Topic says it all. I'd like to learn more about these and what exactly each is doing for me. Here's what I get when a do a "neroaccenc -help"

CODE

Advanced features / troubleshooting:
-lc           : Forces use of LC AAC profile (HE features disabled)
-he           : Forces use of HE AAC profile (HEv2 features disabled)
-hev2         : Forces use of HEv2 AAC profile
                Note that the above switches (-lc, -he, -hev2) should not be
                used; optimal AAC profile is automatically determined from
                quality/bitrate settings when no override is specified.

I've read "guide" out there that advocate using the -he profile, but according to the help file, they recommend using no override as all. Thanks for any info and any links all!

It is recommended to not use these switches, because then the encoder will always choose the best codec and will give the best quality output. The reason why the options are there is because some DEcoders only support LC for example, in that case a HE AAC at 64kbps will sound worse than a LC AAC file at 64kbps using this decoder. So you have to realize on what software/hardware you are playing back the files you encode and choose your option based on that. If your playback device/software supports everything, then using the default (no option) is always the best choice.
