IA8201 Evaluation Kit

The IA8201-RDI-01 is an evaluation kit based on the Knowles AISonic^TM audio edge processor IA8201. The Knowles IA8201 is a high-performance, ultra-low-power audiocentric OpenDSP supporting up to 4 mics, multiple high-speed interfaces, and GPIOs in two package options.

To achieve low power and compact design, the evaluation kit is designed to be implemented with a readily available Raspberry Pi board.

Use Case Examples for IA8201

• Low power voice wake: Listens for specific OEM keywords to wake the host processor. Large memory enables processing of multiple stages on-chip for accurate results.
• Proximity detection: When combined with an ultrasonic capable speaker and microphone, detects the distance between the system and an object; can replace an IR-Prox sensor in bezel-less phones.
• Hub: Determines location of voice source while tuning out a noisy environment and lowering music to detect voice commands. Simultaneously takes metadata input and overrides beamformer to focus on camera-tracked objects.
• Security System: Activate with a voice command. Detect glass breakage/smoke alarm, log direction of noise source, trigger alarm, and send alerts through Wi-Fi connection.
• Wireless earbuds: Delivers low-power premium wake-on-voice performance, talk detection to eliminate false triggers, enhanced voice quality through advanced beam forming, noise reduction algorithms, and support for local commands, including answer/ignore calls.
