STM32-MP3NL/COD

Audio Engine MP3 Codec and Utilities




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.

Key Features

  • MPEG-1, 2 or 2.5 formats
  • Layers 1, 2 and 3
  • Constant bit rate and variable bit rate
  • Mono or stereo input streams
  • PCM (Pulse Code Modulation) output
  • Solution optimized for STM32
  • MP3 decoder with built-in equalizer
  • MP3 encoder
  • Audio utilities:
    • Channel mixer utility (for volume and mute control)
    • Standalone 5-band parametric equalizer utility
  • Loudness control utility
  • Object codes, accessed by the user application through an extensive API in C
  • Full documentation included, demo software available
  • Demo project available for IAR EWARM, Keil MDK-ARM and Raisonance RIDE
