Advanced audio development tool for STM32

ST-AudioWeaver is an ST subsidized release of the leading Audio Weaver™ audio development system developed and commercialized by DSP Concepts.

ST-AudioWeaver is an advanced tool for easy and optimized audio development and tuning on STM32 microcontrollers.

The PC based tool utilizes a graphical interface that enables creating and tuning of advanced audio processing chains by simply dragging and dropping 160+ modules.

No DSP coding skills are required. When using the runtime core libraries, the output is optimized embedded code, ready for production, which significantly reduces development time and costs.
