STM32-WMA/DEC STM32 audio engine – WMA decoder library
●Description
■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.
