Audio Engine WMA Decoder and Utilities
  • active 活性

STMicroelectronics STM32 Audio Engine is a set of software libraries allowing customers to build audio applications with high-quality and professional results.

The popular WMA format is part of the formats a professional application should support to ensure the best musical experience.

Therefore, the WMA decoder library is a must. It removes the need for an external WMA decoding 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 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 WMA decoder library is available for all STM32 family members.
