STM32 projects offered free access to no-coding audio design tool
Small electronic products such as wearables and IoT devices can now provide high-end audio features, including advanced aural user interfaces, thanks to this easy-to-use graphical design tool for STM32 microcontrollers, the company says. Audio Weaver 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 and CEO of DSP Concepts, Inc, added, “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’s much like plugging physical components together however you want, then adjusting the knobs and sliders to get everything tuned perfectly-except it’s all happening onscreen.”
ST-AudioWeaver contains a library of 160 royalty-free digital audio-processing modules, including filtering, array-processing and noise-cancelling modules. The Audio Weaver 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-Audio Weaver, for example by adding further audio modules or MATLAB API support.
STM32 microcontrollers include peripherals such as I²S and S/PDIF digital audio interfaces, and a DFSDM input that streamlines acquisition of MEMS-microphone signals for voice-command applications. 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.
