Discover how to streamline and simplify development of embedded audio applications for richer user interfaces in smart devices.

Small electronic products like wearables and IoT devices can now provide high-end audio features, including advanced aural user interfaces, thanks to an easy-to-use graphical design tool for STM32™ microcontrollers.

ST has partnered with DSP Concepts, the creator of the Audio Weaver design suite, to present a free version of the tool, ST-AudioWeaver, providing TalkToTM audio front-end for voice UI features. Audio Weaver enables developers to create complex audio features by dragging and dropping DSP modules and configuring them in a design sheet. You don’t have to know the details of programming a DSP in assembly or “C” code to create compelling audio features.

STM32F4, and STM32F7, and STM32H7 series MCUs offer signal processing capabilities close to what standard DSPs can achieve; and this comes with lower run and stop power consumption and richer connectivity allowing developers to combine audio processing, rich connectivity, and real-time control in a single-chip solution.

The ST-AudioWeaver tool includes over 160 modules that will work for the STM32 ARM® Cortex® M4 and M7 families of devices. This is a tool that provides a modular approach to enabling a customer to quickly create audio features that can go from prototype to production immediately, saving considerable design time and cost.

In this 1-hour session, DSP Concepts’ Kevin Kluka and ST’s Greg Davis present an overview of ST-AudioWeaver including its capabilities, basic design principles and techniques, use cases, plus testing and debugging essentials. Attendees will experience a demonstration with and without an audio front end to better understand the design process for a more successful product outcome.
