The devices we wear, carry, and live with are becoming our most personal AI companions—and that demands they be always aware, always private, and always delivering exceptional audio. The Astra™ SR80 Series delivers always-on Edge AI processing and high-fidelity audio in a single, ultra-efficient platform that’s purpose-built for devices that must sense, respond, and sound exceptional.
The Need for Always-On Edge AI Audio
The shift from the cloud to Edge isn’t just architectural—it’s personal. The relationship between a person and their AI agent depends on privacy, continuity, and context. The value of AI isn’t just in answering questions, but also in remembering the conversation, building on history, and growing more useful over time. That evolving relationship is central to what we’re building at Synaptics; the history, the context, and the continuity are what make AI genuinely useful.
Wearables, PCs, smart home, and office devices all have the potential to deepen this relationship, but only if they can actually hear and understand us. Noisy environments, privacy demands, personalization requirements, and power constraints are real barriers, and they all converge at the audio layer. With the Astra SR80 Series, we’re bringing always-on, high-fidelity audio processing to the Edge, removing barriers between people and the AI experiences they deserve.
The Astra SR80 Audio Advantage
Astra SR80 Series Edge AI MCUs deliver high-performance, voice-driven audio processing at ultra-low power. Each device combines advanced audio AI, an integrated CODEC, and high-speed USB in a single, highly efficient platform. With an ultra-compact footprint, the Astra SR80 is a natural fit for voice-first HM applications in wearables, headsets, and USB microphones. The family is also ideal for soundbars, smart doorbells, connected appliances, intercoms, and security panels.
This family of MCUs integrates a programmable Arm® Cortex®-M33 core that provides flexible, low-power compute for custom workloads. It supports always-on context awareness and on-device algorithmic processing, enabling natural and responsive voice-based human-machine interaction.
In real-world environments, Synaptics’ turnkey algorithms—including AI-enhanced environmental noise cancellation (ENC) and premium hybrid adaptive active noise cancellation (ANC)—deliver measurable speech and sound recognition performance. The Astra SR80 Series also supports collaboration use cases, including compliance with Microsoft® Teams™ version 5 requirements.
An integrated Synaptics neural processor unit (NPU) and Tensilica® HiFi 5™ DSP combine proven turnkey capabilities with flexible customization tools, giving design teams the foundation to build the next generation of AI audio solutions. Comprehensive audio tuning software kits further accelerate time-to-market for design teams.
The Astra SR80 Series is built around three core principles that define its architecture and competitive advantage. We call them the three Ps.
Personalization, Privacy, and Power Optimization
The Astra SR80 Series is purpose-built as the audio front end for voice-first HMI and agentic AI systems. It manages both audio input and output with both digital signal processing (DSP) and AI audio.
For years, noise reduction has been an industry focus, but there's more to elevating audio. By running the DSP and AI processing in parallel, the Astra SR80 reduces background noise and cancels non-stationary interference while isolating a specific user’s voice. This enables a unique voiceprint—ensuring audio data only passes downstream to the AI agent when the authorized user’s voice is confirmed. By combining contextual awareness and voice biometrics, the Astra SR80 ensures a secure, private relationship between user and AI agent, one that responds only to the intended person.
Unlike fixed path architectures, the Astra SR80 Series features programmable audio pipelines that process audio locally and privately, enabling design team’ flexibility to adapt to application-specific requirements. Before any interaction with the main SoC or the cloud, the Astra SR80 re-filters contextual data and validates the voice signal, ensuring only clean, verified audio moves forward in the pipeline.
The Astra SR80 Series is engineered for ultra-low power consumption, delivering always-on AI audio at a fraction of the energy required by other approaches.
Together, these three pillars—personalization, privacy, and power optimization—give designers a powerful foundation for building the next generation of voice-driven, human-centric applications.
The Foundation for Multi-Modal Systems
The Astra SR80 Series is engineered for always-on intelligence, continuous context awareness, and ultra-efficient on-device processing. As the ‘ears’ for multi-modal systems, the SR80 serves as the audio front end for Agentic AI devices, Edge AI applications, and multi-factor biometric authentication. When combined with the AI-native Astra™ SR100 series, you get “eyes” added to the equation. The SR100 series brings premium vision processing to the Edge. Together, both series reflect Synaptics’ commitment to building a comprehensive portfolio of high-quality, low-power sensing and processing solutions, establishing Synaptics as a trusted partner for multimodal AI at the Edge.
