FAAC (Freeware Advanced Audio Coder) is a software project which includes the AAC encoder FAAC and decoder FAAD2. It supports MPEG-2 AAC as well as MPEG-4 AAC. 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. The encoder and decoder is compatible with standard-compliant audio applications using one or more of these object types and facilities.[1] It also supports Digital Radio Mondiale.[2]

FAAC and FAAD2, being distributed in C source code form, can be compiled on various platforms and are distributed free of charge. FAAD2 is free software. FAAC contains some code which is published as Free Software, but as a whole it is only distributed under a proprietary license.

FAAC stands for Freeware Advanced Audio Coder.[4] The FAAC encoder is an audio compression computer program that creates AAC (MPEG-2 AAC/MPEG-4 AAC[5]) sound files from other formats (usually, CD-DA audio files). It contains a library (libfaac) that can be used by other programs.[6] 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.

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. It also supports multi-channel streams, like 5.1.[7] The MPEG-4 object types of the AAC format supported by FAAC are the "Low Complexity" (LC), "Main", and "Long Term Prediction" (LTP).[2] The MPEG-2 AAC profiles supported by FAAC are LC and Main.[8] The SBR and PS object types are not supported, so the HE-AAC and HE-AACv2 profiles are also not supported. 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).

FAAD is Freeware Advanced Audio Decoder. It was first released in 2000 and it did not support SBR and PS audio object types.[22][24][25] The last version of FAAD1 was 2002-01-04. All development later focused in FAAD2.[26] The SBR decoding support (HE-AAC) was added in the version release on 25 July 2003. FAAD2 version 2.0 was released on 6 February 2004.[21][27]

FAAC contains code based on the ISO MPEG-4 reference code, whose license is not compatible with the LGPL license.[2] Only the FAAC changes to this ISO MPEG-4 reference code are licensed under the LGPL license.[2] The ISO MPEG-4 reference software was published as ISO/IEC 14496-5 (MPEG-4 Part 5: Reference software) and it is freely available for download from ISO website.[28][29] ISO/IEC gives users of the MPEG-2 NBC/MPEG-4 Audio standards free license to this software module or modifications thereof for use in hardware or software products claiming conformance to the MPEG-2 NBC/MPEG-4 Audio standards. Those intending to use this software module in hardware or software products are advised that this use may infringe existing patents.[3][30][31]

FAAD2 is licensed under the GPL v2 (and later GPL versions). Code from FAAD2 is copyright of Nero AG (the "appropriate copyright message" mentioned in section 2c of the GPLv2).[32] The source code contains a note that the use of this software may require the payment of patent royalties. Commercial non-GPL licensing of this software is also possible.[33]

Founded in Italy nearly 60 years ago by Giuseppe Manini, the creator of the first automatic gate handling system, FAAC Technologies has evolved into a global leader in access and parking solutions. The Parking Business Unit, established in 1993, expanded with the acquisitions of ZEAG and Datapark in 2011 and 2012, respectively, and was renamed HUB Parking Technology. Since then, the unit has grown significantly, driven by global expansion, product investments, and strategic acquisitions such as CTR Parking Systems, Signature Control Systems, Parclick, TIBA Parking Systems, and Pink Park. The creation of UK-based FAAC Mobility Services in 2023 further exemplifies this growth.

Today, FAAC Parking Solutions supports customers in more than 40 countries and serves thousands of parking asset locations. Our company is dedicated to strengthening current customer relationships while pursuing additional growth.

Over recent years, diffusion models have facilitated significant advancements in video generation. Yet, the creation of face-related videos still confronts issues such as low facial fidelity, lack of frame consistency, limited editability and uncontrollable human poses. To address these challenges, we introduce a facial animation generation method that enhances both face identity fidelity and editing capabilities while ensuring frame consistency. This approach incorporates the concept of an anchor frame to counteract the degradation of generative ability in original text-to-image models when incorporating a motion module. We propose two strategies towards this objective: training-free and training-based anchor frame methods. Our method's efficacy has been validated on multiple representative DreamBooth and LoRA models, delivering substantial improvements over the original outcomes in terms of facial fidelity, text-to-image editability, and video motion. Moreover, we introduce conditional control using a 3D parametric face model to capture accurate facial movements and expressions. This solution augments the creative possibilities for facial animation generation through the integration of multiple control signals. For additional samples, please visit -faac.github.io/.
