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 |

http://www.audiocoding.com/ is the home of FAAD2, a free (GPLed) AAC decoder with HE-AAC support.

An encoder can be downloaded from 3gpp.

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). This post has been edited by Dan Nelson: Feb 22 2005, 04:48 |

Thanks and Regards Shreya 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 Matthieu matthieu.laurent@purplelabs.com |

I hope somebody works out what's going on here...I'd love a native OS X HE-AACv2 encoder - having to use Virtual PC is downright painful.

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... -------------------- http://www.unite-video.com/phpbb/viewtopic.php?t=5412 :: An overview of all lossless Audio Formats (in french language ;-)

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/ Cheers This post has been edited by rootkit: Dec 4 2007, 03:08 |

Sorry I'm pretty new to this 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?
