![]() ![]() Only the FAAC changes to this ISO MPEG-4 reference code are licensed under the LGPL license. Licensing įAAC contains code based on the ISO MPEG-4 reference code, whose license is not compatible with the LGPL license. FAAD2 version 2.0 was released on 6 February 2004. The SBR decoding support (HE-AAC) was added in the version release on 25 July 2003. ![]() It was first released in 2000 and it did not support SBR and PS audio object types. FAAD2 is the successor to FAAD1, which was deprecated.įAAD is Freeware Advanced Audio Decoder. It contains a library ( libfaad) that can be used by other programs.įAAD and FAAD2 were originally written by Menno Bakker from Nero AG. It is MPEG-2 and MPEG-4 AAC decoder and supports MPEG-4 audio object types LC, Main, LTP, LD, ER, SBR and PS, which can be combined also to HE-AAC and HE-AACv2 Profile (AAC LC+SBR+PS). Mac OS X users can utilize Apple's AAC encoder with the command-line afconvert tool.įAAD2 is Freeware Advanced Audio (AAC) Decoder including SBR decoding.The (nonfree) libaacplus which implements the High-Efficiency Advanced Audio Coding.This encoder was replaced in Android by the FDK AAC encoder mentioned above, and is considered a poor-quality option. libvo_aacenc, the Android VisualOn AAC encoder.The AAC encoder used in FFmpeg's version of libavcodec was significantly improved for version 3.0 of FFmpeg and is no longer considered experimental. It was written by Konstantin Shishkov, and released under version 2.1 of the LGPL. The libavcodec native AAC encoder (separate versions maintained by FFmpeg and Libav) was experimental but considered "better than vo-aacenc" in at least some tests.Nero no longer develops this encoder, but the package is still available, and it remains a high-quality option for AAC encoding. The Nero AG-developed " Nero AAC Codec", which has a proprietary license, and is not available for the entire range of hardware architectures that these operating systems are able to run.The library is built around fixed-point math and supports only 16-bit PCM input. The FDK AAC source code is licensed under a custom-copyleft license, and has been ported to other platforms as libfdk-aac. The Fraunhofer-developed " FDK AAC" encoder library included as part of Android.Alternatives for AAC encoding in Unix-like operating systems įAAC is one of six alternatives that Linux/ Unix users have for creating AAC files. The object type "Low Complexity" is the default and also happens to be used in videos meant to be playable for portable players (like Apple's iPod) and used by video-hosting sites (like YouTube).įAAC has been evaluated as a somewhat "lower quality" option than other aac encoders. The SBR and PS object types are not supported, so the HE-AAC and HE-AACv2 profiles are also not supported. The MPEG-2 AAC profiles supported by FAAC are LC and Main. The MPEG-4 object types of the AAC format supported by FAAC are the "Low Complexity" (LC), "Main", and "Long Term Prediction" (LTP). It also supports multi-channel streams, like 5.1. Some of the features that FAAC has are: cross-platform support, "reasonably" fast encoding, support for more than one "object type" of the AAC format, multi-channel encoding, and support for Digital Radio Mondiale streams. AAC files are commonly used in computer programs and portable music players, being Apple Inc.'s recommended format for the company's iPod music player. It contains a library ( libfaac) that can be used by other programs. The FAAC encoder is an audio compression computer program that creates AAC (MPEG-2 AAC/MPEG-4 AAC ) sound files from other formats (usually, CD-DA audio files). FAAC encoder įAAC stands for Freeware Advanced Audio Coder. FAAC contains some code which is published as Free Software, but as a whole it is only distributed under a proprietary license.įAAC was originally written by Menno Bakker. ![]() įAAC and FAAD2, being distributed in C source code form, can be compiled on various platforms and are distributed free of charge. The encoder and decoder is compatible with standard-compliant audio applications using one or more of these object types and facilities. It supports several MPEG-4 Audio object types (LC, Main, LTP for encoding and SBR, PS, ER, LD for decoding), file formats (ADTS AAC, raw AAC, MP4), multichannel and gapless encoding/decoding and MP4 metadata tags. It supports MPEG-2 AAC as well as MPEG-4 AAC. netįAAC or Freeware Advanced Audio Coder is a software project which includes the AAC encoder FAAC and decoder FAAD2.
