STMicroelectronics with DSP concepts to present ST-AudioWeaver

ST has worked with DSP Concepts to present a free version of the tool – ST-AudioWeaver – for developers using its 32-bit ARM Cortex-M-based STM32 microcontrollers. AudioWeaver enables product designers to build complex digital audio applications without coding. Developers simply choose the required audio modules from a library, connect them graphically, and adjust them by live-tuning on the target hardware. Examples are included, which accelerate learning and help jump-start new projects.

“DSP Concepts has created a high-end audio-development experience for the embedded domain. ST-AudioWeaver now gives our customers preferential access to help them make the most of the audio capabilities of STM32 MCUs, which complement the outstanding features and power efficiency for IoT applications,” said Daniel Colonna, Marketing Director, Microcontroller Division, STMicroelectronics.

Dr Paul Beckmann, Founder & CEO, DSP Concepts, Inc., said, “With ST-AudioWeaver, product designers will find it much easier to incorporate advanced audio features in IoT and wearable devices. Audio engineers will love it because it is much like plugging physical components together however you want, then adjusting the knobs and sliders to get everything tuned perfectly, except it is all happening onscreen.”

ST-AudioWeaver contains a library of 160 royalty-free digital audio-processing modules, including versatile and powerful filtering, array-processing and noise-cancelling modules that can make voice-recognition systems far more effective. The AudioWeaver Designer PC GUI is also included free of charge, which lets developers configure the modules and do fine-tuning in the GUI or on prototype hardware. This creates a customized audio-processing engine that runs directly on the production embedded system with no further tailoring required. Users are also free to take advantage of DSP Concepts’ commercial offers to scale and upgrade ST-AudioWeaver, for example by adding further audio modules or MATLAB API support.

The DSP core extensions of the STM32F4, STM32L4 and STM32F7, which are the series currently supported in ST-AudioWeaver, enable a single-chip solution capable of high-performance audio processing, which would otherwise require a separate DSP co-processor.
