Posted: Tue Aug 02, 2011 8:13 am
Nero AAc suport 2pass encoding already, but Audiocoder seems to skped that option.
Please integrate this in the next update.

Usage:
neroAacEnc.exe [options] -if <input-file> -of <output-file>
Where:
<input-file> : Path to source file to encode.
The file must be in Microsoft WAV format and contain PCM data.
Specify - to encode from stdin.
Note that multiple input files can be specified, they will be
encoded together into a single output file with chapter marks
indicating source file divisions.
<output-file> : Path to output file to encode to, in MP4 format.
==== Available options: ====
Quality/bitrate control:
-q <number> : Enables "target quality" mode.
<number> is a floating-point number in 0...1 range.
-br <number> : Specifies "target bitrate" mode.
<number> is target bitrate in bits per second.
-cbr <number> : Specifies "target bitrate (streaming)" mode.
<number> is target bitrate in bits per second.
When neither of above quality/bitrate options is used,
the encoder defaults to equivalent of -q 0.5
Multipass encoding:
-2pass : Enables two-pass encoding mode.
Note that two-pass more requires a physical file as input,
rather than stdin.
-2passperiod : Overrides two-pass encoding bitrate averaging period,
<number> : in milliseconds.
: Specify zero to use least restrictive value possible (default).
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.
-ignorelength : Ignores length signaled by WAV headers of input file.
Useful for certain frontends using stdin.
