Hi All,
I want to know where I can get the publicly available free source code of Enhanced AAC plus. Also I want to know where can I get the standard for Enhanced AAC plus or some documents related to Enhanced AAC plus.
Thanks and Regards
Shreya
Full Version: Enhanced AAC plus free source code
http://www.audiocoding.com/ is the home of FAAD2, a free (GPLed) AAC decoder with HE-AAC support.

I wanted the source code of Enhanced HE-AAC and not HE-AAC.
Can I get it from here. Has it been supported in FAAD2.

An encoder can be downloaded from 3gpp.

FAAD2 has supported "Enhanced HE-AAC" (HE-AAC v2), or in other words, parametric stereo, for quite a while.

Hi,
Thanks for your response.
I have downloaded the code from 3gpp but i am not able to debug the code. Have you come accross such error.
Waiting for ur reply

FAAD is decompresor, but how to make Enhanced HE-AAC files?
3gpp.org gives only sources:|

I haven't tried to debug. I've only compiled using ICL. My binaries can be found at http://kotisivu.mtv3.fi/ware.purkki/ .
The 3G code works perfectly, including debug, when compiled in VC++. Linux I haven't tried.
The problem is the "source" distribution actually includes two binary libraries: libaudio.a, and libisomediafile.a. Not much source in there..
To build libisomediafile, you need to download http://www.iso.ch/iso/en/ittf/PubliclyAvai...nce/systems.zip and build the systems/mp4_file_format/ directory. I haven't found where the source to libaudio.a is yet (NAS probides a libaudio library, but it's not the same).

I assume libisomediafile is responsible for creating the mp4 container, and libaudio is for reading the input file, since without either library, I get link errors like:
./src/main.o(.text+0x273): In function `main':
: undefined reference to `AuChannelOpen'
: undefined reference to `AuChannelClose'
: undefined reference to `AuChannelReadShort'
./src/mp4file.o(.text+0x21d): In function `MP4FileAddFrame':
: undefined reference to `MP4GetHandleSize'
./src/mp4file.o(.text+0x3a5): In function `WriteMP4File':
: undefined reference to `MP4WriteMovieToFile'
./src/mp4file.o(.text+0x491): In function `CloseMP4File':
: undefined reference to `MP4DisposeHandle'
, and if I build libisomediafile and link with that, the MP4* functions link okay, and the only errors that are left are the AuChannel* functions.

These libraries are precompiled. If I want to port this code on say Arm processor, then I need the source code of these libraries so as to compile it for Arm.Can I get this source code or these libraries can itself be used for porting on Arm ?

I would guess that the source to libaudio is available somwhere at either http://www.3gpp.org/ftp/Specs/html-info/26-series.htm or http://www.iso.ch/iso/en/ittf/PubliclyAvailableStandards , but I wouldn't know where to start looking. Maybe someone should email the 3gpp people and ask them...
Has someone found the source code of libaudia.a?
If yes, could he/she tell me where to find it?
Thanks

With the last 3gp sources, these libs are in lib/linux folder. This encoder works fine with my Linux distro.
@loophole :: compilation under MacOS should work with gcc...
Unfortunately those libs are not provided for OSX/PPC.
A very nice thing would be to replace those binaries libs by some source code.

The encoder's requirements as far as processing the input file are pretty light; the only functions it needs are AuChannelOpen, AuChannelClose, and AuReadShort. It should be easy to write wrappers for those that call your favorite soundfile-reading library.
I've edited a bit the source code and i've written missing Au* functions.
I had to keep in mind endianness to make the encoder works on powerpc and other big endian machines.
You can get it here: http://teknoraver.campuslife.it/software/mp4tools/

I have compiled it on Linux PPC, not MacOSX PPC.
You culd try this CFLAGS: -I.. -I../../src -Wall -W -ansi -pedantic -Wno-long-long
The error was in libisomediafile, that had two subdirs, win32 and linux, so i've stripped the win32 out.
Dunno about OS X, never had it, but i suggest you to use the latest gcc compiler, since i'm using gcc 4.1.0 under linux.
What gcc -v says about his version?

Isn't Mac OS 10.4.6 64-bit?
I have an issue with AMD64 that i haven't under i386, can you reproduce it?
issue samples are there: http://blueangel.us/mp4tools/ct-he-aac/
It seems a CT bug.

Parts of it might be dual architecture, since the G5 processor is 64-bit. But the G4 processor in my PowerBook is 32-bit. Perhaps you can tell me how to possible reproduce this, so I can give it a try?
@loophole. It complains about the missing malloc.h file. I just copied the malloc.h file from the 10.4u SDK into the libisomediafile folder and it compiled successfully

Nope, on BSD malloc.h is replaced by stdlib.h IIRC

Well, I had the same compile error as 'loophole' the first time. But after copying the malloc.h file it compiled successfully. 
Edit: I have compressed a couple of tracks to 32 and 48kbps. The sound quality is really impressive for the bitrate.
rootkit, the problem sample sound fine to me. So I guess it don affect Mac OS X on 32-bit either...
I just changed #include <malloc.h> to #include <malloc/malloc.h> in MP4OSMacros.h
i've edited the program to save raw AAC streams with ADTS header instead of mp4 files.
stay tuned
stay tuned
Here it is: http://teknoraver.net/software/mp4tools/
It doesn't works under AMD64, but still should under powerpc.
Feedback is welcome!

The Right Thing™ to do is to include "stdlib.h". According to the C89 standard, this is where malloc() must be. It's safe to assume that any system and compiler you'll ever come across implements C89. Using "malloc.h" is an unportable Linux-ism.
Another good porability reference is The Single UNIX Specification. When in doubt, assume what it says, and consider anything else odd. (By this definition, yes, Windows is very odd indeed.)
Hi all,
I see a libisomedia.lib in the decoder module. I extracted the files from system.zip from www.publiclyavailablestandards.com. My problem is how can i port this on ARM processor. i see that it is being compiled for intel platform. for win32 platform there is a file named w32filemappingobject.c , what should be the corresponding file for ARM core. I am using RVDS and win32 can not be used. Some one who knows the solution give me a mail at sateeshchandra@gmail.com.
Thank you,

Noise--hundreds of horses are running. Surprised , the fixed code before 630 is fine. Also , I found the problem happen in encoder code ,not decoder code. Maybe Coding technology release it before testing. ? The difference between 26411-630 & 26411-620? Anyone is kind to tell it?

IIRC it's the same with MP3 encoders. Shine, also fixed point, produces files with a bad quality too.
