I'll leave the side comments out
but lame.exe --alt-preset standard --nogap 01.wav 02.wav 03.wav seems to be working as lame is picking up the presents of the nogap parameter and it is encoding at it usual --preset slow pace (both with single spaces and double spaces)
I can't confirm as the only CD I have handy would not really show up the use of nogap too well.

anyway in the mean time I'll see if i can put together a script or batch file to make it a bit easier then the writting the full command line everytime.

PS what made you change over?
