I'm new to encoding and i have few bluray disk and i am trying to convert into MP4 container and encoding video was good but when it comes to audio i'm having trouble encoding HE-AAC or HE-AACv2. I encoded using MeGUI HE-AAC 72kbps but the quality was really bad. I went through SHAANIG's encodes and his sound of HE-AAC 64 was lot better compared to my 72kbps.
Are there any encoding settings to encode audio. If yes please do tell me.

from my point of view is very good ABR mode with two pass. But I cant achieve it in MeGui. Dont know why -2pass (command, in extra tab) gives me error on audio stream.
Somehow in MeGui achieve this -2pass -br 72000 -he
I know it is not your question, but you can do audio separatelly in LameXP, which works with Nero very well and supports 2pass for HE aac. It is very easy to use free program.
Or ask someone how to force -2pass nero ABR mode in MeGui.
So if you want great sound give a try LameXP and mux lately together.
-2pass : Enables two-pass encoding mode.
Note that two-pass more requires a physical file as input,
rather than stdin.
For 2 pass to work, MeGUI would have to know to decode the source to a wave file, then use the wave file as the input for the encoder.
By the way, the Nero help file also tells you not to specify HE or HE2.
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.
If I remember correctly, the Nero encoder is the only one that automatically chooses an AAC profile. For FDKAAC and QAAC you have to specify one if you want something other that LC-AAC (the way I remember it).

I assume you're encoding stereo tracks? 72k would be extremely low for multichannel audio.
Apple's encoder seem to be the best at low bitrates these days.
Although.... why do people use such low bitrates?
For a 2 hour movie 72k results in a 64MB file.
For a 2 hour movie 125k results in a 112MB file.
For a 2 hour movie 175k results in a 158MB file.
125k is roughly (according to foobar2000) the bitrate you'll have after encoding an average CD track with Nero's q0.4 VBR quality setting, and for the default q0.5 it's 175kbps, but as stereo "soundtrack audio" is usually more sparse, it'll probably end up lower.
When encoding multichannel audio, maybe there could be more of a need to keep the bitrate down, but for stereo I'd definitely prefer to steal 100kbps from the video bitrate (if it came to that) and encode the audio at a higher quality.
MeGUI now aren't you? I can't think of an encoder off the top of my head the doesn't support stdin (pipes).
I mostly use foobar2000 but if you're encoding the same source with the same encoder using the same settings the result shouldn't be any different anyway.
Normally you'd use a pipe (the decoded audio is sent directly to the encoder) but foobar2000 comes with a NeroAAC encoder preset for 2 pass encoding, so at least it'd make creating a temporary wave file an automatic process.
That aside, you can use any command line encoder with foobar2000, as long as you download the required files yourself (foobar2000 only comes with the encoders that can be legally included).

foobar2000 encoder pack.
The main differences are it doesn't require the VC2008 runtime and it accepts 32 bit float as input (initially it converted it to 32 bit integer but that's no longer the case).
The encoder pack comes as an exe but you can unpack the contents with 7zip.
Hello, I am New in Encoding and Want to Know About Audio AAC, I Had Encoded a Movie and Audio Bit Rate at 96kbps and Audio Quality is Really Found,
Same Video I had Found a Very Well Better Quality with Audio 32kbps,
Here is Mediainfo,

Will You Guys Please Tell Me Which Video Encoding is Used to Encode This Video :
There is no best way in anything. What is good for one is bad for another. You could try EZCD. It has a trial and does he-aac multi channel very well and you can normalize it too to 89db etc. I wouldn't go lower than 192kbps for he-aac 5.1, but some go lower. 72kbps setting in EZCD would give you stereo 2.0 and vbr up to 79kbps. Setting it to 80kbps then becomes constant 2.0 stereo.
