In this chapter at the beginning of this article, we will explain the characteristics and differences between the MP3 file format and the AAC file format. Many people generally recognize that both MP3 and AAC are file compression formats dedicated to music and audio, but not many people clearly understand the difference between MP3 and AAC.
A solid understanding of the differences between MP3 and AAC will help you choose the correct file format, so it is important to remember each file format first.
MP3
MP3 is the oldest music file storage format for smartphones and computers. MP3 is a format that compresses music files and is characterized by a large number of compatible devices. MP3 is a music compression format, but there is a video compression format called MP4.
The names of both formats are similar, but watch out for mistakes as they are completely different formats. MP4 is also a well-known video compression storage format, so it’s a good idea to keep that in mind.
AAC
AAC is also known as alias “M4A”, “M4P”, which was established as the music compression format for the upcoming MP3, the standard compression format for Apple products such as the iPhone and iPad. When you purchase paid music content from iTunes, all purchased music files are saved as “AAC” files in iTunes.
Files saved in AAC format apply to copyrighted music content.

I will present the common points between MP3 and AAC. Both are compression methods for digital music content, but I will introduce the compression format and the advantages of compression.
The MP3 / AAC compression format is “lossy compression format”
The MP3 / AAC music content compression format is called “lossy compression format” and they both have the same compression format. Digital music data is usually a 1 minute music / audio file with a large size (capacity) of 10 MB, but since it is compressed with the MP3 / AAC “lossy compression format”, the download speed is fast and the storage capacity is increased. It does not squeeze.
Data file compression (capacity) of music content makes sound quality worse than live audio, but falls within the range of sound quality that can be heard by the human ear, so there is no problems such as interruptions in sound.
