New I/O support
16 and 32 bit support from input to output peripherals
Description
The X-CUBE-AUDIO-KIT Expansion Package provides an integrated platform for designing, implementing, and fine-tuning audio processing data flows on supported series of STM32 microcontrollers.
With LiveTune, a graphical user interface accessible through an HTML5 navigator, users can design and fine-tune data flows in real time on STM32 devices.
The Expansion Package includes a library of algorithms from STMicroelectronics and external sources.
Additionally, the users can integrate their own custom algorithms into the environment, allowing their execution and fine-tuning within the data flows.
This Expansion Package aims at use cases such as:
- Voice denoising for speech recognition or voice communication
- Audio output enhancement
- Audio conditioning
- Sound generation
- Audio effects
- Any other audio processing use case
X-CUBE-AUDIO-KIT includes one generic designer firmware for each of the STM32H573I-DK, STM32H735G-DK, and STM32N6570-DK Discovery kits. Each firmware features a set of algorithms, the AudioChain framework, and the LiveTune interface.
