use -core( -input channels.mux ...

[Jan Marijniszoon]

The conversion worked...

But the result is not good...very cracking sound and robot-like voices.

I used this mux-file:

F:\center.wav
F:\left.wav
F:\left-s.wav
F:\lfe.wav
F:\right.wav
F:\right-s.wav

Does the order of the channels really not matter?

Sorry that I did not post the log-file.
But that's because there is nothing 'shocking' to see in it :-)

let's eliminate. please give me a feedback on the result of the following commandline :

BeSweet.exe -core( -input f:\6ch.mux -output f:\ -6ch -logfilea D:\besweet\BeSweet.log )

It makes six wav-files of 0 bytes, it crashes and it gives this log:

redownload. retry.

[Jan Marijniszoon]

Does not crash now...

Creates 6 wav-files with identical sizes.
But...the original wav-files have sound, but the wav-files outputted by BeSweet have no sound at all.

The duration of transcoding is shorter...that's because I made the wav-files smaller for shorter proscessing time with testing.

[DSPguru]

1. try with -ota( -g max )
2. please zip "6ch.mux" and attach in here

[Wilbert]

I'm also very interested in this. Tried to downmix 6 pcm tracks to mp3. Used the same lst file as you said on the first page (you can't choose loading a mux file with the gui, but that doesn't matter I guess). Problem is that the size of the resulting mp3 is 0 bytes.

Command line:

"C:\Program Files\Besweet\BeSweet.exe" -core( -input "e:\Gladiator\list.lst" -output "e:\Gladiator\list.mp3" -logfilea "C:\Program Files\Besweet\BeSweet.log" ) -lame( -b 128 ) -plugin( -name BS_Downmix.dll -func NoLFE -6ch )

Looks like it tries to convert every pcm track to a mp3 file?

[DSPguru]

lst & mux files have the same structure. BeSweet cannot differ between the two. you'll have to use the ".mux" extension. use the "copy command to clipboard" button and then fix the commandline and run manually.

edit : if you're into dts transcoding - just wait a couple of days, and you'll get an end-to-end solution.

Thanks, a bit stupid that I didn't try this.
