STM32-MP3NL/COD library

Posted by avlijas.sladjan on 2017-11-06 21:28

Hi,

can anyone help me to find source code or lib for mp3 encoder “STM32-MP3NL/COD”. On STM site I only find datasheet:

I think the answer is in the datasheet:

‘’1.1 MP3 background
The popular MP3, short for MPEG-1/MPEG-2 Layer 3, is a format allowing to store digital
audio using lossy compression algorithms. It was patented by Technicolor.

1.2 Royalties and part numbers
Some royalties are due to the patent owner. For the MP3 codec, STMicroelectronics
proposes to embed the royalties in the chip prices, in order to ease customers life, and to
leverage royalty costs on high volumes.
In order to know the quantities of delivered ships, STMicroelectronics is therefore proposing
specific part numbers. Please refer to the product datasheets for more information, or
contact your local ST sales representative.’’
