File extension: .m4a, .aac, .mp4
Specifications for the most common AAC LC mode:
The format is part of the MPEG Audio standard ISO / IEC 13818-7... It was created by the German Institute Fraunhofer IIS and is further development MP3 format.
The format itself is proprietary and requires the purchase of a license for commercial use.
History
The development of the format began in 1994 with the joint efforts of Fraunhofer IIS, AT&T, Dolby and Sony. Only three years later, the format became part of the MPEG standard as MPEG-2 AAC. With the subsequent development of the MPEG-4 audio standard, AAC has been improved and refined.
In general terms, the chronology of the development of the format is as follows:
- 1997 - standardization MPEG-2 AAC-LC.
- 1999 - standardization MPEG-4 AAC-LC... Added PNS (Perceptual Noise Substitution) technology.
- 2003 - standardization MPEG-4 HE-AAC... Added SBR (Spectral Band Replication) technology.
- 2004 - standardization MPEG-4 HE-AAC v2... Added PS (Parametric Stereo) technology.
HE-AAC is a low bitrate oriented format. The combination of AAC LC and SBR used in it gives good quality at bitrates from 32 to 48 kbit / s. Naturally, HE-AAC supports multichannel and allows for a rich selection of sample rates. HE-AAC also known as aacPlus.
When combined with parametric stereo HE-AAC v2 provides good audio quality at bitrates of about 16 kbit / s for stereo. HE-AAC v2 also known as aacPlus v2.
Profiles
- LTP / Long Term Prediction, MPEG-4 only
Some profiles are of low complexity, so they are preferable for portable devices, but they also give a slightly weaker quality. Nevertheless, the most common profile at the present time is, since other more demanding profiles (Main, LTP) do not provide as much quality as they are more demanding on computational resources.
Headings
There are 4 types of headers in AAC:
- LATM (Low-overhead MPEG-4 Audio Transport Multiplex)
- LOAS (Low overhead audio stream)
ADIF
This header format is intended for simple local storage, unlike ADTS and LATM / LOAS, which are intended for mobile AAC transmission.
ADTS
qaac
There is an open source implementation of a wrapper for AAC from Core Audio and ALAC called qaac from developer nu774, it only works on Windows. At the time of the article update, this is the most current AAC codec.
Nero Digital Audio
Starting with the fifth version, the Nero package comes with an AAC codec. Now he is part of Nero Digital - a project to create a new standard in the world of digital video and audio. Nero AAC can create two types of AAC: LC and HE. Low Complexity (LC) is a common AAC standard, while High Efficiency (HE) uses SBR technology (similar to mp3PRO), and if the player understands this technology, additional frequency information can be decoded, otherwise half of the audio quality is lost during playback. At the moment, the codec is significantly outdated and its quality is inferior to the implementation from Apple. This codec is very convenient to use together with the dBpowerAMP Music Converter program and the corresponding codec for it (dBpowerAMP Nero MP4 Codec).
Advantages of Nero MPEG-4 AAC (LC profile):
- In all cases, the quality is noticeably higher than that of the LAME MP3 with smaller file sizes.
- Low resource consumption compared to the latest versions of LAME MP3 (VBR / ABR).
Psytel AACenc and Fastenc
PsyTEL® FAST MPEG-2 AAC LC Encoder v2.0 (build Mar 4 2002) / Copyright © 1999-2001 PsyTEL Research / Copyright © 1999-2001 Ivan Dimkovich
Yugoslavian company Psytel Research has been working on improving the MPEG-2/4 AAC standard. It was founded around 1998 by programmer Ivan Dimkovich.
While the first version (1.0) was roughly a compilation of ISO source codes, quality started to increase rapidly and, after a while, it was the only truly optimized ISO AAC encoder available to the public (versions from FhG and Dolby were only available to developers interested in in improving their technology). Liquifier was also available, but the data streams created by it were encrypted.
By mid-2002, Psytel Research and all of its assets were bought by Ahead Software GmbH, and AACEnc became Nero AAC Encoder.
FAAC (Freeware Advanced Audio Сoder)
In late 1999, Menno Bakker opened the source code for his developments and founded the FAAC (Freeware Advanced Audio Coder) project. The FAAD2 decoder is considered one of the best and fastest AAC decoders today. The FAAD2 (Freeware Advanced Audio Decoder) project has Copyright © 2003-2004 M. Bakker, Nero Software AG. For licensing, contact Nero Software AG.
HomeBoy AAC
HomeBoy was the name of the group of programmers who created the first publicly available ISO AAC encoder for Windows back in 1998. They reportedly also created the first third-party plugin for Winamp (their AAC input plugin), thus making it available to the general public first ISO AAC decoder. The encoder is just a compilation of the original ISO related source codes, so the quality was poor. But what is interesting is that the data streams created by him are still decoded in modern decoders.
Versions
Dicas / zPlane Compaact!
AAC Codec Compaact! was developed by German DSP engineer, Alexander Lerch. The release took place in 2003. The codec was well received after its release. It also contained some interesting features. There were three quality levels (from fast to high-quality encoding), Main profiles were also supported, it was possible to enable or disable technologies such as TNS or PNS, support for multi-channel encoding, some preprocessing operations and a very interesting pre-listening feature that allowed you to hear in real how long the songs will sound after compression. For unknown reasons, the project was stopped in 2005.
Versions
MBsoft AAC
The project began around 1998 when German programmer Menno Bakker began work on the AAC source code. Encoder mbaacenc was more or less an ISO source code build with a good front-end. A plug-in for Winamp was also available.
In late 1999, Menno opened the source code for his developments and founded the FAAC (Freeware Advanced Audio Coder) project. The project is still alive, and its decoder, FAAD2, is considered one of the best and fastest AAC decoders today.
I would like to introduce you to the same audio format as AAC.
What are the advantages of this AAC format over others, for example over mp3?
Up to 48 audio channels;
Greater coding efficiency with both constant and variable bitrates;
Sampling rates from 8 Hz to 96 kHz (MP3: 8 Hz - 48 kHz);
More flexible Joint stereo mode.
> To put it simply, AAC is not only the best format compared to others, but it also has advantages.
Do you still store your music in MP3 and LOSSLESS?
Our answer to this is only AAC! Judge for yourself: the largest social networks use this format in videos, which can significantly save space on their hard drives. The format is supported by most modern phones that are capable of playing mp3, wma. For example, Nokia Corporation records standard ringtones in their phones in the AAC format. Are you not convinced of its superiority yet? Then let's move on to the numbers ...
When compressed from MP3 to 3GPP AAC +, the music file loses its weight by at least THREE times!
That is, we take a file with a sound bitrate of 320 kbps, and at the output we get a bitrate of 48 kbps, We count 320/48 = 6.666. That is, potentially the MP3 file can be reduced to SIX TIMES!
Now imagine that your 40GB MP3 audio library is cut by three times 40/3 = 13! TOTAL THIRTEEN GB! At the same time, the sound quality DOES NOT HAVE ANYTHING... If you are in doubt, I will say this: I store all my music in AAC format, so three years ago I had a 40GB hard drive. Yes, yes, don't be surprised) So I started looking for methods to shrink my audio library. I didn't want to delete the music, I just transferred everything to AAC. Of course, on my AMD 1500+ it happened in stages and not as fast as I would like, but I did it!
Would you like more information?
Today, hard drive manufacturers are interested in buying their product. In this regard (believe it or not) you are forced to download more and more, store the greatest amount of information on your disks, in the most bulky file size. For example, Modern BluRay video formats. I do not argue that if you have a giant screen, then you just have to use this format, but if you use ordinary monitors, up to 22 ", then tell me why you should watch movies in a format, the picture of which is larger than your monitor?
What about LOSSLESS?
Guys, finally understand that this format was created for special use in those places where it is really necessary. For normal listening through a player on a computer HE'S NOT NEEDED! Lossless is be s a useful waste of disk space. By ear, a person cannot perceive the difference between quality AAC and Lossless. Therefore, I recommend this format to you. Of course, you will immediately react with distrust, but ... I would advise you to try this. And you will understand yourself that you cannot find a better one!
What are the disadvantages of AAC?
I understood the merits of this format, but how do I recode my music?
I would advise you to use MediaCoder... It is a great encoder for your media files. Supports a huge number of formats, is free s paid.
How exactly to encode?
2. Install in a couple of clicks, click Next> ...
3. Open the folder with your music, throw it into MediaCoder and choose the format.

The AAC Audio file format
AAC files were developed to replace MP3 files. Lossy compression allows you to get better sound quality at the same bitrates. AAC files are standardized by ISO / IEC as building blocks of the MPEG-2 and MPEG-4 file families (they were originally members of the MPEG-2 Part 7 file group). AAC files contain more sample rates (compared to MP3) and up to 48 channels. Significantly improved coding efficiency and more filterbanks included. Improved transient signal encoding accuracy. Like MP3 files, AAC files cut the sound of frequencies that the person cannot hear. This allows the file size to be reduced. Compared to MP3, AAC files are significantly smaller.
Technical details of AAC files
MPEG-2 part 7 files are represented by three file types: low complexity AAC-LC, basic type (AAC Main), and variable sample rate (AAC-SSR) files. AAC files allow for temporal noise shaping, non-uniform sampling, and bitstream reformatting (for 16 stereo, 16 mono, 16 low frequency channels, and 16 annotation channels in a single bitstream). In 1999, the MPEG-2 part 7 format was included in the MPEG-4 Part 3 format. This allowed the introduction of audio object types, as well as the technology of permanent noise replacement. The AAC format is currently described in the ISO / IEC 14496-3 standard. Audio masking is used in lossy compression to remove unnecessary information while maintaining quality.
