AAC is one of the most widely used audio formats today. It is not only characterized by its popularity, but also by the quality it offers compared to other formats.
What is the AAC format?
AAC is short for Advanced Audio Coding and is a popular digital audio format. It was born with the intention of being the substitute for the MP3 format since it offers higher quality with a lower bit rate.
It is within the ISO/IEC standard and belongs to the group of MPEG-2 and MPEG-4. It is not compatible with MPEG1. It usually has better functions than MP3, even though MP3 is more widely used.

CCA use
The AAC format is mostly recognized for being used on Apple device platforms, such as Ipod and Iphone. The program they use for playback is iTunes.

It is also often used by applications such as Winamp, Ahead and Nero. Like the Nintendo DS it makes use of the format.
The reason why it is usually used in these media is because of its ability to shield the content. AAC allows you to include copyright protection on files.

AAC is presented as one of the audio formats that directly competes with MP3. That is why it is important to highlight the benefits offered by this form, which has been on the market for some time, but is less well known.
Sound quality
This format not only offers superior sound quality to MP3, but also offers multi-channel support. This means that multiple audio channels can be integrated into a single file. It is for this reason that it is used in film audio.
Copyright Shield
An AAC file cannot be freely shared if it is encrypted with copyright. It is the reason why it is the format preferred by Apple, since it avoids the massive reproduction of a song without paying for it.
lighter files
Thanks to its excellent audio compression, the file size is usually smaller than the MP3 format. A song in AAC format can take up half the memory space and with better sound quality.
Add more files to your music player without affecting storage capacity. This feature makes it a popular format for podcasts and broadcasts.
