STM32-MP3NL/COD
Audio Engine MP3 Codec and Utilities-
Preview
STMicroelectronics STM32 Audio Engine is a set of software libraries allowing customers to build audio applications with high-quality and professional results.
The popular MP3 format is part of the formats a professional application should support to ensure the best musical experience.
Therefore, the MP3 codec library is a must. It removes the need for an external MP3 codec component. Moreover, unlike many open-source solutions, it was written specifically for STM32, and is therefore highly optimized, leaving room for other application tasks to run concurrently with the audio encoding/decoding.
In addition, it comes with a set of impressive add-ons such as a channel mixer, a standalone 5-band parametric equalizer and loudness control to provide a complete plug-and-play solution for STM32 customers.
The MP3 codec library is not available for all STM32 family members.
