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. ST presents this special offer for free to the STM32 customers and adds the support of a number of ST audio modules such as virtualization and bass enhancement. Premium upgrade of ST-AudioWeaver with additional or custom audio modules and MATLAB® API support, is possible using DSP Concepts commercial offers. The user can also license a software solution such as DSP Concepts "Voice UI".
