Using the configuration wizard in EAC V0.9 beta 4, I have previously selected, "Use recommended settings (from r3mix forum)" on the page where you browse to locate your lame.exe. When I select this and then goto Compression Options, the Additional Command Line Options line has this in it... %l--alt-preset 128%l%h--alt-preset standard%h %s % First, can anyone tell me what this means? Also, when I try to replace this with.... --r3mix or --nspsytune --vbr-mtrh -V1 -mj -h -b96 --lowpass 19.5 --athtype 3 --ns-sfb21 2 -Z --scale 0.98 -X0 I cannot encode at all! Why is this? If I go back through the configuration wizard and select "Use LAME standard settings.", then goto Compression Options, there is nothing in the Additional Command Line Options line. I can then put "--r3mix" into the ACLO line and I can encode, but, is it really taking this command? Up to now, I've been encodeing with the "%l--alt-preset 128%l%h--alt-preset standard%h %s %". But I'm not sure that's what I want. The quality is great, but the filesizes are rather large. Bitrate is hovering around 210 average. I would prefer to be around 170 average. Forgot to note I'm using LAME 3.92 Any assistance on decipering the EAC/LAME setup would be appreciated.
