Some converters allow you to output a naked file, one without the MP4 container.
The two players I use the most, vlc and juke both play back the naked aac-he files just fine.
However a naked aac-he file has a different identification than an MP4 container file.
Some software, such as this and iTunes don't recognise the aac-he file without the container due to the different identification.

The reason for not using the container in the past was to reduce the overhead. An audio cd inside an amazon box takes up more space than a bare cd. This is the same idea.
In the past the overhead was the difference in a few extra tracks on my 1gb USB MP4 player. Today the few bites to a K or so doesn't make much of a difference.
ffmpeg -i input.aac -c:a copy output.mp4

It's dirty but it's the first thing on google! ;)
Just make sure the frmpeg in the folder is updated. As the current version uses aac-he by default and the older version may not properly recognise the he extensions and strip it from the file in remusing as it does when MP3+ and atc3 files.

Also looks like, quickly scanning google, many people use handbrake to do container passthrough now too. Haven't tried that myself but there's a flood of info on it.
Like I said as long as you do things in order it's generally quite easy. But conundrums arise so if you have errors Post back.
I'll post the script for you as soon as I get a chance. (To find it).
At the time I was looking to jam as much onto a knockoff mpeg player that had 2 gig of space. MP4 containers add a few K to about a meg in overhead. But 5 years later and that's no longer an issue.
I don't have any Ill will over this though. Back then naked files was a "hacker" thing that the mainstream didn't understand; making accommodations for a tiny percentage of users probably didn't make sense.
Now it's just overhead and we've generally learned to make due with a few (pointless) lost KB. With he there's even less concern. He at it's highest setting has consistently proven itself. A 5 minute file taking about 4 meg on full range has been "cd quality" in blind tests 98% of the time. An extra meg for the containers at most, still is better than monkey and flac at 500 meg+ for the same quality.
My suggestion for future audio is set your current converter to use aac-he or xahe in an mpeg 4 container.
Again I'll post the script as soon as I find it. It was some time ago. I may just google it ; lol.
I've both given up on having a direct implementation here, and moved on from aac to aac-he.
I used a script from videohelp to put all my aac-he files I already had in MP4 containers (m4a) but when my converter, ezcdda, updated a while back to including he out of the box I've stuck with that for the codec in an MP4 file.

If you want the script to put your files in containers, I'd be happy to pass it on. You'll need to load mp4box from an elevated prompt and side load the script, so typing in a command is required, but after that the mp4box interface is self explanatory;
Right click on the folder of MP4box and chose run a command prompt or open a command prompt here

Type mp4box.exe /l aacmpa.sy b

point it to the directory you want to run the containering on e.g. C>users /mycomputer/music etc

Type y or n for the question on subfolders,

and type r for run.
In this cas yes, it also appears in Thai and Cyrillic based languages as well.
While it's not an issue for downloading corrections (don't really need to SEE the text to save it, I guess), as I said I'm having random issues getting it to save if I enter text manually; it saves boxes instead of what I typed out.
Hi; appears that download unicode text from Discogs AND MusicBrainz to 9.1.0 fails.
Properly tagged files already existing show just fine,

but adding tags from the internet shows the unknown code square glyph.

Attempted to enter the proper text manually ALSO gives me unknown code glyphs. Though it displays properly WHILE I'm entering it. When I click enter/return the display input changes to square glyphs.

SOME of these resaved, newly updated and saved, tags show up properly in another viewer while others don't.

If you just rename the file to .mp4 does it work in Jaikoz ? 

I get the message The following Audio Files are not recognised as audio files, they may be corrupt.

An aac file is a raw audio stream
Using iTunes as an example
When you download from iTunes you get an m4a file
This is a renamed MPEG 4 container file. It contains an aac OR mp3 file, an "apple text" XML file and a Meta data utf -7 file
Mpegla states remaining conventions for.container files as such:
m4a for audio
M4b for books (audio alone or audio and text/images)
M4v for video
All are containers holding one or more files

Using mp4box you can extract a non-protected iTunes file and get *.aac *.XML and *.apl
Often you can also get JPEG or PNG files as well, or on older cracked files a qti image

Just like flash, you can extract *.vp8, *.aac and *.adi

Aac itself is an audio file, commonly found in a container file but not always

As a side, microSoft and emusic also have aac files in some regions. so does Tmobile music And virgin tunes
They Rename the aac file to m4a. this is an out of spec use
I can rename a .txt file .m4b but it's still a text file. Winamp, apple books, kindle fire and nook will Load the files as multimedia books, and just display the text but it's still a plain text file

Hope that helps
Guess I'm just outside the common userbase for you.
Most home server receivers (disc servers) use AAC for stored audio data. In my case, an Elite SX Audio server, which uses HE-AAC (AACHE). I use 512kbps for home, and 64kbps for my mobile player. I /believe/ the range is 12kbps to 7mbps, but not sure.

Advanced Audio Codec is an MPEGLA sponsered codec, that can be used raw (AAC, AHE, and HEAAC), or in the mpeg container (mp4, m4a, mpeg4).

As I'm sure you are aware; iTunes, Microsoft, and Play! files (among others) are not raw audio, they're containers that include the aac audio file and other files as well, (including DRM and licensing xml files).

FWIW; I didn't mean anything by 'fix' btw. more as add....

My portable player simply requires me to pay extra for a parser for mp4 containers. but plays AAC out-of-the-box.
Any chance this will be 'fixed' in the future.
Remaining an AAC file mp4 (apple and others) is technically a violation of the specification.
Hate to have to rename my entire library just for that.
Otherwise thank the internets for Bulk Rename Utility
any idea from the logs?
Tried sending a file but got this

HTTP Status 500 -
type Exception report
description The server encountered an internal error that prevented it from fulfilling this request.
note The full stack trace of the root cause is available in the Apache Tomcat/7.0.30 logs.
Apache Tomcat/7.0.30
file and log
Maybe I'm missing something; but I can't get my files to load. They're all AAC. Opening from the file menu and drag and drop both do not work.
Does jaikoz not support aac files?
