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:

So it does not crash....just produces nothing :-)

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.

hmmm.. your commandline works perfectly in here
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.ph...ight=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.

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?

you bet!

[Jan Marijniszoon]

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

I also tried the order of channels in your suggested mux-example...
Same result.

[DSPguru]

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 )

[Jan Marijniszoon]

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