Since AAC is better than MP3 and the size is similar, why is AAC audio format not popular on the Internet?
Have patents limited the growth of AAC?
As an upgraded version of the MP3 format, the enhanced sound quality of AAC does not have substantial performance on most audio playback terminals (such as mobile phone speakers, mobile phone compatible headphones, Ai speakers, Bluetooth speakers, etc. .). Also, AAC involves many patents, but only proprietary rights.
The cost of this aspect is no small expense for music publishers and platforms. Therefore, many publishers and merchants choose not to use the AAC format, limiting AAC from the source. Diffusion and popularization, so the AAC audio format is relatively unknown to our public users.
That is to say, for one thing the performance is not noticeable on much of the playback equipment available. Not on any computer, phone, tablet, etc. the difference in audio quality is noticeable when buying an AAC and an Mp3.
On the other hand, expensive patents have to be paid, even though they may not make a difference in the ears of the customers, and to this we must add that mp3 is known all over the world.
Mp4Gain can convert mp3->aac and vice versa and normalize both audio formats.
