Product overview

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, audio conditioning and effects, and any other audio processing use case.

X-CUBE-AUDIO-KIT includes one generic designer firmware for each of the STM32H573I-DK and STM32H735G-DK Discovery kits. Each firmware features a set of algorithms, the AudioChain framework, and the LiveTune interface.
