View Full Version : Gknot versus BeSweet

I've used both Gknot and BeSweet to produce the required mp3 file from one ac3 source file. I wanted to see if there was any differences in output by using each approach.

What I found was BeSweet produced a mp3 file of size 155,638Kb whereas Gknot gave a file size of 123,839Kb. Therefore my assumption here is that Gknot provides more space for video therefore increases the potential quality.

Or could it be that I've encoded at different bits per sec?

LOL. Well obviously you need to use the same commandline options for besweet as for GK to compare. Some recommended Azid settings:
- Azid in Besweet, 5.1 track: "-g max -L -3db -c normal"
- Azid in GK, 5.1 track: "-L -3db -c normal"
- Azid in Besweet, 2.0 track: "-g max"
- Azid in GK, 2.0 track: ""

And this also applies to Lame settings. Don't bother testing though, the output will be the same.

rmatei,

Thanks for the info. I followed Doom9's guidelines in both cases so maybe the guides need to be updated if you need to get consistancy?

the guides are very updated. they show the most common commandline for BeSweet.
it's SO updated, that it describes features that are only available since v1.3b1 (besweet.notrace.dk), while official release is v1.2.

here is the suggested command, for 1cd rip :
BeSweet.exe -core( -input file.ac3 -output file.mp3 -logfile BeSweet.txt ) -azid( -L -3db -c light ) -ota( -G max ) -lame( --alt-preset 128 --scale 1 )


you can also assert the delay value, by adding -d [value] to "-ota( )".
to downsample the signal to 44.1khz, add -ssrc( --rate 44100 ).

this commandline will give you HIGH quality & speEd. also - it won't create a huge intermediate wav file, like you have now. read here (http://forum.doom9.org/showthread.php?s=&postid=110628#post110628).


btw,
full command line referance can be found here (http://besweet.notrace.dk/cli.html).
