Question about BeSweet using alt-presets or not?

[PlazzTT]

I've given this command line to BeSweet:

"C:\Program Files\GordianKnot\BeSweet\BeSweet.exe" -core( -input "F:\audio.ac3" -output "F:\audio.mp3" -logfile "F:\audio.log" ) -ota( -HybridGain ) -azid( -L -3db -s stereo -c normal ) -lame( --alt-preset 160 )

So, --alt-preset 160 is given to Lame.

But, in the Besweet log file, it says:[00:00:00:000] +------- BeSweet -----

[00:00:00:000] | 'abr 160' preset is used
[00:00:00:000] +---------------------

It says that 'abr 160' is used. Does this mean that --abr 160 was used instead of --alt-preset 160? Is there a difference between these two switches?

--alt-preset 160 is an ABR preset, but differs from the --abr 160 command by the addition of the --alt-preset switches. Meaning this is the same as using --alt-preset 160 with the CLI version of lame.
