BeSweet 1.4 and -ota( -g max )

[mikeson]

@DSPguru:

Thank you for releasing stable 1.4 version of BeSweet :)

But I have one question about gain between versions 1.4RC8 and 1.4
Please have a look at these log files.

Command line was the same for both encodings. Using OggDS 0.9.9.3.

Gain difference is between all encodings that use Dolby Surround 2 downmix. If I use Dolby Surround logs are the same:

So why is there difference between 1.4 and 1.4RC8 gain when used DS2 downmix? Which one is correct?

Thanks

[DSPguru]

BeSweet v1.4 should be more debugged than RC8.

if you like to help me trace this down, please do :
1. compare the v1.4 ota maxgain on ds2 to v1.4RC6 (or older) ota maxgain.
2. compare v1.4 ota maxgain to v1.4 azid maxgain to v1.4 max postgain.
post all logfiles.

@DSPguru:

Ok, I'll do it, but the oldest version of BeSweet I've got is 1.4RC7, so can you please provide me any older?

[DSPguru]

http://DSPguru.notrace.dk/BeSweetv1.4RC5.zip


btw,
why don't you go for the hybrid mode with postgain ?

[mikeson]

Is it better?

it's only for testing..

@DSPguru:

Transcoding in progres...

Meantime may I ask why do you suggest in http://forum.doom9.org/showthread.php?s=&threadid=32814 hybrid mode with PreGain 10db + PostGain? Should I use Dialog Normalization with these settings.

Currently I use auto pregain and no dialog normalization. Am I doing wrong?

Here are the results:

It seems that in 1.4 using DS2 downmix azid's gain is the same as ota's gain. So which one is correct? Azid or ota? 1.4 or 1.4RC5. I'm a little bit confused. :confused:

I'm a little bit confused. :confused: as you can see, the OTA gain is almost the same in v1.4 and v1.4RC5, and OTA is always more accurate than azid. so i would say that v1.4 is the good version.

Currently I use auto pregain and no dialog normalization. Am I doing wrong? no. on a pregain two-pass, dialog has no effect.

@DSPguru:

you shouldn't use both..

I did it just because of testing.


It seems as from 1.4RC5 to 1.4 -ota( -g max ) gives a little bit different values, why is that? Did this code changed between versions? Why is it now (1.4) the same as -azid( --maximize ) found values?

Did azid's max gain seekeing code changed too in 1.4?


Thank you for investigating ;)

[DSPguru]

OTA gain is always correct.
watch any of your encoded files in a wave editor and you'll see they are normalized.

Azid's gain might have been wrong in previous version, but is now correct in v1.4.

yes, i kept doing fine tunings to DSUR2 implementation inside BeSweet, and now i feel pretty good with the result in v1.4.

the max-gain LEVEL isn't really important as an absolute value since it depends of the coefficients i use inside BeSweet, the only thing that should bother you (and me!) is a case when you use BeSweet in a two-pass mode in order to get a normalized signal, and then the result track is not normalized.

again, you might have found a bug, but for now - i'm very confident with v1.4 .

I'm just trying to improve BeSweet in way I can do. Thank you for explanation, I feel satisfied now :)

you're still invited to test whether BeSweet's output isn't normalized.
